EDITOR’S LETTER

Q

uality is the ability of a product or service to meet customer needs, requirements, and expectations. It is not an inherent property, but rather it should be defined, applied, and controlled. What does it mean

to produce quality?

It means applying well defined methods and sharing a vision.

It means using quality operational tools, procedures, people, and skills.

It means working with a system that balances all these elements.

Quality is therefore the set of factors through which a company creates a product or service that meets effectiveness and efficiency requirements, i.e. customer requests, by optimising the resources used. Quality is a system and it should be pursued as such, through quality raw materials, staff training, and product certifications.

This issue of ipcm® includes a large section devoted to the aluminium treatment and finishing fields and it will be distributed at the Aluminium 2018 fair in Düsseldorf (Germany). The interviews included present a few common threads that we would like to share here.

First of all, what is the point in certifying a treatment phase and boasting that certification, if inadequate processes or materials are used at the previous or subsequent process stages? Speaking of aluminium, how much does the quality of metal or of the applied paint affects products’ compliance with certifications?

In order to offer truthful outdoor resistance guarantees, would it not be more useful to certify a whole treatment cycle rather than just one phase?

Secondly, simplifications should be avoided to produce quality. Speaking again of aluminium, the ban of chromium (VI) paved the way to numerous chrome-free alternative solutions that can be combined with a greater or lesser number of previous treatments. Some companies choose a pre-treatment process with acidic phases only, others opt for a combination of acidic and alkaline phases, and others prefer the oxidation flash technology. All these solutions are valid if considered individually, but the choice should be made based on the quality level of end products and not on criteria such as ease of management or investment size.

Thirdly, water treatment greatly affects process quality. Purifying and recycling water is not only an eco-friendly choice. If well conceived, it enables to keep the process parameters constant and well balanced. In other words, it creates quality.

You will find that all the topics outlined above are further developed in the next pages. This issue however also includes interesting and exclusive contents on the use of powder coatings, new colour collections available, low environmental impact innovations to pre-treat aluminium prior to coating and oxidation, recovery solutions for solvent-based paints, anti-friction coatings, and new resins to formulate better powders for the finishing of heat sensitive substrates.

Quality should be perfected with practice and be specifically aimed at a purpose: offering a higher quality than that required is a waste of resources; offering a lower quality certainly leads to disputes.

be made rationally by comparing numbers.

For example, acetonitrile is much more polar than acetone, but exhibits slightly less hydrogen bonding.

When studying the detailed characteristic properties of the solvent bond with resin, pigment metals and fillers, we can ascertain the use and breaking of such bonds into newer or similar products for use.

For example, toluene and benzene are more compatible with xylene than mineral spirits.

However, xylene is compatible with mineral spirits as well. Certain solvents are soluble with each other, some are soluble only to an extent and some are non-soluble. When reacted with resins and pigments, solvents change the loyalty towards their “house,”

Depending on the inventory, the products with common sheens, colors and densities are mixed together into batch sizes as an intermediate pulp. This is an important ingredient mix check stage, where pulp is created from the oil paint, resin, solvent, pigment or waste/scrap/lots. These pulps are usually made keeping in mind the usability for the final product. We again check the pulp batches on the final gloss and resin/solvent/ pigment/filler ratio on the basis of density, hardness, gloss, weight and viscosity.

SUSTAINABILITY

it scores less than a wax made locally in Sweden, as a result of the CO2 generated by its transport. Similarly, if a material contains a

high amount of solvent, its impact on the ozone layer will be higher than a solvent-free product.

Having first undertaken the complex process in 2015, AkzoNobel was the first global powder coatings supplier to obtain the declaration. The renewed EPD for its Interpon D range of architectural powder coatings (D1000, D2000 and D3000) lasts until 2023. The results show an improvement on the previous score and highlight various factors that are contributing to lower environmental impact, including a reduction in both waste and energy usage.

“In retail markets nowadays, it’s almost unthinkable that a product would not have its origin and ingredients printed on the packaging” said powders’ Architectural Segment Manager, Jean-Paul Moonen, “yet in industrial goods it is still a new concept to ask about the origin of the ingredients.

Environmental Product Declarations (EPD) are a first step on the way to change this.”

Among a plethora of green and eco-labels which are not independently controlled, EPDs stand out as a trusted benchmark. The factors to be included, and how to measure them, are controlled by an international ISO standard, and so are comparable from country to country, region to region and between different suppliers. Third-party verified EPDs are the gold standard, as they prevent manufacturers from making false claims. There are several recognition schemes, with LEED being among the leading ones. Using products with an EPD gives LEED credits, and more credits lead to higher LEED ratings (from Bronze to Platinum).

