FROM THE PUBLISHER

SUSAN GIBSON JSJ Productions, Inc.

Predictions Here is the current AI prediction on the economy: “The US economy is predicted to experience slower growth in 2025, driven by factors like tariffs and policy uncertainty, while inflation is expected to remain near 3.0%.

Globally, growth is projected to be around 3% in 2025 and 2026, with slower growth in the US and China impacting emerging markets. Increased restrictions on trade and investment, as well as subsidies and industrial policies, are expected to shape operations, especially in economies with significant trade with the US and/ or China.”

Some key predictions of interest to our industry are: • Inflation is predicted to remain near 3.0% in 2025. There is potential the Fed will cut interest rates in September.

• Increased restrictions on trade and investment, as well as subsidies and industrial policies, are expected to reshape operations.

• Job growth is expected to decelerate from 160,000 per month in 2024 to around 90,000 in 2025.

• The federal funds rate is expected to remain in a 4.25%4.50% range, with economists predicting a potential cut starting in September.

• Manufacturing activity is expected to continue to slow, with some reports suggesting a potential recession in the sector.

• The technology industry is

expected to continue to grow, with investments in artificial intelligence, cloud computing, and cybersecurity likely to remain strong.

• Energy demand is expected to remain strong, with a focus on renewable energy sources and energy efficiency.

Factors influencing these predictions are tariffs, which are expected to have a significant impact on the US economy, slowing growth potentially leading to higher Celal Beysel, Flotels, marks his tracks in India! prices, and policy uncertainty expected to impact economic growth.

Beaulieu Fibres Drive ‘The Cleaner Car’ with Lower Impact Plastics for Automotive Parts

WIELSBEKE, BELGIUM – With plastics making up 12-15% of a car’s total weight, reducing their carbon footprint is essential for the future of sustainable mobility. As a leading supplier of advanced polymer fibres, Beaulieu Fibres is addressing this challenge, taking the next step in support of the automotive industry’s transition to low-carbon materials.

To help Tier 1 and Tier 2 players, as well as automotive brands make informed material choices, Beaulieu Fibres now provides detailed CO₂ footprint calculations for polypropylene (PP) fibres used in automotive parts such as underbody shields, door panels, and parcel shelves. These cradle-to-gate lifecycle calculations follow the industry standards.

“When PP fibres are made from circular materials—whether bio-circular or recycled—they significantly reduce CO₂ emissions while maintaining the high-performance standards required in automotive applications,” says Gillis Beun, Business Development Manager at Beaulieu Fibres.

Collaborating for Cleaner Cars

Beaulieu Fibres has been a trusted partner to the automotive industry for decades, supplying highquality raw materials for compression-moulded nonwoven parts. The company actively collaborates across the entire value chain—from Tier 3 suppliers to OEMs—to scale sustainable solutions that drive real impact.

“As raw material providers we have a dedicated Scope 3 program in place to drive sustainability efforts throughout the automotive supply chain,” adds Gillis Beun. “We invite all stakeholders to join us in developing cleaner, lower-carbon mobility solutions.”

Elkhart Plastics, A Myers Industries Company, Introduces Vertical Water Tanks to Help Protect People, Property, and Resources AKRON, OH USA – Elkhart Plastics, a Myers Industries Company and recognized leader in rotational molding, introduced its new Vertical Water Storage Tanks—broadening its product portfolio and marking its entry into a new market.

Elkhart Plastics, a Myers Industries Company and recognized leader in rotational molding, introduced its new Vertical Water Storage Tanks—broadening its product portfolio and marking its entry into a new market.

Designed to protect people, livestock, crops, and property, these vertical storage tanks support a wide range of commercial and residential water needs.

From crop irrigation and livestock care to manufacturing processes and fire suppression, they provide reliable access to water—critical in regions facing water scarcity. The tanks also protect resources by enabling bulk water storage, well water collection, and rainwater harvesting.

Elkhart’s Vertical Water Storage Tanks have been engineered for durability and cost-efficiency, making them the ideal choice in many operations. Constructed from UV-resistant, FDA-approved highdensity polyethylene, the tanks come with a 10-year limited warranty and currently are available in four sizes—1,000-, 1,500-, 2,500-, and 3,000-gallon capacities—with more sizes planned.

The tanks also feature key design elements that enhance performance: • Multiple connection points—risers and tie-downs with flat surfaces offer greater flexibility for additional fittings • Dual manway lids—provide more flexibility for secure top-down access • Integrated air bleeds—help maximize fill efficiency and minimize fill time • Tough tank top—large radii and increased wall thickness safeguard against sun exposure “The launch of our Vertical Water Storage Tank underscores our commitment to innovation, quality, and sustainability,” said Cullen Jones, V.P. of Sales 16 ROTOWORLD® ISSUE 1 • 2025

for Rotational Molding at Myers Industries. “As water becomes an increasingly precious resource, effective storage and conservation are vital to maintaining ecosystems, supporting human populations, and ensuring a sustainable future. These tanks demonstrate our dedication to delivering economically viable and environmentally responsible solutions to customers.”

The Vertical Water Storage Tanks are available for purchase directly from Elkhart or through the company’s dealer network.

K 2025 Features Start-Up Zone and Start-Up Pitch Towards Zero Innovative minds present pioneering ideas for the plastics and rubber industry.

Following its successful launch at the last K, the Start-up Zone will once again be an integral part of the trade fair in 2025 — this time in the immediate vicinity of the Science Campus. New will be the Startup Pitch as part of the Special Plastics Shape the Future.

Start-up Zone

With the Start-up Zone, K in Düsseldorf (Germany), the world’s leading trade fair for the plastics and rubber industry, will once again offer young companies a dedicated stage from October 8 - 15, 2025. Start-up companies in particular play a decisive role for the plastics and rubber industry, as they bring innovations and fresh ideas to an industry that is increasingly confronted with challenges such as sustainability, efficiency, and digitalization.

Especially start-ups are characterized by a great pioneering spirit, a willingness to take risks, and a high degree of flexibility.

The Start-up Zone will be located in Hall 7.0 at K 2025 and thus for the first time in the direct vicinity of the Science Campus. In the Science Campus, universities (of applied science), and institutes will present the latest results of their plastics research.

The two K Specials complement each other perfectly.

The close proximity of the Start-up Zone and Science Campus will make Hall 7.0 a unique science and innovation hub.

Young companies still have the opportunity to register for the Start-up Zone and take advantage of the opportunity to present their developments at the industry’s most relevant trade fair and to make valuable international business contacts. A special participation package has been put together to minimize the hurdles and organizational efforts associated with participating in such a large trade fair. Participation criteria includes: The company is less than 10 years old.

• It has fewer than 100 employees • Annual sales do not exceed € 10 million The registration form can be downloaded at www.k-online.com/Start-up Zone The contact person for the Start-up Zone is

Startup-Pitch Towards Zero

In line with the Start-up Zone, the official Special Plastics Shape the Future, organized by Plastics Europe, will also offer newcomers in the industry a dedicated forum at K for the first time — the Startup-Pitch Towards Zero. Here, start-ups whose innovations and technologies, solutions, or new business models contribute to a circular economy with plastics, to the decarbonization of the plastics industry or to the reduction of so-called Scope-3 emissions, will have the opportunity to present their pioneering technology projects and network with partners worldwide.

The Startup-Pitch Towards Zero will take place on October 13 during K, as part of the Special Plastics Shape the Future in Hall 6 of the Düsseldorf fairgrounds.

Why is venting large moulds different to venting small moulds?

R O R Y J O N E S , L A P L A S T E C N I C A LT D

Mould venting is perhaps one of the least understood aspects of the rotational moulding process, and yet it contributes greatly to the quality of the product. A literature survey suggests that very little research work or theoretical analysis of venting has been carried out over the years.

However, in 2001, research carried out by the University of Auckland[1] set about to mathematically model venting in Rotational Moulding. This was a continuation of the work started in 1996 by Dr Paul Nugent[2].

The research at Auckland[1] resulted in equation 1. This equation is a combination of the Ideal Gas Law, Bernoulli’s principle and Darcy Weisbach approximation of fluid flow in a pipe. However, it is unknown if this groundbreaking work has had any impact on how the rotational moulding industry vents molds, as no reference for anyone using Equation 1 for sizing an actual vent has been found.

One possible reason for this model not being used by the industry is because vent diameters predicted by this equation are generally smaller than are commonly observed in practice. In other words, the industry tends to use larger vents than predicted by this equation.

Σkƒρa V ΔT ms ms 8 V ΔT )( 1 ) ( 16μL + D4 = πχP ( 1 ρ π ρs T Δt T Δt s i 1 1

))

Equation 1

Where: D = Vent Diameter X = Allowable % over pressure Vi = Initial Volume of the mould T1 = Initial temperature of the air in the mould Pi = Initial pressure of the air in the mould µ = Kinematic viscosity of air ρ = Density of air f = Friction factor for a pipe Σkf = Sum of Fanning friction factors L = Length of vent π= pi (3.14) If larger vent diameters than predicted are common, then why does the rotational moulding industry still have venting problems? Venting problems continue for one of two possible reasons: 1. Venting configurations either change during the moulding cycle or over several cycles, and become less effective during processing 2. The assumptions made while creating this equation are not correct

Figure 1: Examples of a build-up of material in vent pipes

www.rotoworldmag.com 25

How are Vents Modified?

