The Magic of Dry Ice in Plastic & Rubber Molding

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 and dry ice aligns well. The feedstock for dry ice comes from recycled CO2 as part of a carbon capture & utilization process from numerous industrial by-products. Plastics 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.
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 and in an 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.