“EPDs are increasingly requested in the construction industry, as architects and building owners want their projects to be recognized as environmentally-friendly” continued Moonen.

“Powder is an inherently sustainable product, as it does not contain VOCs, but this is another step in offering our customers sustainable coatings solutions, so I’m very proud of this EPD certification for our Interpon D series.”

AkzoNobel supplies powder coatings to more than 30,000 customers worldwide, covering several market segments.

The company’s products are used on buildings and landmarks around the world, including La Sagrada Família (Barcelona, Spain); the Shard (London, UK); and the Water Cube (Beijing, China).

Touch the Colour With spectro2guide – Next Generation Colour Measurement

by BYK-Gardner © BYK-Gardner

B

YK-Gardner - worldwide partner of the automotive, paint and plastic industries for quality

control of colour, appearance and physical properties - is introducing the new spectro2guide, the revolution in colour measurement.

Like its predecessor, the new spectro2guide combines colour and gloss measurement in one instrument.

Completely new, is the measurement of fluorescence to predict colour stability.

Like a fluorimeter the fluorescent light can be detected using monochromatic illumination and for the first time ever an ΔEzero can be calculated to predict how the colour will change when fluorescence has degraded. This combination of a spectrophotometer with a fluorimeter opens up completely new perspectives to not only control colour harmony, but also to analyse the colour stability with measurement of fluorescence.

I prodotti Interpon di AkzoNobel sono amici dell’ambiente

Le finiture a polvere sono prodotti chimici vernicianti privi di solventi, di VOC (Composti Organici Volatili) e di metalli pesanti tossici, come cromo o piombo. Questi sono da considerarsi come requisiti standard per tutti i prodotti Interpon di AkzoNobel che sono formulati per rispettare l’ambiente e la salute dei loro utilizzatori.

Inoltre sono riciclabili, poiché l’over-spray può essere recuperato fino al 99%, e la maggior parte dei prodotti Interpon di AkzoNobel richiede un minor impiego energetico in fase di applicazione rispetto ad altri sistemi vernicianti.

The inlet sluice is sealed with easily replaceable and wearresistant rubber curtains in the upper part. They avoid the escape of abrasive and dust. The lower part is sealed by means of adjustable rubber lamellas which adapt to the contour of the respective work pieces.

While passing the blasting chamber itself, the work pieces are blasted evenly and accurately. Four AGTOS high performance turbines with up to 22 kW have been provided for this task. They are distinguished by their high performance and long life times of the wear parts. In case of maintenance, they can be changed relatively quickly and easily.

After having passed the blasting area, the work pieces reach the combined brush and blower unit. Here, the abrasive cleaned from the surfaces of the work pieces is returned to the abrasive circuit. In order to do this, the abrasive is collected in the hopper below the machine, forwarded by means of a screw conveyor and transported to the upper part of the machine by means of a bucket elevator.

There, bigger particles are filtered out and small grain and dust are removed from the abrasive. The purified abrasive is led from the abrasive silo back to the high performance turbines by means of the abrasive control unit.

The dust separation of the shot blast plant is realised by means of a cartridge filter. The filter has a fan which creates a negative pressure. A deflecting separator and filter cartridges with an appropriate medium clean the aspirated air. It is clean when it returns back into the factory hall. An additional filter provides double security.

Further topics at AGTOS exhibition booth AGTOS exhibition team will be happy to inform you about the different versions of the high performance turbines - the most important component of a shot blast machine - as well as their maintenance options. They reach a long service life also when using aggressive abrasive media. Examples of already produced machines will be shown and the best solutions for processing work pieces by means of shot blasting will be demonstrated.

Conclusion The decision to expand the company’s product and service portfolio with the Rotamat coater has proven to be a full success.

While initially only intended for the in-house production, Interseals very quickly received enquiries from other companies. That is how the Rotamat coaters were forming the foundation for a new, continuously growing business field.

The machines produce excellent surface finishes, are very sturdy and require a surprisingly low degree of maintenance. The first machine, delivered nearly 10 years ago, still runs at full capacity. A big help was

That is why in the beginning the experts from Haan intensively supported Interseals. But for several years now the colleagues in Italy and Poland have been adapting the coating process to new customer work pieces. But, of course, the experts from Haan still help Interseals with special questions and customer demands. It no doubt helps that the Walther Trowal technicians and engineers have been working with Interseals

work pieces.