The most common way vents are modified is by filling the vents up with some sort of packing material to stop the powder from falling out. Equation 1 can make an allowance for this using the Σkf term, which is a sum of Fanning friction factors. Friction factors account for extra friction associated with the beginning or end of a pipe, and surface roughness in a pipe or packing material. The most significant

Figure 2: Teflon vent with material accumulating inside it

consideration here is the effect of packing material, which is installed in the end of the vent tube. Not only does the packing material friction factor change every time the operator installs packing, but often the friction factor will change throughout the cycle as plastic powder accumulates in the packing material and then starts to melt – see Figure 1.

In summary, every time a vent is packed, it will have a different optimal vent diameter. Also, that optimal vent diameter will change during the moulding cycle as material accumulates and changes state. The other common way we modify vents is by allowing plastic to accumulate inside during the life of the vent. This can modify the surface roughness and reduce the internal diameter of the vent as demonstrated in Figure 2.

Incorrect Assumptions?

One of the assumptions made when developing Equation 1 is that the volume of the mould is fixed.

This is actually never true in rotational moulding as

26 ROTOWORLD® ISSUE 1 • 2025

the mould will expand as it is heated and contract as it is cooled. However, this effect is small and will have a net effect of reducing the amount of air that needs to flow through the vent during both heating and cooling.

The real problem with the fixed volume assumption is when we examine large moulds (often sheet steel). Consider a 25,000L (5500 US gal) tank for example. This mould might be over 3 m (10ft) in height and diameter, and manufactured from 3mm sheet steel. A load of 450kg (1,000 lbs) of material is placed into the mould and then it is rotated in a large oven. This shape and size of mould is challenging to reinforce, so it is highly likely that the mould will flex and deform as it rotates during the heating and cooling cycles as the material continuously moves inside the mould. Also, the frequency and intensity of mould’s flexing will be directly related to the rotation speeds. With larger moulds, the air movement in and out of the vent will be driven by the movement of material inside the mould causing flextion of the mould. This will be a much more significant driver of air through the vent than thermal expansion and contraction from Equation 1. It might be helpful to consider the mould as behaving like a set of bellows, driving air back and forth through the vent. This “bellows effect” becomes our vent design condition.

The question is, how much of an impact will this bellows effect have? With reference to the previously mentioned 25,000 L tank, as the air inside the mould heats up to a typical peak internal air temperature for a large tank of 180°C (360°F) it will expand by approximately 15% or 4,000 L (~1000 US gal) over approximately 30min of the heating cycle. Now if the cascading powder inside this mould causes the mould volume to change by 0.5% (125L or 30 US gal - likely a conservative estimate), then the bellows effect becomes the predominant driver of gas flow through the vent if the cascade is happening more regularly than once a minute.

Additionally, the bellows effect is going to be driving the air both in and out of the vent.

How Small Moulds Differ from Large Moulds

With a smaller fixed mould volume, it can be determined with reasonable certainty what pressure will be experienced in the mould depending on the internal air temperature. As moulds get bigger, they are more likely to act as bellows and they are likely to experience oscillating pressure

throughout the cycle. The principal question is how much the mould is flexing? If a mould is flexing a lot, some operators may want a sealed mould to help support the structure of the mould, while other operators might specify a large vent to ensure pressure fluctuations are minimised. This should be discussed prior to mould construction with the mould builder and the engineering team.

Another difference between small moulds and larger moulds relates to how parts need to be cured/processed. Larger moulds typically produce thicker walled parts with long cycle times requiring significantly lower peak internal air temperature (PIAT) than smaller moulds. For example, large tanks with open, non-pressurised vents, moulded to PIAT of 160°C (320°F) have shown a consistent tendency to pass low-temperature impact tests. To produce good quality smaller parts (with a similar resin) to this level of low PIAT an operator would typically have to utilise some form of active or passive pressurisation technology to help remove bubbles from the wall of the part. La Plastecnica Ltd has developed a range of vents specifically

they are used based on the customer’s own internal evaluation and suitability on a case by case basis.

As always, La Plastencia vents will cause no more damage to a mould than if it were run with a blocked vent. If a solution to stop material falling out of the vents of large moulds is required, La Plastecnica has developed a 40mm (1 1/2”) Intellivent, as shown

“LARGER MOULDS TYPICALLY PRODUCE THICKER WALLED PARTS WITH LONG CYCLE TIMES REQUIRING SIGNIFICANTLY LOWER PEAK INTERNAL AIR TEMPERATURE (PIAT) THAN SMALLER MOULDS.” in Figure 3. This vent is based on La Plastecnica’s one-way venting architecture but is designed to ‘fail’ readily, allowing air to exit the vent more easily.

Conclusions

Figure 3: La Plastecnica 40mm (1 1/2”) Intellivent

designed to help pressurise small moulds; moulds for which the assumption of fixed volume holds true.

As a supplier of vents to the industry, La Plastecnica cannot recommend the use of their engineered venting solutions in large moulds; moulds which act as bellows. La Plastecnica has many customers using vents in large moulds but

This article has explained some of the factors involved in designing vents. Readers are encouraged to remember that the type of vent used will determine the pressure response inside parts. The pressure response will define what the optimum moulding parameters are. How a mould is vented defines how parts need to be processed.

This is a topic that the author has thought deeply about. Any conflicting ideas to discuss and aid in the development of these concepts would be greatly appreciated. Please feel free to share your thoughts or comments with rory@laplastecnica.co.nz.

ARMO2025 CONFERENCE

Hosted by StAR in New Delhi C E L A L B E Y S E L , F LO T E K S

In 2011, I asked Ravi Mehra, an ARM USA Hall of Fame member with Indian origin and longtime experience in Rotomolding, to come to Türkiye to discuss some technical issues about ROTOMOULDING with me and my company staff. His answer encouraged me to plan a visit to India, a totally unknown geography for me. “If you come to the StAR meeting and make a presentation, I will visit your company, as well,” Ravi replied.

At that time, I had already been using some Indian Rotomoulding machines for some 12 years and the reason for my choice was my Dutch friend and mentor, Roelf van der Wijk. Being a passionate ambassador of Rotomoulding, he had mentored an Indian company to build machines under a German license. For me, his word that Indians are reliable technicians to build quality machines was enough. So, I started buying the machines without seeing the

Indian producer and continued to do so for years. With Ravi encouraging me, I decided I owed myself a visit to India, and turned a StAR conference into a twoweek India visit with my wife and some friends.

I was already accustomed to attending ARM meetings in Canada, US, and various EU countries and making presentations. My first visit to India was a colorful surprise to us all. The technical side was strong, with valuable speakers

from all over the world, and socially there was a very warm welcome with perfect, colorful organization by the StAR staff and Indian colleagues from the Rotomolding Industry. After this first India experiment, I have become a permanent visitor of India, being present at all the StAR meetings.

I have a map of India in my office, with 17 pins on all the places I have visited in this incredible, colorful country. Once, an Indian customer, who visited my company accepted with astonishment that I have seen more of India than he has!

We all know and appreciate that Indians living in various developed countries are successful in various scientific areas and businesses, and this has been the case for

decades. Visiting India over the last 13 years continuously and comparing this country in 2012 and 2025, I can say that the local developments in infrastructure, roads, environment, hygiene, and human resources are immense.

As an appreciating outsider, I hope these developments will be permanent and India will not fall into the trap many developing countries seem to be falling into in our era: diverting its valuable resources to the diversionary actions and continuing the speedy development like the last two decades, for the wealth and health of its citizens.

2025 ARMO Meeting

Up to 2025, the StAR meetings over the past 13 years have been

held in various cities of India: New Delhi, Mumbai, Goa, Kerala, Kochi, Jaipur…to name a few.

The idea was to inspire visitors from around the world to explore India’s diverse cities and marvel at their breathtaking beauty, rich history, profound philosophy, vibrant culture, and timeless traditions. It was, without doubt, a perfect concept. To travel within India after the international flight was admittedly a bit daunting for some participants with limited time around the meeting dates.

In response to the feedback from potential attendees, the StAR Committee decided to host the meeting in Delhi. For those interested in sightseeing before or after the event, a recommended travel agency was made available

Senior StAR Board Members U Savadakar, RP Shukla, A Baheti, and S Dave Honor Ravi and Manju Mehra for their longtime leadership

to assist with tour arrangements.

For the spouses of the attendees, special Delhi tours were organized each day of the meeting.

Another key change was the timing of the meeting: this year, it was scheduled for the second week of February to avoid the frequent flight delays caused by the persistent fog that blankets Delhi airports during January mornings. This time, the Leela Ambience Convention Hotel was selected as the venue for ARMO 2025, offering exceptional facilities and the ability to meet the diverse needs of all guests.

However, there was one minor hiccup: the hotel’s full address was not provided on the ARMO 2025 website, leading to some confusion among attendees about which of the four Leela properties to direct their taxi drivers. A small oversight in an otherwise highly successful event.

The meeting commenced on February 12th with a series of

30 ROTOWORLD® ISSUE 1 • 2025

workshops, following the tradition of previous ARMO gatherings.

A large number of Indian and international rotomolders—eager to deepen their understanding of the complex technical aspects of rotational molding—actively participated. The workshops provided a rare opportunity to ask questions that participants might hesitate to pose in the presence of direct competitors. Subject-matter experts addressed these inquiries openly and graciously, fostering a collaborative and insightful atmosphere. Rotomolders who do not attend ARMO meetings undoubtedly miss out, as the knowledge and practical insights shared in these meetings can make a significant difference in both their professional growth and the success of their companies.

