Want to utilize more efficient and environmentally sustainable cleaning methods? Want to lower your Greenhouse Gas (GHG) emissions score? Start using dry ice.
It's no secret that sustainability and ESG initiatives are rising to the top of the corporate priority list. Plastic processors are aligning their corporate goals to remain responsible, competitive and resilient. Utilizing dry ice in several applications in plastics processing is helping the industry move into a circular economy to better protect our environment. How? The CO2 utilized for the production of dry ice is a Carbon Capture and Utilization process that involves using recycled CO2, and replaces environmentally harmful solvent cleaning processes.
Plastics and Rubber processors are under great pressure to increase the productivity of their equipment, improve the quality of their parts and reduce costs. This can be a balancing act between using the most effective technologies and working within a tight budget.
Mold cleaning remains a critical component of producing quality products. Cleaning mold cavities and vents of resin off-gasses, cured material or mold release agents can prevent numerous common molding problems such as short shots, burns, flash, contamination, etc. Cleaning is often delayed because traditional methods cause extended downtime and often involve the use of chemicals or mechanical means that are harmful to employees, abrasive to the tooling and can wear away critical mold tolerances.
We understand this problem and offer solutions to clean molds more often, faster, cheaper and non-abrasively, in a sustainable, environmentally sustainable manner. Cold Jet’s Dry Ice Environmental Cleaning and Surface Preparation (ECaSP) systems present a proven solution to accomplish productivity, quality and cost reduction initiatives that many plants are pursuing.
Dry ice is also utilized in our industry to deburr and deflash plastic parts. Thermoset parts will always have flash (sometimes thermoplastic parts as well), and the part geometries do not always lend themselves to tumbling. Our solutions are often completely automated.
Lastly, we offer solutions with on-demand dry ice production and blasting for the surface preparation/cleaning of plastic parts prior to painting. Cold Jet systems are designed for easy integration into existing automated paint line systems. They replace aqueous cleaning methods and the associated problems that come with wet cleaning: large floor space needed for drying oven, high operation costs for a drying oven and water reclamation system and scrap parts that do not dry thoroughly.
Thank you for your interest in our technologies and solutions. As you explore this magazine, you will discover the numerous problems that dry ice is solving in our industry. We look forward to working with you on your next dry ice cleaning project. Should you have any questions, or if we can be of assistance in any way, please do not hesitate to contact us.
Due to the fact that dry ice is recycled CO2, it will not contribute to your greenhouse gas score. In the calculation of a carbon footprint, CO2 is accounted for at the producer level. It is not counted a second time at the point of use.
GIVING
Dry ice is based on the conversion of captured carbon dioxide (CO2) into a value added, commercially useful product. It's the product of the carbon capture and utilization (CCU) process in which CO2 is captured at industrial, biogas, or ambient air capture facilities, converted to liquid CO2, and transformed into dry ice - giving it a second life as a cooling and cleaning medium.
California Air Resources BoardDry ice is non-abrasive, non-conductive and will not damage surfaces or equipment. By sublimating on impact, no secondary waste is left behind. It is also non-toxic and safer for employees than traditional cleaning methods. These attributes make dry ice cleaning an efficient, cost effective, environmentally sustainable, and occupationally safe cleaning solution.

Impact of pellets creates a kinetic energy effect. The soft dry ice is accelerated by compressed air through specially designed nozzles at supersonic speeds.
Cold temperature of dry ice pellets creates a thermal effect. The temperature of dry ice (-109F/78.5C) causes the contaminant to embrittle. This helps break the bond between the substrate and the contaminant.
Expansion of the dry ice pellets. Dry ice pellets sublimate upon impact, volumetrically expanding in size by 800%, removing the contaminant.
Dry ice cleaning is similar to sand, bead and soda blasting in that it prepares and cleans surfaces using a media accelerated in a pressurized air stream. It differs in that dry ice cleaning uses solid CO2 pellets or MicroParticles, which are blasted at supersonic speeds and sublimate on impact, lifting dirt and contaminants off the underlying substrate.
Because dry ice is non-abrasive and turns to gas, you are left only with a clean surface that extends the asset life of your mold.
Dry ice blasting definitely results in a superior clean, and with less downtime, we have been able to increase production. Our automotive customers have very stringent quality control procedures and demands, and dry ice blasting has helped us meet those requirements.
Vice President | HuskyDry ice environmental cleaning and surface preparation systems allow for cleaning tools on-line and at operating temperatures, thus increasing machine uptime, mold asset life and profitability.