The coating of mass-produced small parts in a Rotamat coater is a high temperature process, whereby the small parts are coated in a rotating, enclosed spray chamber. The process can be applied on parts made from different plastic materials like elastomers, ABS, PC, PS, etc., as well as parts made from metal and wood. The Rotamat systems allow processing of water based as well as solvent based coating materials.

The parts do no longer have to be placed individually on special racks but are simply loaded in bulk into the rotary drum of the Rotamat system. One or – even better - two automatic spray guns are evenly applying the coating material, while the small parts are gently tumbling over each other.

To induce the required process temperature into the parts, warm air is injected into the coating drum with an absolute minimum of turbulence.

The work piece temperature is directly measured with an IR sensor. Depending on the work piece temperature a PID controller regulates the temperature of the inlet air always taking into account the actual air volume. Due to its outstanding efficiency the Rotamat coaters require only a few kW’s of installed electrical power.

Once the coating process is completed, the work pieces are discharged by simply tilting the drum downwards with a gear motor. A post process drying step, for example, in an oven, is no longer required. The parts coming from the drum can be immediately used for the next production step.

Its quality-oriented approach did not change even following the serious financial crisis that hit Cyprus in 2013, causing numerous companies to collapse. This firm’s entrepreneurial ability, passion for aluminium, and great technical expertise have enabled it to go back to producing, although below its capacity, exporting all over the world, and investing in technology.

The company has also invested in production and it will soon add a fourth 20,000-ampere oxide tank to the three 16,000-ampere ones already present on the anodic oxidation line, bringing the total capacity of the plant to 68,000 amperes (Fig. 1).

economiser that recovers the extrusion

Muskita, a Cyprus-based manufacturer of aluminium profiles and accessories, has a history of success. The history of a firm that has turned its technology investments into a weapon to conquer the global market starting from a little corner of Europe. The history of an obsession with the quality of raw materials and processes, which made it one of the few, if not the only company that has never had any complaint about the durability of its finishes or the filiform corrosion of its profiles in the last fifteen years, i.e. since it adopted a chrome-free pre-treatment process.”

had any filiform corrosion problem even in the harshest environments. There are two reasons for this success: the exclusive use of primary aluminium for extrusion and the collaboration with highly skilled partners, with which there is a continuous exchange of knowledge and experience.”

In 2013, Muskita suffered the Cypriot financial crisis: due to the failure of national banks, the economy was at a standstill and a turnover reduced by 60%. “That period tested all of us and shook Muskita from the ground up. However, today we are back to working well, although far below our potential and with slower exports. On the other hand, these moments of slow production are often the most creative ones: we have diversified our range and we have developed new products and services.

And here we are, once again at the forefront of the global aluminium market”.

Muskita has invested in an accessory phase of the coating process, greatly affecting productivity, energy efficiency, and operational safety: it has installed a paint stripping system to treat its profile hanging hooks, choosing the technological evolution of the Fastrip ISP machine produced by Alit Technologies (San Bonifacio, Verona, Italy). The system will help increase the speed of its coating line and it will enable the company to significantly reduce energy consumption and process costs. This is crucial for a company like Muskita, bearing much higher costs for energy supply than in the rest of Europe.”

“The choice of primary aluminium for extrusion largely affects our products’ performance. However, quality can only be achieved through a production process that is quality-oriented in all its phases,” says plant manager Andreas Marcou. “It makes no sense to certify the pre-treatment phase, if the substrate is of poor quality or if non-compliant raw materials are used in other process steps.

Quality is a system, and it should be treated as such. We only use primary aluminium for extrusion because we do not want to contaminate our warehouse with extruded parts that are not of high quality, but also because its advantages in terms of higher

“Our collaboration with Muskita started about ten years ago, when they decided to implement a chrome-free pre-treatment process,” says Loris Rossi, representing Alufinish. “We currently supply 75% of their anodising products.

customers, the planning department determines the profiles to be picked up and sent to the oxidation (Fig. 7) or coating station. Once assembled through thermal cutting, the end products are sent to our four warehouses located in the main cities of the Country: Pafos, Larnaca, Limassol, but we can oxidise or paint parts up to 7.2 metres in length upon request. We can also supply raw profiles up to 9 metres.” Muskita’s coating station is a vertical plant provided

The Fastrip ISP system installed at Muskita’s premises is a 6-metre long chemical stripping tank, with a capacity of 2 tonnes of product and with a hook immersion depth of 30 cm.