I can say without hesitation that StAR meetings compete with any rotational molding meeting throughout the world, as far as technical details are concerned.

The education program provided a wide array of important topics and discussion. From the emerging opportunities in India, sustainability, equipment and technology, business matters, and regional rotomolding updates, to product development. There was something of value for every attendee, which was underscored by the attendees’ comments both during and after the conference.

G. Raju, Welspun BAPL Rototech, India, talked about emerging opportunities in the Indian rotomolding industry. “India is poised to be the fastest-growing major economy over the next three years and the third largest globally by 2030,” he said.

Ahuja, Frontier Polymers, talked about rotomolding post-consumer recycle in India as a path to sustainability. “There is a global problem of pollution caused by post-consumer waste, which is an acute issue in India,” Martin Coles said. It serves to contaminate the soil and water, clog drains, and exacerbate landfill and plastics in the oceans, all causing health implications.” Celal Beysel, Floteks, shared his present and future thoughts on rotomoulding including developments in machinery and molds, prejudices about rotomoulding that need to be broken, and environmental issues concerning rotomoulding. demands, there have been major developments in the rotomolding industry.

Dr. Gareth McDowell. 493K, talked about cooling stage of the rotomolding process. “The cooling stage determines the final values of density throughout the wall of the part,” he said. This is important because the density is directly responsible for shrinkage and

warpage of the part. Dhanu Patell, Reinhardt Teknik, India, talked about how to make the operator’s life easier with efficiency, safety, and on a budget. “Today’s operator safety has become a top priority moving towards zero accidents and zero defects,” he said. Aldo Quaratino, Matrix Polymers, talked about how to mold efficiently and optimize the process using HDPE. He explained why the rotomolder needs to optimize, HDPE grades, and presented a case study on National Poly Industries (NPI).

Rajeev Sharma, Brilsol, covered traceability: shaping the future of rotational molding. Traceability is the tracking and tracing of products through the supply chain. Dominic Polayil, Welspun, BAPL Rototech, talked about good shop floor practices for World Class Quality. The customer expects quality, cost, delivery, design, and innovation. Ashish Baheti, Vectus Polymers, shared some winning tactics that can be used to skyrocket business.

“Valuation is a combination of the

art and science of determining a business’ worth, blending financial metrics with future potential to capture its intrinsic value.” Mohit Shukla, MPlast India, talked about developing a right to win! “A right to win is the ability to engage in any competitive market with a betterthan-even chance of success.

“Geopolitics is becoming more important than ever in our lifetime, in an inter-connected world.” Ronny Ervik, Norner, reported Norway has a population of 5.5 million, is the same size as Germany, has the 2nd longest coastline in the world, 80% of the population lives less than 10 km from the coastline, and the country has nine rotomolders.

“Extreme products over the next ten years will be required for extreme weather events, critical changes to earth systems, biodiversity, and ecosystem collapse, natural resource shortages, among others.”

Martin Spencer, UniqueRoto, talked achieving a successful product from effective idea generation, which is the

cornerstone of successful product development. Brainstorming allowing teams to generate a wide array of ideas. “Techniques such as mind mapping or the SCAMPER method can facilitate diverse thinking and inspire unique product concept.” Ian Hansen, Roto-Consult, gave his insights into the large storage tank market in Australia and New Zealand. Australasia has a relatively high percentage of companies rotomolding large storage tanks (1,000L to 50,000L).

While the main product application is for the storage of water, there are different applications suitable for large poly tanks, such as chemical storage, liquid fertilizer, silo tanks, cartage tanks, bunded diesel tanks, and water treatment tanks. Miki Burmil, Rotational Molding consultant, talked about manholes manufactured with rotational molding. He gave an overview of the current market for manholes, what they are used for, the advantages of using plastic manholes, manholes production, and a comparison of producing manholes with injection molding compared to rotational molding.

Regional Updates

There were many updates from various regions of the world presented by Regional ARMO Affiliates representatives and others in the industry. Graeme Hall, ARMA, identified key issues for the Oceania market as workforce shortages, slowing demand, and environmental impacts. The closure of Quenos in the region has left a significant gap in the supply of locally produced rotational molding grade resins, which has led to a transition to a full import model and some positive outcomes.

Professor Marek Szostak, Poznan University of Technology and President of Rotopol Association, reviewed the industry in Poland.

There are 74 rotomolders and a total of 107 in Eastern Europe.

The consumption of plastics in Poland in 2024 was 36% injection molding; 30% extrusion molding; and 2% rotational molding.

Maria Costa, Imerssa, Mexico, presented Market Trends and Future Prospects in the Mexican Rotomoulding Industry. The outlook indicates the rotomoulding market in Mexico is expected to continue to grow at a steady pace. A compound annual growth rate (CAGR) of 6% is projected specifically for sectors such as automotive, transportation, and warehousing.

Oliver Wandres, MAUS and President ARM-CE, talked about the ARM-CE Association in Central Europe. which was founded in 1998. Commonly produced rotomolded products for the region include commercial vehicles, agriculture construction, floor cleaning, medical waste harvesting energy defense water treatment, sanitation, furniture, lights, flowerpots, leisure, and playground equipment. Ravi Mehra filling in for David Smith, Muehlstein and ARMO Chairman, presented the evolution of the North American Rotomoulding industry. He reported ARM has seen 40% membership growth in the past 5 years. It has been in spite of a lot of consolidation with Tank Holding and Myers Industries adding to their portfolios to become North America’s two largest rotomoulding entities.

Martin Spencer, BPF Representative on ARMO Board,

gave an update on British Plastics Federation and rotomoulding activities. BPF was founded in 1933 and has over 500 members in aspects of the plastics industry.

Its mission focuses on promoting sustainability, innovation, and business growth within the sector.

The Rotomoulding Group was founded in 1978 and with 46 current members is a specialized division with the BPF that focusses on the specific needs and interests of rotomolders.

It provides guidance on best practices, technical standards, and fosters collaboration among its members. The UK Rotomoulding market has approximately 70-80 moulders, which demonstrates significant growth, fueled by increasing demand for sustainable and innovative plastic solutions.

The UK rotomoulding sector has seen significant advancements, particularly in sustainable practices and material technology companies are increasingly adopting eco-friendly resins, contributing to the reduction of carbon footprint in the industry.

Future trends indicate a growth in automation and digitization within the rotomoulding process, enhancing efficiency and quality.

There is also a notable shift toward recyclable materials and circular economy practices.

The Evolution Towards Hybrid and Electric Machines in a Changing Geopolitical and Energy Context ROTOMACHINERY.COM

The current geopolitical situation, with its repercussions on the energy market in terms of rising tariffs and threats to the availability of natural gas, combined with the growing environmental awareness, reflected in regulations that discourage the use of fossil fuels and instead promote renewable energy has posed a challenge for Polivinil Rotomachinery S.p.A., a leading company in the production of rotational molding machines traditionally powered by gas.

At present, the most reliable alternative to gas is the use of electric resistors, either as a replacement or in combination with the burner. Research in this field has yielded promising results, both in terms of original theoretical solutions (patent UR/SS/18697 ITAB, pending in Europe and other countries) and practical applications, with the launch of fully electric machines

36 ROTOWORLD® ISSUE 1 • 2025

(in the small to medium size range) and hybrid gas/electric models (for larger machines) at leading European customers.

The first step was to select the most suitable type of resistors available on the market for the process, those characterized by extremely fast heating to reach the temperature set, long-term resistance to high temperatures at full power, structural and design features suitable for installation in a convection oven equipped with a high-flow and high-pressure fan.

The space occupied by the resistors assembly and its positioning within the combustion chamber, required specific studies on airflow, aimed at ensuring optimal heat distribution inside the cooking chamber, while maximizing thermal exchange with the resistors. This was achieved by modulating the fan and adopting special deflectors.

The design intervention also included a deep evaluation of the fans, in terms of improving efficiency with increases in pressure (air speed) and flow rate (mass of hot air in circulation), even resulting in a notable reduction in electrical consumption.

The system’s efficiency was also validated in fully electric machines, where cycle times were comparable to those of traditional gas-powered machines of the same size.

One limiting factor is the high electrical power required to completely replace the burner, particularly in larger machines, where such power levels are often unavailable at the production site.

In these cases, hybrid machines are preferred, in which the burner operates at full capacity to bring the oven to the desired temperature and then gradually modulates down until it switches off completely, leaving the

resistors to maintain the setpoint.

As we will see, the resistors effectively contribute to achive faster the temperature setpoint, so, the cycle time and the productivity is faster.

The table presents a comparative data for a hybrid machine model PRM 3000- 3C, equipped with a 580 kW burner and 240 kW resistors, with a molding temperature at 250°C and a cooking cycle duration of 22 minutes. This cycle is used for molding a polyethylene bell for glass collection, with a height of 1,700 mm, a load of 27 kg, and a wall thickness of 4 mm.

The advantages in terms of reduced gas consumption and consequently the environmental impact are evident and have been verified by our customers who already use our hybrid machines.

Gas consumption and electrical absorption optimization is possible thanks to the software that modulates both the burner operation and the energy absorbed by the resistors.

In the presence of photovoltaic panels, the system is also able to limit the resistors’ energy consumption to the real-time production of the panels, where

the burner is used as support, to ensure the desired temperature is maintained, thanks to the excellent insulation of the oven and the action of the latest generation fans.