Maintaining clean mold cavities and vents is a major concern for plastic part manufacturers in meeting today’s high quality standards. The build-up of unwanted surface residue from either the product mix itself, mold releases or the labeling process can create various problems, ranging from product release (“knock out”) to inferior product quality and possible tool damage. Flash on the product also creates challenges for manufacturers. Mold halves can leave a parting line in the final product, and that parting line, or flash, must be removed to preserve product quality.
Traditional cleaning and deflashing methods involve tedious and ineffective manual processes using chemicals and hand tools. Cold Jet’s alternative cleaning process provides a non-abrasive and environmentally sustainable method that allows molds and products to be cleaned in a fraction of the time, allowing increased cycles between preventive maintenance. In addition, molds can be cleaned hot and in-place, without water, chemicals or the creation of secondary waste.

Cold Jet’s ECaSP systems have helped molders reduce annual costs and meet stringent industry demands: 6-Sigma, Kaizen, 5S, TPM (Total Productive Maintenance). Our systems enable molders to optimize their manufacturing process by cleaning contaminants from cavities, vents and hard-to-reach places faster, better and more economically than traditional methods. This can reduce cleaning times by as much as 75% and decrease annual mold cleaning costs by as much as $50,000.
Molders are very familiar with the requirements of precision (high-tolerance) and micro-molding parts and the difficulties that come with them. Keeping small orifices, micro-cavity production molds - as well as the deep, complex geometry of micro tools - clean is a critical concern when manufacturing high-tolerance plastic parts. Dirty molds cause vents to fill up and cause a variety of molding problems: burns, short shots, foreign particles, flash and plate-out. After the vents fill, a sticky and sometimes abrasive off-gas is forced between other close-fitting tooling. Mold damage can also occur from trapped air “dieseling” or “jetting” due to clogged vents.
Example calculated based on: Maximum production, pre-set mold cycle time, estimated profit per preform, etc. Not taken in consideration: Savings by labor cost, reduced repair costs, extended equipment lifetime.
Cold Jet systems have helped packaging molders meet stringent productivity demands. Our systems help molders clean faster, better and more economically, increasing production capacity and improving product quality. Mold cleaning times can be reduced by up to 75% with Cold Jet.
Dry ice cleaning technology allows molds, lock rings, cores and gate inserts to be cleaned without the disassembly of the stripper plate and while the mold is still in the press. The system also cleans blow molding machines, palletizing equipment, conveyor belts, airveyors and glue machines.
In addition to the molds, conveyor and PET dryer, we have also eliminated nearly three days of downtime by using Cold Jet's system to clean the injection screws on our presses, a process that usually required us to send the screws offsite.

* Take that 80% cost savings over 10-30% of the overall part costs
In the arena of flexible packaging - such as blown film lines - cleaning the dies, sizing ring and collapsing tower is critical in order to maintain output and quality. Oftentimes, an additive or slip agent is compounded into the resin to increase the output of the extruder. This additive will off-gas, leaving a waxy substance on the tower. Dry ice cleaning is a non-abrasive method that can quickly remove the contaminant while minimizing line downtime.
The cooling rolls in the sheet extrusion business are one of the most important aspects of the line. Cleaning with dry ice helps take care of your rolls so that they can work effectively. MicroParticles are a good solution for cleaning cooling rolls whether they are embossed or not.
It has drastically improved our productivity and helped us cut costs. Simply put, dry ice cleaning is the best cleaning solution for our needs.

Because silicones flash very easily, molds for these high performance thermoset elastomers are manufactured to critical tolerances, often +/.0002 inches. Protecting the critical dimensions on parting lines and sealing surfaces, as well as the mold surface finish, is vital. It is also important to keep the vents open in order to evacuate the air out of the mold prior to injection – this helps to produce high quality molded parts.
With Cold Jet dry ice cleaning, you can clean molds in the machine at processing temperature (typically 250-400 degrees Fahrenheit), without causing mold wear – thus increasing production capacity and improving product quality.
Cold Jet systems have helped medical industry manufacturers meet stringent industry process demands for quality and consistency. Our systems enable manufacturers to optimize their process by cleaning contaminants from cavities, vents and hard-to-reach places. This is done without the use of chemicals, which eliminates the cross-contamination concerns from chemical residue on the mold and ensures that products are delivered without flaws.
Dry ice blasting helps EV battery manufacturers reduce scrap and downtime, improve product quality, and prolong the life of their equipment.
The process is used widely in battery production to clean the agitators on mixers, allowing manufacturers to reclaim and reuse their mixed ingredients. It is also heavily used to surface prep parts prior to bonding, remove adhesives, clean battery cells after electrolyte filling, and deflash parts so they don’t puncture battery separator walls.
Additive manufacturing technologies are advancing at a record rate, but post-print processes can still rely heavily on manual skilled labor which is time consuming, increases part cost, and reduces efficiency and throughput.
Dry ice cleaning is gentle enough not to abrade the surface or ruin the part, yet aggressive enough to remove support structures, surface imperfections, and parts from powder cake.
Dry ice cleaning is a non-abrasive and environmentally sustainable alternative to traditional cleaning methods that does not produce secondary waste. It is a faster, more effective process than aggressive sanding or using hand picks to clean parts, providing an opportunity for additive manufacturers to grow at scale.