It is the first tank of this type to have a wall heating system with diathermic oil. The stainless steel tank is jacketed and it contains a circuit fed with electrically heated diathermic oil, which guarantees very low operating costs and optimal temperature maintenance.” because, although spraying ensures more uniformity on the outside of the workpieces, the cascade process allows to pre-treat also the inside of profiles,” explains Marcou.

“For us, guaranteeing a Seaside quality level means to use first-choice metal, correct pre-treatment processes, and Qualicoat Class 2 coatings. That is the secret for not receiving any complaints for corroded or chalking profiles.

Also the choice to use only Class 2 paints stems from our quality policy: we do so also for our wood-effect finishes obtained by sublimation, where we use films of the same quality.”

For Muskita, colour is crucial, too. “Our main supplier, accounting for about 70%, is Sherwin Williams with the brand Syntha Pulvin. We also use colours from Akzo Nobel’s Futura and Structura ranges. Together with GI Color, finally, we have developed a 12-tint collection called “Colours of Earth” as well as all wood-effect finishes obtained by sublimation. In total, we manage about 100 colours, plus the ones that we have formulated by our partners on request,” says Andreas Marcou.

Fastrip ISP: paint stripping contributes to quality Using hooks that are perfectly suited to each coating process is fundamental in a quality system: it is the only way to ensure perfect electrostatic conductivity.

That is why properly paint stripping all hooks between one cycle and another is crucial, too (Fig. 9). “Before installing Alit’s machine, we used an induction system that did not guarantee perfect cleaning results and above all modified our hooks’ metal structure, thus

“The transition from Cube to the new line was perfect and smooth, since the technology is practically the same, except for the FOX system,” states Burke. “The plant is very easy to use: the control PLC works like a Windows system: it is possible to “browse” through the various process phases.

SAT’s engineers are highly skilled and they deeply know their technologies. Their support was essential to adapt to the use of such a large treatment line. Even the installation phase was smooth: it took three days to start and test the electrical and mechanical parts, and the system had been already started while we were still in Newport.”

Two pre-treatment technologies in one line The peculiarity of AluK GB’s new coating line is the integration of two different pre-treatment systems: a conventional chemical cycle, with a double active stage (acid and alkaline) and a chrome-free conversion

based on the quality requirements of the aluminium profiles to be treated, we can decide whether to divert the parts toward the oxidation tank for a flash treatment aimed at improving their corrosion resistance or to complete the conventional cycle (Fig. 8).”

The latest version of the FOX system was implemented. “Originally, the FOX system was based on two separate tanks, one for the flash oxidation process and one for rinsing the profiles. The speed of the main conveyor was limited by the number of profiles that could be processed by the tanks, thus limiting productivity accordingly,” says SAT sales engineer Alberto Formenti. “In the latest version of this system, however, the oxidation tank is wider in order to immerse several profiles at the same time (Fig. 9), whereas the rinse with demineralised water occurs vertically in a spray tunnel module.

In this way, the main conveyor of the coating line can transfer a greater number of profiles

56

AluK GB has always considered the finishing of its products a commercial lever: since 1992, when the company opened up, they have focused on the finishing process by entrusting it to expert contractors. However, a leap in quality would have been possible only by insourcing this operation. That is why they needed adequate technical and training support and SAT turned out to be a partner with which they could grow and above all a plant engineering firm able to provide the ideal product to achieve market objectives from time to time.”

N. 53 - SEPTEMBER/OCTOBER 2018 - international PAINT&COATING magazine

“Otherwise, the profiles proceed on their path toward the chrome-free passivation station. The winning aspect of this plant is its flexibility in terms of final quality.

The company can offer a standard and more affordable product using the chrome-free pre-treatment as well as a premium quality, more expensive product using the flash oxidation technology, thus meeting the requirements of the most diverse aluminium markets.”

“The anodising process lasts 3.51 minutes.

We recover part of the sulphuric acid in the solution from the dripping of the profiles and we recirculate it into the system,” states Michael Burke. “Moreover, we converted the rinse with mains water included in the original project into a rinse with demineralised water, thus obtaining great benefits: the anodising process is always critical and strict parameter control is required.”