This patented operation perfectly complements the REGEN system, which equips the most advanced Rotomachinery Group machines. With REGEN, at the end of the cooking cycle, the fan is stopped in a very short time, minimizing heat loss when the doors open and generating regenerative electricity to be used back for the machine.

Our simulations have shown that the higher cost of the resistors can be amortized over a period of 5-6 years, using

appropriate photovoltaic panels.

The benefits are evident in terms of independence from external supply sources, especially in scenarios characterized by rising tariffs and reduced availability.

The decision to switch to fullelectric or hybrid machines is made together with the customer, starting, as always, from an analysis of the specific situation, considering the availability of electrical power, the presence and capacity of photovoltaic panels, and cycle data, particularly with regard to the combination of cooking phase duration and molding temperature.

Sustainability is a Strategic Advantage— Not a Regulatory Burden The Corporate Sustainability Reporting Directive (CSRD) marks a turning point in how companies across Europe report on environmental and social impact.

With the European Commission’s updated guidance as of February 26, 2025—narrowing its scope to businesses with over 1,000 employees—the directive remains a powerful force, not just in compliance but in opportunity.

Far from being a bureaucratic checkbox, the CSRD is a springboard for long-term value

creation. It places sustainability at the heart of strategy, urging companies to rethink how they operate, innovate, and grow. It’s a catalyst—not a constraint.

Sustainability as Strategy, Not Just Compliance

The European Union’s ambition to become the world’s first netzero continent by 2050 isn’t just about reducing carbon. It’s about building an economic ecosystem rooted in responsibility, resilience, and innovation. For businesses,

this represents an enormous opportunity.

Sustainability reporting under the CSRD enables companies to embed ESG (Environmental, Social, Governance) principles directly into their operations— from product development to supply chain management and digitalization. Doing so can reduce costs, attract investment, unlock innovation, and build a durable competitive edge.

At Matrix Polymers, we’ve embraced this shift. As leaders

in sustainable materials for the rotomoulding industry, we are not waiting to be compliant—we’re aiming to lead. We’ve pioneered the use of post-consumer recycled (PCR) waste in fully formulated materials for diverse applications, from industrial products and garden items to point-of-sale displays and indoor furniture.

Our approach is about more than compliance. It’s about turning sustainability into measurable business value—for us and our customers.

to invest in sustainability?” but rather, “Can we afford not to?”

A Call to Action: Make Sustainability Your Advantage

The Real ROI: Why Investing in Sustainability Pays Off

Overcoming Misconceptions, Delivering Performance

Despite the potential, many manufacturers remain hesitant.

PCR materials are often seen as more expensive, inconsistent, or difficult to integrate into existing processes. And while giving plastic a second life is a noble goal; the reality is complex.

The challenges of collecting, sorting, washing, and processing used plastic into consistent, high-performing material are significant. For rotomoulding applications, batch-to-batch consistency is essential—not only to meet quality standards but to maintain productivity and ensure product performance.

This is particularly critical in highvalue sectors like automotive and construction, where tolerance for material variability is low.

Another hurdle is perception.

Too often, recycled content is conflated with internal regrind from industrial scrap— material that may cut costs but compromise quality and durability. True PCR solutions demand rigorous testing and

Here’s why: • Competitive Differentiation ESG leaders attract ecoconscious consumers, responsible investors, and talent who want their work to matter.

• Innovation & Market Expansion Sustainable practices foster fresh thinking—opening new markets and driving product breakthroughs.

• Cost Savings & Operational Efficiency Sustainable operations often lead to energy savings, material efficiency, and reduced waste over time.

• Risk Management Proactive ESG strategies help

Sustainability is no longer an optional add-on—it’s a business imperative. The CSRD may compel compliance, but the real opportunity lies beyond the regulation. It’s a chance to lead.

At Matrix Polymers, we’re embedding ESG into the core of our business—not just to comply, but to compete, to innovate, and to shape a more sustainable future.

We’re not just preparing for the future—we’re helping build it.

Bud Boyce

A Legacy Cast in Innovation and Integrity C L A R K B O Y C E , G R E G S T R O M C O R P O R AT I O N

Alden “Bud” Boyce, a pioneer in the moldmaking and rotational molding industries (and my father) passed away at the age of 85 after a courageous battle with lung cancer. A longtime member and staunch supporter of the Association of Rotational Molders (ARM), Bud leaves behind a legacy defined by innovation, craftsmanship, and dedication to the advancement of the industry.

Bud began his career in 1957 at Superior Mold & Die in Munroe Falls, Ohio, where he worked as a machinist and rubber mold builder.

He soon transitioned to Roto Matic, where his mechanical aptitude helped him contribute to the design of rotational molding machines—earning several patents in the process. This work introduced him to the burgeoning rotomolding sector, which would become the centerpiece of his professional life.

Recognizing the growing need for high-quality molds to match the evolving machinery, Bud continued his journey with Roto Mold & Die in Cuyahoga Falls and later with Industrial Artcraft in Akron. There he met John Wheeler, and in 1975, the two co-founded Wheeler Boyce

46 ROTOWORLD® ISSUE 1 • 2025

Company in Tallmadge, Ohio. The small start-up quickly gained a reputation for excellence and grew into a 100,000-square-foot operation in Stow, Ohio—Bud’s hometown—serving customers around the globe.

Wheeler Boyce Company emerged as one of the leading rotational mold makers in the world. Under Bud’s leadership, the company earned the ARM Distinguished Service Award, and Bud himself was inducted into the Rotational Molding Hall of Fame.

His contributions to thin-walled cast mold production, equipment development, and manufacturing

process improvements remain in use today.

Although Wheeler Boyce initially focused on cast injection molds—particularly for major customers such as Brown Shoe Company—the company pivoted toward rotational molding when global manufacturing trends shifted. Bud led this transition with strategic vision, positioning the company at the forefront of the industry and deepening his involvement with ARM and its global community.

Those who worked with Bud remember not only his engineering expertise, but also his relentless commitment to precision and cleanliness. Bud believed that an organized workspace reflected a professional mindset. Whether it was his home workshop or the company foundry, everything had a place—and it was kept there. The Wheeler Boyce facility became known in the industry for its meticulous cleanliness, even within the challenging environment of sand casting.

Visitors often remarked on how clean the operation was— something that was never the result of last-minute preparations, but rather the product of an

ingrained, daily standard.

Bud officially retired in 2006, selling the company and relocating to Maryland with his wife, Sharyn. Yet even in retirement, his conversations frequently returned to rotational molding—its developments, challenges, and people. Bud remained deeply connected to the industry and proud of the role he played in its growth.

He is survived by his wife, four children—Gary, Terry, Sherry, and Clark—four stepdaughters, 15 grandchildren, and 8 greatgrandchildren.

Bud’s legacy extends beyond his technical achievements.

He shaped a culture of pride, professionalism, and camaraderie in the mold-making and rotomolding communities.

He treasured the friendships forged over decades of ARM events, plant tours, and problemsolving sessions. His curiosity never waned; he had a habit of examining any plastic product

he came across to see if it might have been rotomolded—and if so, by whom. His passion was evident in every part, every conversation, and every project.

Bud Boyce leaves behind a respected name, a thriving industry he helped shape, and a generation of professionals inspired by his standards. His impact on rotational molding is lasting and measurable—not only in molds and machines, but in the people, he mentored and the values he instilled.

The industry is better for having had him. And though he’s no longer walking shop floors or studying plastic parts in the wild, his influence continues. Rest well, Bud—we’ll carry it forward from here. R

Some years later my father purchased his partner’s part, and the company became a 100% Mexican family owned. I have played different roles within the company, and when my father retired approximately 26 years ago, I became CEO. I also serve as President of the Board.

Llevo más de 30 años trabajando en Grupo Miraplástek. La empresa la fundó mi papá en asociación con un estadounidense, sin embargo unos años después le compró su parte al socio, convirtiéndose en una empresa familiar con capital 100% mexicano. A lo largo de los años he desempeñado diversos roles dentro del grupo y, después de la jubilación de mi padre, hace aproximadamente 26 años, me convertí en CEO, puesto que mantengo a la fecha. Además, actualmente soy presidente del Consejo de Administración.

Q: What is your work and educational background prior to your current role? Tell us about your first job.

A: I am a computer engineer, so my first jobs were developing software systems for several clients. Then,

www.rotoworldmag.com 49

I developed the sales system for Miraplástek as a freelancer. It was after that I asked for a fixed position and was hired to open a sales office in Mexico City. I grew up hearing my father talk about rotomolding and I used to go to ARM meetings as a stowaway.

However, when I finally started working in the company, I realized I really didn’t know enough to be part of the industry. I needed to learn and one of my first training events was attending Glenn Beall’s Introduction to Rotomolding, and I still remember how tired I was when I finished that day!

Soy ingeniero en sistemas computacionales y mis primeros trabajos fueron desarrollando sistemas de software para varios clientes. Al principio desarrollé el sistema de ventas para Miraplástek como freelance y eventualmente pedí un trabajo fijo, en el que comencé abriendo la primer oficina en Ciudad de México. Toda la vida escuché a mi papá hablar sobre rotomoldeo y siempre iba a las reuniones del ARM como polizón, sin embargo, cuando finalmente comencé a trabajar de lleno en la empresa, me di cuenta de que en realidad no conocía lo suficiente como para ser parte de la industria. Uno de mis primeros entrenamientos fue el curso de Introducción al Rotomoldeo de Glenn Beall, todavía recuerdo lo exhausta que terminé ese día.