“In terms of application, dense phase is the first choice for coating aluminium profiles, although it requires a greater investment than the Venturi injector technology,” states Leon Hoog, the UK Business Unit Manager of GEMA. “However, it is the best technology available today as for transfer efficiency, extrusion penetration, paint yield, and standard thickness deviation (Fig. 12).”

The two coating booths work simultaneously: during loading, the software matches each bar with a treatment program and with its assigned booth’s number (Fig. 13).

“One of the greatest benefits of the plant technology supplied by SAT is that no empty spaces are needed on the chain: this has considerably increased our production

SAT’s technology comes into play after the rinses following the acid degreasing stage: here, based on the quality requirements of the aluminium profiles to be treated, they can decide whether to divert the parts toward the oxidation tank for a flash treatment aimed at improving their corrosion resistance or to complete the conventional cycle.”

FOCUS ON TECHNOLOGY

The winning aspect of this plant is its flexibility in terms of final quality. The company can offer a standard and more affordable product using the chromefree pre-treatment as well as a premium quality, more expensive product using the flash oxidation technology, thus meeting the requirements of the most diverse aluminium markets.”

Thanks to its in-depth knowledge of the mechanical and optical characteristics of aluminium and of surface treatment processes, as well as to constant investments in plants and equipment, ALMECO currently has a production capacity of over 20 thousand tonnes of aluminium and more than 3 million reflectors per year. Lighting has always been its core business, from the production of high reflectance anodised aluminium to the design and construction of reflecting optics and reflectors.”

ALMECO’s production organisation consists of four different units, each structured to manage the specialised process of aluminium manufacturing, depending on the treatment to which it is subjected and the application sector for which it is intended. The Italian plant in San Giuliano Milanese is the Group’s headquarters: in addition to the production of anodised aluminium for the lighting and decorative industry, it focuses on the design and production of reflectors for lighting fixtures.

In order to meet the use requirements of aluminium in the decorative field, the Group has developed Bandoxaldecor™ (ref.

Similar to an extrusion anodising process, the cycle includes brightening, anodising, colouring, and fixing phases.

Brightening is the electrochemical process in which aluminium strips are immersed in a tank containing a concentrated mixture of high temperature acids and they are subjected to the action of electric current to smooth their surface in a controlled way and improve their gloss and reflection properties.

CIE has developed this water treatment process for a continuous flow anodic oxidation line by implementing a technology that exploits special multi-exchange resins to recycle rinsing water and a chemical-physical purification phase for concentrates that uses the PUR-ALL® ZERO ZERO technology. This guarantees total elimination of pollutants and minimisation of the resulting liquid, which is sent to a special evaporator with half the energy consumption.”

A unique water treatment plant in the world “We have developed this water treatment process for a continuous flow anodic oxidation line by implementing a technology that exploits special multi-exchange resins to recycle rinsing water (Fig. 6) and a chemical-physical purification phase for concentrates that uses the PUR-ALL® ZERO ZERO technology. This guarantees total elimination of pollutants and minimisation of the resulting liquid, which is sent to a special evaporator (Fig. 7) with half the energy consumption,” says Franco Falcone from CIE. “The plant allows to renew the rinsing liquids with a very high flow rate, ensuring maximum water quality and a conductivity value of less than 100 microsiemens. The water leaving the chemical-physical unit is conveyed into an evaporator: the distillate generated by evaporation is recovered and used as rinsing liquid, whereas the residue (less than 2%), exclusively made of neutral sodium salts, is disposed of by an external company.”

“This is an innovative system because it is the first example of total zero liquid discharge on an anodic oxidation line. CIE already had plenty of experience in the installation of plants ensuring a 50% water recovery rate (e.g. the one installed by TALEX in Abu Dhabi1) and featuring our PUR-ALL® 1

technology (based on a chemical system exclusively owned by our subsidiary MST Chemicals). In ALMECO’s plant, PUR-ALL® was used, but it is not the only technology implemented: it only deals with the purification of acid water. For alkaline water, we have added a complementary technology whose effectiveness is such as to guarantee total recycling of all process waters, thus eliminating any form of discharge or disposal,” explains Falcone.

“The plant we have installed for ALMECO is exceptional: we recycle 100% of rinsing water, an outstanding result considering that the quality of coils and therefore of the treatment water must be very high. It is very difficult to deposit anodic oxide and brighten aluminium coils with such a high aesthetic homogeneity, and ALMECO’s qualitative requirements for rinses were very strict. With our technology, we have allowed the company to achieve excellent treatment results without the need for any environmental authorization in terms of water. We are now finishing the commissioning phase and the company has already expressed satisfaction with its choice.”

“Since the tanks of a continuous anodic oxidation line are very large, about 25-30 m3, ALMECO should have discharged at least 20 m3/h of liquid: with our plant, they do not discharge anything,” states Franco Falcone. “The main advantages are a reduction of at least 18-19 m3/h in water

With MEDSEAL® 08 the pore widening is very fast: after only 5 minutes the pore size has increased from 12 to 14 nm. On the other hand, in the absence of MEDSEAL® 08, pore widening is extremely slow, especially at the beginning. It takes 45 minutes to increase the pore size to 14 nm. If we compare the necessary time to get from 12 to 14 nm, it takes only five minutes with MEDSEAL® 08 and 45 minutes without MEDSEAL® 08. Therefore, by adding the catalyst we speed the process up about ten times in the initial stage. However, if we consider the complete process, the catalyzed sealing is only 3-4 times faster overall. Hence, the catalyst plays a very important role in the initial dissolution of the alumina.

line to the new sealing process. In response to this problem, Alsan has developed FRIOFIX® ECOLINE, a new nickel-free cold sealing process.

Since last June, FRIOFIX® ECOLINE (QND-011) is the first and only free of nickel cold-sealing product approved by the quality label QUALANOD. This process ensures very similar working conditions to those used with the

28 % lower than working at 85 ºC and 3 minutes per micron.

According to the literature, the mechanism of hot sealing is mainly divided into two different stages: in the first one, the pore walls dissolve and that explains pore widening, while in the second stage the aluminium from alumina dissolution precipitates as hydrated alumina.

The volume of hydrated alumina is higher than the volume of anhydrous alumina and pores get blocked.

In order to find out how MEDSEAL® 08 accelerates the sealing process, Alsan studied the morphology of the anodic layer at different times during the sealing process by Scanning

At the Clark’s abrasion test, thickness losses from anodic coating were on average lower with FRIOFIX® ECOLINE, probably because the hydration sealing at higher temperatures has a little negative effect on the abrasion resistance of the anodic coating.

Regarding the admittance test, and opposite to what happens with the sealing by impregnation with nickel salts, the conductivity of the anodic layers sealed with FRIOFIX® ECOLINE is extremely low, and clearly below the values measured in the reference hot sealing.

Finally, at the accelerated corrosion test, the presence of corrosion pits after 1000 hours of exposure was not observed in any case, only iridescences and small spots of similar size and extension appeared in both types of sealing (Fig. 9).

its employees have over twenty years of experience and know-how,” explains Alfredo Calvano, the Technical and Plant Manager of Luxe Coat (Fig. 1). “Luxe Perfil’s interest has enabled the reactivation of two coil coating lines and to approach an ever-booming market thanks to targeted investments. This has allowed Luxe Coat to become one of the major players in the aluminium coil coating sector (ref. Opening photo) in relatively little time.”

The first step for this business relaunch was the revamping of the coating systems, with the aim of making them as flexible as possible and increasing their production capacity. Two painting systems in L’Aquila (Abruzzo) have been acquired. Both lines had been stopped during the financial crisis and a turnover of different companies. Through a targeted intervention, not only have they been put back into operation, but also modernised and modified to meet the commercial and production goals set by Luxe Perfil,” says

In continuous coating processes, e.g. coil coating operations, it is crucial to keep quality constant and ensure that the plant is versatile enough to meet the market’s needs without sacrificing high productivity, crucial to competitiveness.

Luxe Coat Srl (Bazzano, L’Aquila, Italy) specialises in the continuous coating of aluminium alloys.

The company was founded

by Luxe Perfil, a Valencian company operating in the aluminium market, which found in Italy, and especially in L’Aquila, the ideal solution to increase production capacity and expand into the European market.”

The pre-treatment stage employs chromefree acids and it is the same on both plants.

“The chrome-free products used are Qualicoat approved. In the first phases of the process, the product is applied by spray and the interlocking tanks have a capacity of 10 m3,” explains DN Chemicals Sales Manager André Bernasconi. “The decision to adopt an acid product instead of an alkaline one was based on the technical experience of Luxe Coat, which found acid products ensured greater cleaning efficiency and better paint adhesion.”