Q: Tell us about the family you grew up in and highlight the role of your father and his career in the rotomolding industry.

A: My family was very united. It was my late father, José Miranda; my mom, Conchita (who is in very good shape and just celebrating her

50 ROTOWORLD® ISSUE 1 • 2025

80th birthday), my younger brother, José, and myself. My father was working in the plastics industry almost since he began working, even though he was educated as a Civil Engineer. He met Rush Smith, a veteran rotomolder in the states, and got involved with what became his passion, rotational molding. He enjoyed the process, the creation of new products, and the challenge of selling in a market that was new for the process.

Mi familia siempre fue muy unida; mi papá, José Miranda, mi mamá, Conchita (que acaba de cumplir 80 años y está en perfecta salud), mi hermano José Ernesto y yo. Aunque mi padre estudió ingeniería civil, en realidad estuvo involucrado en la industria del plástico desde el inicio de su vida laboral. Conoció a Rush Smith, un veterano rotomoldeador, y este le presentó lo que luego se convertiría en su pasión, el

rotomoldeo. Siempre disfrutó del proceso en sí mismo, del desarrollo de nuevos productos y del reto que significaba vender en un mercado en el que el proceso era completamente nuevo.

Q: Tell us about your immediate family—your husband and children, who they are and what are they doing? Do you see any of your children following in your footsteps?

A: I met my husband, Roberto, when he pursued selling us some products, so for the record, I live with a customer, since we got married in 1997. We have three children: Ariana, who is a lawyer, married, and mother of my two incredible grandsons (Jerónimo and José Andrés); Roberto, who is a passionate marketing guy; and Alejandra, who is still studying architecture. For now, I don’t think they want to run the company,

however, they love it and feel very involved with it.

Conocí a mi esposo, Roberto, porque nos buscó para que le vendiéramos algunos productos, así que sí, vivo con un cliente desde que nos casamos en 1997.

Tenemos tres hijos: Ariana, que es abogada, está casada y es mamá de mis dos increíbles nietos (Jerónimo y José Andrés), Roberto, que es emprendedor y apasionado del marketing, y Alejandra, que está estudiando arquitectura y lo disfruta muchísimo. Por lo pronto, no creo que quieran dirigir la empresa, sin embargo, sé que les encanta y siempre están muy involucrados.

Q: How would you describe the Roto industry, its importance, and its impact on businesses and consumers.

A: The Roto industry is very special. It is a small part of the

global plastic industry, but it is an example to everyone else of a united, collaborative, and cohesive group that feels like a family. I have friends all over the world, and I know I can rely on them as they can me and my company. I think I have the same passion my father had for the industry and the industry’s association (Association Rotational Molders). For our customers, rotomolded products are their best choice for a very wide variety of uses, and normally they will find in us a committed supplier that will do their best to provide a quality product and a good service.

La industria del rotomoldeo es muy especial, aunque es una pequeña parte del mundo del plástico, es un ejemplo de un grupo unido, colaborativo y coherente que se siente como una familia.

Tengo amigos de todas partes del mundo, y sé que cuento con ellos

tanto como ellos cuentan conmigo y mi empresa. Creo que comparto la misma pasión de mi papá por esta industria y por la asociación.

Para los clientes, los productos rotomoldeados definitivamente son la mejor opción para una amplia variedad de usos y en nosotros encontrarán un proveedor comprometido que hará lo mejor por darles un producto de la más alta calidad y un excelente servicio.

Q: Most would agree the Roto industry is a male-dominated industry, and as such what do you perceive as the biggest obstacles for a woman who is running a rotational molding business? Or any manufacturing business for that matter?

A: Rotational Molding is definitely a male-dominated industry, and even more so in past years. After years and years of being almost the only woman rotomolder in the room, thanks to some female suppliers, I am not the only woman these days. It was nice when we used to dance at the Galas, because I have never been more popular in my life! In recent years, things have changed little by little, we now have women in different positions, both on the rotomolder and the supplier sides. This makes me very happy, because I am convinced that we, men and women, complement one another very well to make better decisions, to have a complete view of the problems. Running the company, with a big majority of male collaborators, has been a challenge, but not a problem.

When I began, my father was there, and all the players have known me since I was a kid. I grew up in that space. Then, I think I earned respect from them by being responsible and collaborative.

www.rotoworldmag.com 51

El moldeo rotacional es definitivamente una industria dominada por hombres, sin embargo hace algunos años lo era mucho más. Años y años de ser la única mujer rotomoldeadora en la sala... Gracias a algunas proveedoras, no la única mujer.

Por un lado era bueno cuando bailábamos en las galas, ¡nunca me he sentido más popular en mi vida! Poco a poco las cosas han ido cambiando en los últimos años, ahora tenemos a mujeres en diferentes puestos, tanto del lado de los proveedores como de los rotomoldeadores. Esto me encanta, porque estoy convencida de que los hombres y las mujeres nos complementamos para tomar mejores decisiones y tener perspectivas más completas de los problemas. Para mí, dirigir una compañía en donde la mayoría de los colaboradores son hombres ha sido un reto pero nunca un problema. En un principio, mi papá estuvo ahí y todos los demás en la industria me conocieron desde que era niña, crecí en ese ambiente pero creo que después me gané su respeto siendo responsable y colaborando con ellos.

Q: What was your father’s management style and core business philosophy? What is yours? What do you see as the differences in the business back then and now?

A: My father was very strict and demanding in his early days. He softened a little bit over the years but was always the big boss. I began working as one of the team, so I feel that my style was more democratic and now, I think I operate more like an encouraging leader of my team. The new challenge is working with four

52 ROTOWORLD® ISSUE 1 • 2025

generations, we still have some baby boomers, a small group of Gen X, lots of millennials, and now a new growing group of very young Gen Z, who are very techy. We are experiencing very fast changes in technology, and these new ways of working are sometimes a bigger challenge than the people are.

Mi padre fue muy estricto y exigente al principio, el pasar de los años lo suavizó un poco pero siempre fue el gran jefe. Por otro lado, yo empecé como un miembro más del equipo, así que siento que mi estilo en un inicio fue mucho más democrático y ahora creo que he evolucionado a ser una líder más motivadora. El nuevo reto es trabajar con cuatro generaciones, aún hay algunos baby-boomers, un grupo pequeño de Gen X, muchísimos millennials y un grupo creciente de Gen Z, quienes son muy tecnológicos.

Estamos viviendo muchos cambios en materia de tecnología y a veces esas formas nuevas de trabajar son mayor reto que la misma gente.

Q: How would you describe the Roto industry in Mexico? What are the core products manufactured there? How competitive is it? Do you see the industry in Mexico growing and developing? Do you have any statistics you can share regarding the number of rotomolders in Mexico or rates industry growth in that region of the world?

A: The main product in Mexico is water tanks (tinacos), for domestic use. We have hundreds of open flame producers doing only tinacos. We also have some very big, specialized companies that rotomold water tanks in a more professional way. And there is small but growing group of

companies that rotomold products with more added value from flowerpots and traffic barriers to very complex crosslink tanks. I think in Miraplástek we cover the spectrum of parts being molded in Mexico. The market is learning the advantages of rotomolded parts and there is a nice opportunity to convert a lot of products that are not currently made in polyethylene or similar materials to nice highquality rotomolded products.

El principal producto en México definitivamente son los tinacos o tanques de agua para uso doméstico. Hay cientos de rotomoldeadores de flama abierta que solamente producen tinacos aunque también hay algunas empresas grandes especializadas en producir tinacos de manera más profesional. Existe también un pequeño, pero creciente, grupo de compañías que ofrecen productos más especializados, desde macetas y vallas de tránsito hasta complejos tanques de crosslink. Creo que en Miraplástek cubrimos con el espectro completo de lo que se fabrica en México. El mercado está descubriendo las ventajas de usar piezas rotomoldeadas por lo que existe una gran oportunidad de cambiar algunos componentes que actualmente no son de polietileno o materiales similares por unos lindos productos rotomoldeados de gran calidad.

Q: In your experience are there things you feel are foundational to surviving in the Roto industry?

Are there things you see as foundational to thriving?

A: For us, it has been designing and making our own molds that has given us a big advantage. We also design and make molds for other rotomolders. I am very proud of

that part of the company. I think we have a very good professional team.

Para nosotros, el diseñar y fabricar nuestros propios moldes ha significado una gran ventaja.

Incluso fabricamos moldes para otros rotomoldeadores. Estoy especialmente orgullosa de esa parte de la empresa, creo que tenemos a un equipo sumamente profesional.

Q: Are there any lessons learned along the way you can share with our readers in your woman-owned and -operated business?

A: It would be unfair to say that I have had problems by being a woman in the industry. I have to say that maybe it has been an advantage. I have a lot of male friends with whom I have worked with as a customer, supplier, association mate, and board member. I have learned to work with each of them and I feel very comfortable with it. Maybe my best advise now that things have changed for a lot for us, would be to forget about genders and focus on capabilities. With that said, I am pleased to see the growing numbers of women assuming positions in rotomolding throughout the world and we’ll be focused on highlighting some amazing work women are doing in our space.

Sería injusto decir que yo he tenido problemas en la industria por ser mujer, tengo que decir que tal vez hasta ha sido una ventaja. Tengo varios amigos con los que he trabajado como cliente, proveedora, compañera en la asociación y en el Board y me siento muy cómoda con ello.

Quizás mi mejor consejo ahora que las cosas están cambiando es

que nos olvidemos de ver géneros y nos enfoquemos en habilidades.

Dicho lo anterior, estoy sumamente contenta y orgullosa con el trabajo increíble que las mujeres han estado haciendo dentro de la industria.

Q: What keeps you up at night?

A: Nothing in the world. I sleep like a baby. My problem is waking up!

Nada en el mundo, duermo como un bebé. ¡¡El problema es despertar!

Q: What are your passions in life, and why? What inspires you the most?

A: I am a family woman. My family, all of them, are what inspire me. But my second passion is Miraplástek for sure. I feel like they are my family too. I want to leave this world a little better than how it was before I came, so I try to help, support, and encourage the people

Q: What civic, community, and philanthropic endeavors are you involved in?

A: I serve in a community diner for children with high necessities for food, education, and care.

I have worked with a group of friends to maintain this place and in changing lives now for 15 years. I am very proud of BIFAM Aguascalientes and the more than 700 hundred children we have

near me and those who don’t know me but have heard about me.

Soy una mujer de familia. Mi familia, todos ellos, son los que me inspiran. Pero mi segunda pasión es Miraplástek, sin duda. Siento que ellos también son mi familia.

Quiero dejar este mundo un poco mejor de lo que era antes de venir, así que trato de ayudar, apoyar y animar a las personas cercanas a mí y también a aquellos que no me conocen, pero han oído hablar de mí.

attended over these years. I also participate in several boards, from banks to universities and others. My latest position is as a board member of CADERR that is an advisor committee of 15 businesspeople for the President of Mexico, Claudia Sheinbaum.

It has been a very interesting and challenging endeavor, and I plan to do my best to help my country grow and have better opportunities for the Mexican people.

Tengo un comedor comunitario para niños con altas necesidades en alimentación, educación y cuidado. He trabajado con un grupo de amigas para mantener este lugar y cambiar vidas durante 15 años. Estoy muy orgullosa de BIFAM Aguascalientes y de los más de 700 niños que hemos atendido en estos años. También participo en varios consejos de administración, desde bancos hasta universidades y otros. Mi último cargo es como miembro de CADERR que es un comité asesor de 15 empresarios para la presidenta de México, Claudia Sheinbaum. Ha sido un reto muy interesante y desafiante y planeo hacer todo lo posible para ayudar a mi país a crecer y tener mejores oportunidades para los mexicanos.

Q: If you were writing your own life’s story, how would you describe your journey in the roto business and industry?

A: My journey in rotomolding has been fascinating, a very interesting adventure that has made me happy and made me proud of what I have achieved both in my company and in the industry. Being inducted to the Hall of Fame is one of the greatest honors of my life. I hope to be remembered as one of the female pioneers of the industry, who always tried to participate and collaborate with my colleagues in making this industry better. In my company, I would love to be remembered as someone who really cared about her employees, her community, and her customers, giving always the best of me and never giving up in difficult times.

Mi trayectoria en el rotomoldeo ha sido fascinante, una aventura muy interesante que me ha hecho feliz y me siento orgullosa de

54 ROTOWORLD® ISSUE 1 • 2025

lo que he logrado tanto en mi empresa como en la industria. Ser incluida en el Salón de la Fama es uno de los mayores honores de mi vida. Espero ser recordada como una de las mujeres pioneras de la industria, que siempre trató de participar y colaborar con mis colegas para mejorar esta industria. En mi empresa, me encantaría ser recordada como alguien que realmente se preocupaba por sus empleados, su comunidad y sus clientes, dando siempre lo mejor de mí y sin rendirme nunca en los momentos difíciles.

Q: Are there specific roles you see women suited for in Roto?

A: I think women can play whatever role they want to in roto. Women should choose positions they are good at and like the most. Of course, there are some areas I recommend as very good positions for women due to their strong capabilities such as design, finishing parts, research, quality, HR, and of course direction!

Creo que podemos jugar el papel que queramos. Aquellos por lo que somos buenas o nos gusta más. Por supuesto que hay algunos que recomiendo como muy buenos puestos para aprovechar las capacidades de las mujeres, como diseño, acabado de piezas, investigación, calidad, RRHH y por supuesto, dirección!

Conchita Miranda’s journey from a local business leader to an international industry figure exemplifies her dedication to innovation, inclusive leadership, and economic development, making her a significant contributor to both her community and the broader manufacturing sector.

In closing, Conchita Miranda

is a leader worthy of admiration.

Throughout the years, she has proven to be a steadfast advocate for small and medium-sized businesses—not just within her own industry, but across a broader economic landscape.

She consistently champions the importance of supportive policies that foster innovation, drive competitiveness, and contribute to long-term success in every endeavor she undertakes. Beyond her professional accomplishments, Conchita has also mastered the balance between work and family life, firmly believing that the strength of family and community plays a vital role in achieving lasting business success.

La evolución de Conchita Miranda de empresaria local hasta figura internacional de la industria ejemplifica su dedicación por la innovación, liderazgo inclusivo y desarrollo económico, convirtiéndola en un miembro que contribuye en su comunidad y con un espectro más amplio del sector manufacturero.

Para concluir, Conchita Miranda es una líder digna de admiración. A través de los años ha demostrado ser una defensora de las pequeñas y medianas empresas, no solo dentro de su industria, sino en general en el mundo empresarial.

Constantemente defiende la importancia de políticas que impulsen la innovación y la sana competencia, contribuye en el éxito a largo plazo de todos los proyectos en los que se involucra. Además de sus éxitos profesionales, Conchita también ha logrado un balance entre el trabajo y su familia, con una fuerte convicción de la fortaleza de la familia y la comunidad juegan un rol primordial en el éxito laboral a largo plazo.

DISARMING DIVERSITY In today’s highly charged sociopolitical climate, privateand public-sector initiatives on Diversity, Equity & Inclusion (DEI) have come under increased scrutiny, and in many recent instances, have been outright halted. While supporters of DEI workplace practices hail their benefits, including a more inclusive, collaborative work environment that drives innovation and performance, critics deride these initiatives as unnecessary, feel-good, and even discriminatory activities that contrast with their

stated desire for merit-based workplace rewards and pathways to career advancement.

Irrespective of one’s views on DEI, a compelling body of evidence suggests that organizations that implement and remain committed to diversity initiatives demonstrate enhanced performance compared to organizations that eschew or have done away with these initiatives. As such, though highly controversial and polarizing, perhaps an objective examination of workplace diversity and its potential to drive organizational

performance is in order.

Note that this is not an attempt at a covert political statement, nor an endorsement of DEI initiatives per se; rather an attempt to objectively consider the potential business benefits of espousing a diverse, inclusive workplace environment, to include both outside-our-industry perspective as well as anecdotal evidence of its potential benefits within the rotomolding community.

What Are DEI Initiatives?

A generally accepted definition

www.rotoworldmag.com 55

X - FA C T O R

of DEI is “organizational frameworks that seek to promote the fair treatment of all people, particularly groups who have historically been underrepresented or subject to discrimination of disability.”

In other words, organizations embracing DEI acknowledge historical and structural challenges that have made career advancement more challenging for underrepresented groups defined by various criteria, such as age, ethnicity, disability, gender, and sexual orientation.

Put into practice, several common and readily implemented initiatives include unbiased recruiting and hiring practices, inclusive leadership training (in addition to typical leadership training, focusing on cultural awareness, empathy, listening skills, support of diverse perspectives, etc.), employee resources groups (i.e. employeeled groups that seek to foster a sense of community and involvement, etc.), flexible work arrangements, and financial planning and wellness, among others.

But as critics will question, beyond the “feel-good” aspect of these initiatives, what measurable, tangible benefits to a business bottom line do diversity initiatives generate? Again, according to a number of sources, the answer appears to be “plenty!”

Mckinsey & Company: “Diversity Matters Even More”

Outside of our industry, let’s consider the case of global consulting giant, McKinsey & Company, which operates in 133 cities throughout the world and employs 45,000 who drove $16 B 56 ROTOWORLD® ISSUE 1 • 2025

in annual revenues in 2023. That same year, following its previous Diversity Matters reports from 2015, 2018, and 2020, in its 2023 Diversity Matters Even More report, McKinsey Global Managing Partner, Bob Sternfels stated: “some have asked whether we will continue to prioritize diversity in our meritocracy. The answer is yes. We will continue to boldly pursue both, because these two things together — our diverse meritocracy — is what makes us

their bottom-quartile peers; this year (2023), that figure hits 39 percent.”

Though impossible to directly connect the dots, perhaps the recent examples of retail giants Target and Costco lend credence to McKinsey’s findings. While both companies faced intense political pressure to roll back their commitment to DEI, only Target chose to do so, and appears to be facing adverse consequences as a result: according to the consumer

“ORGANIZATIONAL FRAMEWORKS THAT SEEK TO PROMOTE THE FAIR TREATMENT OF ALL PEOPLE, PARTICULARLY GROUPS WHO HAVE HISTORICALLY BEEN UNDERREPRESENTED OR SUBJECT TO DISCRIMINATION OF DISABILITY.” distinctive and has defined who we are over our nearly 100 years,” Among customers for whom McKinsey delivers consulting services, their data demonstrates that organizations who actively promote and implement executivelevel diversification initiatives - in particular, involving women and ethnic diversity representation in executive-level roles - outperform those organizations who don’t, and this trend is intensifying. Per McKinsey, “in each of our reports, 2015, 2018, 2020, and now 2023…the likelihood of financial outperformance gap (between those organizations purposefully implementing diversification initiatives and those who are not) has grown: Our 2015 report found top-quartile companies had a 15 percent greater likelihood of financial outperformance versus

analytics firm Numerator, in the four weeks ending February 9, 2025, Target saw a decrease in in-store traffic by 4.9 million visitors. By contrast, Costco’s in-store visitor traffic increased by 7.7 million during this same timeframe.