Thanks to the arrangement of the system, which includes 7 tanks devoted to pre-treatment, Luxe Coat and DN Chemicals were able to experiment and test different types of products without slowing down the coating process (Fig. 4). “Over the year, we have conducted a series of industrial tests to analyse and select the best products and © ipcm ®

FOCUS ON TECHNOLOGY

From the start in 2000, excellent coating results were achieved with this process. At the same time, Alufinish had the opportunity to gather valuable experience in dealing with the still new chromium-free technology.

Based on their successful achievements with Alficoat 748/3, it was hardly surprising that ELVIAL again relied on this technology when building their new production location in 2005 (Fig. 1).

The facilities that have since been built on the almost 40-acre site owned by the company include modern, vertical pre-treatment plant with surge technology in addition to robot-controlled transportation engineering and a large profile warehouse.

The vertical line is made completely of 316 stainless steel. It is designed in tunnel form, has 12 process stages (Fig. 2) and is

robotic systems, the company is today able to fulfil even the most individual wishes of their customers. Besides extrusion lines, ELVIAL currently operate two coating lines (one horizontal and one vertical unit), both Qualicoat-Seaside class certified.

The first chromium-free application using Alufinish products was implemented in a horizontal spray unit at the former production site in Kilkis. The Alufinish products used at the time were a simple combination of alkaline pickling and degreasing solution (Alfinal 273 – Alfisid 12), acidic pickling bath (Alfideox 74), and chromium-free pretreatment (Alficoat 748/3) (Table 1). This plant is still in operation.

The pretreated goods leave the long tunnel after the chromium-free pretreatment and are then dried in the retained water drier.

This vertical installation is designed to allow maximum flexibility and currently has three acidic process stages. Cleaning and pickling are carried out simultaneously in zone 1 using Alfideox 74 and Alfisid 14. In zone 4, the same Alfideox product is used again for acidic post-pickling. The two-component product consists of Alfideox 74 – a pickling component with fluoride content – and the cleaning intensifier Alfisid 14. This method is particularly interesting whenever it is necessary to remove thicker oxide layers. Instead of having to implement the requirement in a single zone,

After 13 years of operation, the chromium-free ENVIROX NR process (Alficoat 748/3) is fully established in the vertical line at ELVIAL and provides the consistently high level of surface quality demanded by customers.

Alficoat 748/3 generates colourless corrosion protection layers with titanium content which can be established, both on a quantitative as well as a qualitative level, by means of photometric layer determination and rapid test (staining). At ELVIAL, the product functions in a concentration range of just 4 – 6 g/l and is consequently very economical. Besides this, the continuous partial replacement of the bath solution also warrants consistent processing conditions and a guaranteed pre-treatment quality.

that has been successfully tested by major manufacturers of extruded aluminium profiles is a pre-treatment phase with a mechanical shot blasting process performed in an automatic turbine system, followed by a quick immersion in an alkaline bath to complete the finishing treatment. Shot blasting quickly eliminates most of the surface defects generated by extrusion and handling operations, while creating a pleasant, uniform satin effect (ref. Opening photo). The subsequent pickling phase, therefore, has a mere finishing function, thus being much more delicate.

Some product characteristics, however, make it difficult to get optimal results. First of all, profiles have complex shapes and, therefore, they require careful positioning of the

In other words, if a chemical-only treatment takes 20 minutes, the finishing pickling process after shot blasting may last only 4 minutes. This evidently ensures three benefits: - limited size of the plant and production area; - reduced total processing time; - reduced dispersion related to the material corrosion.

This increases productivity and overall efficiency. In particular, it is possible to obtain

POLIFLUID® has allowed us to solve all our application issues without having to change the whole application system of our coating plant: with a small investment, we have been able to continue to use the equipment already present on our line without replacing it.”

“Eurosider technicians have worked in close cooperation with the Italian customer: we were very willing to find the best solutions for them and solve any problem found” Ottavio Milli (Fig. 6), CEO of Eurosider in Grosseto, Italy, explains. “During the first month, we would

New High-Performance Turbines for Aluminum Components he increasing processing of aluminum

requires new developments in surface technology. What is needed are economical concepts for deburring, cleaning and finishing the aluminum workpieces.

Aluminum workpieces are increasingly being processed with aluminum abrasive. For this application, AGTOS engineers and technicians have developed new highperformance turbines (Fig. 1). One turbine can be seen as an exhibit at the AGTOS booth of the ALUMINUM fair in hall 12, booth 12I20.

In addition to the blasting processing, the gentle handling of the workpieces is important.