What Does this Mean for the Rotomolding Industry?

Following a cursory and unscientific review of industry websites and “Who We Are” content, it appears that very few companies in the rotomolding sector include “diversity” or DEI initiatives among corporate values or organizational charters. While unsurprising, I find this perhaps a bit confusing, particularly considering the prevalence of ethnically diverse workforces within many rotomolding

X - FA C T O R

manufacturing operations. Though defining specific workplace diversity initiatives to drive enhanced performance is fodder for another discussion, it would seem logical that any earnest attempt to do so would likely pay dividends.

In this light, let’s consider the anecdotal case of my previous leadership role with a metal fabrication business outside the rotomolding realm.

Oversimplifying in the interest of brevity, the organization, though predominantly of Latinx ethnicity, was significantly underrepresented – from both ethnic and gender perspectives – in manufacturing leadership roles.

However, as a cross-cultural and -functional team was assembled to articulate corporate values, this team unanimously adopted the value “Embrace Diversity” to address this under-representation and as a lever to attain business growth and expansion objectives.

Fast-forwarding to the adoption of “Embrace Diversity” as a corporate value and addressing the diversity disparity in leadership roles (particularly, increasing the number of Latinx women in these roles!), the organization was much better positioned to capitalize on business opportunities, driving attainment of strategic imperatives including establishing a second manufacturing site, implementing a powder coating line and robotic automation, and as a result of these enhanced capabilities and capacity, increasing revenues by 40%, all of which was accomplished over a two-year period.

OK, I realize I haven’t answered the “what does this mean for the rotomolding industry” question,

but I truly believe we have a real opportunity to better engage our increasingly ethnically diverse workforces - dare I say it, to embrace diversity – not as a feel-good exercise, but to drive tangible improvement in organizational performance.

Without question, the strategic objectives attained at the metal fabrication business could not have been realized without the improved communication, enhanced competence of manufacturing leadership, giving

anomalous value as a driver of organizational performance.

Instead, and given today’s super-charged sociopolitical climate, the company’s leader understandably declined to be interviewed for the article and requested that no mention of the organization be included. Of course, I will honor this request and respect and understand the rationale behind it.

At the same time, perhaps as more organizations eschew the potential political implications of

“I TRULY BELIEVE WE HAVE A REAL OPPORTUNITY TO BETTER ENGAGE OUR INCREASINGLY ETHNICALLY DIVERSE WORKFORCES - DARE I SAY IT, TO EMBRACE DIVERSITY – NOT AS A FEEL-GOOD EXERCISE, BUT TO DRIVE TANGIBLE IMPROVEMENT IN ORGANIZATIONAL PERFORMANCE.” a voice to all employees to offer ideas for improvement, etc. that the “Embrace Diversity” corporate value encouraged and required us to do. Again, I must believe this same opportunity exists for us in the rotomolding realm.

embracing diversity and instead focus on the practical and performance-driving benefits thereof, they, too, will realize the same level of growth, innovation, and success as our anonymous industry trailblazer. R

Moving from the Political to the Practical

In closing, I’m compelled to reference a recent conversation with the organizational leader of a rapidly growing, innovative and forward-looking company in our industry. As I happened upon this company’s mention of diversityrelated language among its corporate values, my initial intent was to focus this article on how the company is leveraging this www.rotoworldmag.com 57

ARM Executive Forum Reflections and Insights from Scottsdale JENNIFER GIBSON HEBERT

I am delighted to write about the 2025 ARM Executive Forum that recently took place in Scottsdale, Arizona. The Forums and Programs Committee, led by Conchita Miranda, curated a powerful blend of industry insights and expertled sessions that delivered real value to attendees. Topics ranged from the shifting macroeconomic landscape and cybersecurity to sustainability, workforce alignment, and intellectual property protection.

The forum wasn’t all business, of course. Attendees also enjoyed golf, a desert jeep tour, and even a little friendly competition on the pickleball courts. My personal highlight was trying pickleball for the first time—even in the 95-degree Arizona heat! It was a fun and memorable way to connect with peers. (And to Pat Long, Matt Bushman, and Carsten Erkel—my sincere apologies for my 0–4 record.)

Driving Business Value in Today’s Economy

Alex Chausovsky, Bundy Group, presented a macroeconomic update, leading indicator input labor market data, and gave some actionable takeaways. The world economy in 2025 is $115 trillion with US GDP at 26.3%, the EU at 17.3%, and China at 16.9%. The GOP trifecta in holding the Presidency, Senate, and House has ushered in a new era of geopolitics. “The US holds trade deficits with most

countries,” he said. Businesses can reduce tariff liability by using the first purchase price rather than the final resale price, which requires accurate documentation and compliance with US Customs and Boarder Protection regulations to benefit from lower values.

Bonded warehouses also allow you to store good without paying duties until they are used or sold, deferring duty payments and significant cash flow benefits.

Chausovsky broke down the US economy GDP components as 17% government spending, 17% business investment, and 66% personal consumption. “Retail activity remains positive, but debtto-income ratio is declining. The labor market as of February 2025, job gain was 151K, unemployment at 4.1%, and hourly earnings increased by 4.0%. The new normal higher consumer prices are up by

3.3%. As of February, the national labor market showed 151K in job gain, 4.1% unemployment, and 4.0% average hourly earnings over the past 12 months. “The share of the population 65 and older is projected to continue rising, and without immigration, working-age

people will start to disappear from the US labor force.” he said.

Plastics and Manufacturing in 2025

The United States remains the dominant player in the global economy. China follows, although its self-reported 4.5% GDP growth is widely believed to be closer to 2–2.5%, mirroring U.S. performance.

China’s long-term demographic decline—stemming from the onechild policy—is now constraining economic growth. Perc Pineda, Chief Economist, Plastics, reported a positive US economy regarding its real economic output and potential output (2000-2024). The industry’s challenges remain inflationary constraints, labor shortages, and monetary policy response. Of the 12 countries leading exports and imports, China leads in exports by 14.3% and U.S. leads in imports by 13.2%. “Rotomolded plastics manufacturing outlook indicates Leisure projects +2.4%, construction residential +18% (non-residential +2.2%), industrial production manufacturing +,06%, Automotive Motor Vehicles Production 1.8% (light vehicle +2.7%, and agriculture +2.7% (202025),” Pineda said. “For the plastics industry, the world is out market.

We thrive on fair trade, and with well-crafted trade agreements we will achieve better business results for all,” Pineda said.

The U.S. remains relatively selfsufficient in trade, ranking 56th globally in trade dependence.

However, high tariffs enacted in recent years have disrupted industry dynamics. The plastics sector has voiced concerns over retaliatory tariffs from Canada and the EU. With the U.S.-MexicoCanada Agreement (USMCA) due

for renegotiation in 2026, trade policy remains an important watchpoint.

His top recommendations: if you are facing a threat are: • Freeze your credit with all major bureaus (free to do)

Sustainability and Circular Design

Sustainability was a central theme throughout the forum. Kenneth Carter, John Deere, highlighted major strides in incorporating recycled materials, improving fuel efficiency, and embracing designfor-the-environment principles.

While Europe leads in sustainable manufacturing standards, the U.S. is beginning to follow, with growing emphasis in the automotive and industrial sectors.

They will accomplish this through sustainable and recyclable content, reducing operational greenhouse gas emissions, and reducing upstream emissions,” he said.

Adam Covington, Ferry Industries, detailed how to create a company specific SOP on each of these processes. “Safety is a continuous improvement process,” Covington said. Preventative maintenance may avert risk to personnel and property - an ounce of prevention is worth a pound of cure. Routine assessments of work cell risks and actions taken builds trust and positive results with stakeholders.

Training Culture

Establishing an optimal training culture was the topic for Jeremy Willliams, COO, and Melisa Derheim, HR Director for API. Key components include leadership commitment, continuous learning mindset, training plans specific to your culture, integration with daily operations, and continuous improvements. “One key factor to developing a successful training module is knowing your audience.

Looking Forward

According to ARM presenters, China is projected to grow its plastics production capacity by 41% by 2027, compared to 12% in the U.S. and 7% in India.

Maintaining competitive footing will require increased efficiency, innovation, and sustainable practices. Forecasts for the rest of 2025 suggest zero growth in Q2 and a moderate 1.9% rebound in the second half. Sectors like data centers and electric vehicles (projected to grow 8.4%) offer pockets of opportunity. Interest rates remain the primary variable affecting investment decisions.

Thanks to all who participated— your engagement, ideas, and energy continue to move our industry forward. I look forward to the year ahead and to continuing the important conversations that began in Scottsdale.

Be sure to book your attendance at the upcoming 2025 ARM Annual Meeting to take place September 29 - October 1 at the Hilton Anatole in Dallas, Texas.

P.S. I will never forget my first WAYMO experience of toodling around Scottsdale... R

ROTO AROUND THE WORLD

A ROTOMOLDERS

IAN HANSEN RotaConsult

JOURNEY TO THAILAND Ricky stood in his factory, staring at a row of rotomoulded products.