Only if both is matched to the aluminum workpieces the quality of the surfaces can meet the

our production more versatile, we have

The success of this company is due to several factors, including its ability to present itself as a specialised aluminium extrusion centre. Its production cycle starts with the purchase of raw material and it continues with melting, extrusion, coating, and distribution operations – a process involving seven production plants and thirteen distribution centres located in Italy and abroad (ref. Opening photo).

Besides presenting itself as a singlesource supplier, over the years All.co has been able to cope with market fluctuations by adapting its production to the current demand and thus ensuring constant growth and affirming itself on the international markets. “All.co designs and manufactures aluminium extrusions for the industrial and construction sectors, handling all phases in-house,” says Luigi Vecoli, the coating manager of the All.co Group. “In 1991, we even insourced the coating process to offer an extra service to our customers. We mainly paint material for the construction sector. This has enabled us to meet the needs of the market in terms of finishing, which, especially in recent years, has

on foreign markets, which have become our main target, as the Italian aluminium market is still slow,” states Vecoli.

All.co has been actively collaborating for more than ten years with Inver, a manufacturer of industrial coatings belonging to the Sherwin-Williams Group, as well as the main supplier of the Syntha Pulvin® branded polyester powders used

by All.co. For even greater production flexibility, also the vertical coating plant designed by Trasmetal (Milan, Italy) underwent a revamping in the 2014, with the installation of a new coating booth equipped with two OFB disks, able to treat profiles up to 6 metres and with an overall capacity of 40 tonnes per day.

Combining production versatility and quality consistency “Our collaboration with Inver began in 2004. The first few years have been a trial stage for both parties: since we previously had other suppliers, Inver had to analyse our colours and adapt its products to our needs,” explains Luigi Vecoli. “Much of the material painted in our Pisa plant is sent to © All.co

“Our production system is completely computerised.

“The profiles then reach the polymerisation oven (Fig. 9), operating at a temperature of 180-190°C. A storage buffer allows for effective cooling before unloading (Figs. 10 and 11).

This much longer unloading station allows us to manage orders according to our current needs, postponing or anticipating operations without ever stopping production or slowing down the weighing and packaging procedures, which are performed automatically to minimise the possibility of damaging the material.”

During production, we take samples of each colour at the beginning, in the middle, and at the end of the coating cycle.

We then perform the tests required by the certification – scratch, impact, tear-off, and bending tests – as well as a salt spray test to ensure a 1000-hour resistance value.”

“Before working with Inver, we already had our own tints, which Inver has managed to reproduce and adapt to its products,” says Vecoli. “This may seem a secondary factor, but finding the right colour is never easy and quality can be affected if the formulation is not correct. For instance, door and window profiles are often coupled and even a minimal

“The Italian market still prefers Class 1 powders. However, as increasing attention is paid to quality, the request for Qualicoat Class 2 certified products is raising,” states Marco Canola.

“In future, we plan to further strengthen our collaboration with All. co and offer to the Italian market an added value for conventional products, that is, better performing powders (as proved by our accelerated tests), already widespread in Germany and England.”

SUSTAINABILITY The revolutionary process of coating by powder The powder production process involves mixing, extrusion, milling and sieving steps, after which the powder is typically applied electrostatically, followed by curing under heat to allow it to flow and ultimately harden. The powder coating formulation consists of a binder (resin and crosslinker), pigments and additives.

Powder coatings are mainly used for the coating of metals, such as household appliances, aluminium extrusions and automobile and bicycle parts due to the high temperature that is required

significant efforts towards reducing the curing temperature: this has been the driving force to further reducing the required energy of an already ecological, low-footprint process. This creates an increased demand for low-temperature curing powder coatings without adverse effect on the curing times, which are also important for lowering manufacturing costs.

DSM has been a pioneer in developing polyester resins since the 1960s, and, through its ongoing commitment to resin quality, consistency and sustainable growth, has become the world’s leading

“These standards are exceptionally high for indoor steel structures.

All outside structures had to be galvanized steel”, explains Mika Jäsperlä, Design Manager of Ruukki Construction.

“In protective coatings, we must consider not only the final purpose of use, but also logistics. An element made for indoors has to withstand varying weather conditions during transport, such as overseas shipping. Our epoxy primer gives steel structures excellent chemical and abrasion resistance and our polyurethane topcoat protects them from the weather and ultraviolet radiation. This ensures, that the final structures fully match the architects’ vision”, says Mikko Soini, International 1