Some were in good condition, smoothly trimmed parting lines, even wall thickness, consistent colour shade — but others bore telltale flaws: blowholes, warping, and excessive surface porosity. He inwardly sighed. His business had grown steadily over the years, but as demand increased, so did the pressure to deliver on time with consistent quality. The occasional defects were costing him time, money, and sometimes customers.

At the beginning of 2025, while scrolling through industry updates, Ricky came across a promotional advertisement for a Rotomoulding Training Seminar being provided at the biennial Bangkok Trade Expo organised by TechnoBiz. This year sponsored by

Rising Sun Rotomolding Machinery and inclusive of intensive training seminars. The event promised to teach basic tank design, manufacturing and quality control techniques, raw materials knowledge, troubleshooting methods, and best practices to operate a rotomoulding businesses.

At first, he hesitated to take any action. Ricky was already overloaded and stretched too thin managing his rotomoulding business. Spending time away from the workplace felt risky for himself and his key rotomoulding staff. Ricky and his staff were already trying to do too many things at once, which was resulting in many of them not being done well. However, as he spent more time thinking about

the training seminar Ricky kept thinking of the potential benefits.

He decided to throw caution to the wind. Ricky thought, if this could help improve my business, even a little, it will be worth both the time away from his business and money to attend the seminar.

Education is the passport to the future, and attendance is the stamp that gets you there.

The 3-day rotomoulding training seminar required an investment of USD850/person to register.

As the seminar was in Bangkok, he had an international flight to Thailand and pay for hotel accommodation for at least four nights. A much greater investment than if the seminar was held in his own country. To help offset the financial investment, Ricky was able to obtain a

special registration discount of 25% after contacting the Expo sponsor, Rising Sun Rotomolding machinery. Ricky also decided to bring two of his key team members with him and obtained an additional 15% discount for the 3 registrations. Ricky thought of the famous quote often attributed to Einstein — “Insanity: doing the same thing over and over again and expecting different outcomes.”

Once Ricky focused on the benefits of training, the investment in both time and money was an easy justification.

Southeast Asia is composed of eleven countries of impressive diversity in religion, culture, and language. A major challenge for rotomoulders like Ricky is access to quality rotomoulding knowledge.

While the official languages in countries like Indonesia, Malaysia, Philippines, Thailand, TimorLeste, and Vietnam are different, English is widely used in business and is seen as a crucial skill for both international business and technical communication.

Managers and technically trained staff in Southeast Asia, especially

Rotomoulding conference & training program

the younger age group, are often multi-lingual. Many can communicate in three or more languages!

Ricky was typical of many of the international attendees at the training seminar. While he was able to speak English, his ability to understand spoken English (and read English words) was

much better.

The training seminars were held concurrently with the Trade Expo, in a separate conference room, within the Bangkok International Trade and Exhibition Centre (BITEC). The Trade Expo covered a range of different industries, including Rotomoulding, Water & Wastewater, Recycling & Recovery,

Umakant Savdekar, delivering Friday training seminar.

PU Tech, Green Tech, Adhesives & Coatings.

At the Rotomoulding Expo there were 20 exhibitors, 11 from China, 4 from India, 4 from Thailand and 1 from Italy. Trade Expos serve as dynamic platforms that foster growth, innovation, and collaboration for businesses of all sizes and industries. By bringing together professionals, customers, and stakeholders under one roof, these events can offer a wealth of opportunities to those who participate.

The rotomoulding Trade Expo and rotomoulding training seminars were held over 3 days – 12-14 March. Wednesday and Thursday were full training days delivered by Ian Hansen (RotoConsult – Australia) while Friday was a half day training session delivered by Umakant Savdekar (Phychem – India). This allowed Ricky and other seminar attendees time to visit the Trade Expo on Friday afternoon, the final day of the Expo. They had the

64 ROTOWORLD® ISSUE 1 • 2025

opportunity to listen to a supplier presentation on Hydrogen tanks from SCGC ICO Polymers in the Trade Expo.

At the training seminar, Ricky and his team were immersed in a world of potential and possibilities.

The different sessions covered

everything from how to use ASTM D1998 to calculate water tank wall thickness to optimising cycle times. Seasoned rotomoulding experts demonstrated how small tweaks in temperature control or powder quality could make a significant difference to achieving consistent quality outcomes. Ricky also participated in questions and answers during the training sessions, where he learned how to prevent common defects and experiment with innovative designs.

But part of the magic happened during the networking breaks.

Ricky connected with other rotomoulding professionals—some were seasoned veterans, while others were newcomers bursting with fresh ideas. They shared stories, challenges, and solutions.

One attendee introduced Ricky to a new and different polymer he hadn’t considered before, while another suggested a low cost temperature monitoring tool that simplified process monitoring

for his open flame rock and roll machine.

By the end of the seminar, Ricky felt energised and equipped. He was able to fly back to his factory with newfound confidence, eager to apply what he had learned.

Over the next few weeks, he implemented new techniques and saw immediate results: defect rates began to reduce, production efficiency improved, and his customers began noticing the quality of his products were more consistent.

As Ricky reflected on his journey, he realised that attending the training seminar had been a turning point—not just for his business, but for his mindset and that of his two team members.

It reminded him of the value of continuous learning and the power of community in solving challenges.

As you may have guessed, Ricky is not real. However, I have drawn inspiration from real-life occurrences and individuals to write this story.

In RotoWorld® Issue 4, 2024, there was an article focussing on Training & Skills development. In this I highlighted that employers have a responsibility to facilitate staff training and that this is an essential tool for competitiveness and the transformation of companies.

The March training seminar provided in Bangkok is another example of the opportunities which continue to be globally available for manufacturing personnel to attend in-person rotomoulding seminars. Most of the attendees at the Bangkok training seminars travelled from Southeast Asian countries around Thailand. They demonstrate the

commitment to training that some businesses are required to make.

Yet our industry continues to see many rotomoulders who cannot justify the time & cost to send their team members to training events organised more locally.

In February ARMO2025 was held in Delhi, India. Moulders could attend any 2 of 4 seminars held prior to the conference. Two of the popular technical seminars were ‘The seven stages of rotomoulding’ by Gareth McDowell

attendees more of a hands-on factory floor experience.

‘Tell me and I forget, teach me and I may remember, involve me and I learn’ attributed to Benjamin Franklin.

In May 2025 The Penn College® conducted their annual two-day intensive Rotational Molding & Hands-On Workshop, which includes the operation of an STP Rotomachinery LRM 1500 shuttle in Pennsylvania, USA. This training event is sponsored by M.Holland.

This training event is sponsored by Matrix Polymers, which helps offset some of the financial cost. This one day training course will include the operation of an electric Rising Sun CS 1000 shuttle machine to give

As written in RotoWorld® Issue 4, for businesses there are pros and cons in sending staff to rotomoulding training sessions — however it is ultimately the employers choice whether they’re going to enjoy more of the pros than the cons.

Knowledge comes from education. Without knowledge of the rotational moulding process, nothing is possible and with knowledge every impossible thing becomes a possibility, wherever in the world you are. R

BPF calls for companies to report fraudulent recycled material claims The British Plastics Federation (BPF)— the UK’s leading trade association representing the entire plastics supply chain, including plastic recyclers—is encouraging companies to report any fraud they encounter regarding false claims of recycled content in plastic products to the Environment Agency.

There is concern that some companies may be claiming that their products contain recycled content, when they do not, or that the amount of recycled content within products is being exaggerated. The motive for this could be to avoid the paying the Plastic Packaging Tax (PPT), or for non-packaging products,

68 ROTOWORLD® ISSUE 1 • 2025

ARMO NEWS

ARMA | ARM-CE | ARMSA | BPF | IT-RO | NORDIC ARM | StAR

to make. false claims to assist marketing efforts.

For many years, the trade association has argued that a verification and/or certification scheme is needed to reduce fraud. It feels systems have to be agreed at a national—and ultimately international—level to ensure a level playing field that does not disadvantage companies doing the right thing, while also ensuring the best outcome from the environment by maximising the use of recycled plastic, where possible.

Although the BPF hopes that companies will report fraudulent activity, it also feels more robust action should be taken against companies that commit fraud. Investment in UK recycling infrastructure is also required, it argues, as increasing domestic recycling will make material easier to trace and reduce the opportunity for criminal activity.

The BPF sent a letter to HMRC, highlighting its concern of potential fraud within the PPT in 2024.

It would be like the issue to have a higher profile amongst parliamentarians, so that solutions can be reached to minimise opportunities for fraud.

The trade association is aware of companies that claim to have been put out of business as a result of PPT-related fraud.

Examining this issue in detail, in 2022, the BPF and environmental charity RECOUP released a guide called Recycled Content Verification Systems, which is available to download for free online.

BPF Sustainability Manager Helen Jordan states: “Let’s remember that almost all companies have integrity and always try to act according to the law. However, a few bad actors can potentially tarnish the reputation of the entire industry and blight the image of recycled plastics in the eyes of the public. Companies that commit fraud also make it more difficult for legitimate companies to thrive. Recycled plastic is a low-carbon material, suitable for use in a huge number of products— not simply packaging. We’d like the government to encourage investment in improving the UK’s plastic recycling infrastructure while also taking steps to minimise opportunities for fraud. And we call on companies to report any instances of fraud they encounter to the Environment Agency so that appropriate measures can be taken against them.

The more fraud is reported, the more it will be on the minds of those in government.” R
