CO2 Cleaning Effectively Generates Contamination-Free Mold Surfaces

Cool Clean Technologies is highlighting its specialization in CO₂ cleaning. The company’s spray-based products incorporate CO₂ in all phases for cleaning, surface preparation and plastics deburring, removing contamination from a wide range of surfaces. Its CO₂ spray methods can be configured in two ways: dry ice blasting and CO₂ snow cleaning.

Dry ice blasting is a fast and effective cleaning solution that surpasses traditional methods for plastic and rubber molds. Dry ice blasting is an aggressive form of cleaning using dry ice pellets, referred to as “blasting rice.” When pellets of dry ice are propelled at high speeds and impact the mold, they sublimate immediately, transferring kinetic energy to the surface and removing any existing debris.

Alternately, CO₂ snow cleaning generates the cleaning spray by condensing liquid CO₂ to solid CO₂, or “snow,” inside the spray nozzle assembly. CO₂ spray cleaning systems provide cost-effective, no-touch cleaning that can be dropped into existing production lines with a fraction of the footprint of water-based cleaning. Further, CO₂ cleaning is easily automated for surface preparation on automotive plastics.

Importantly, Cool Clean Technologies says there is no waste disposal required when using these solutions, as there are no byproducts, spent solvents or water used in the process. Moreover, the CO₂ the company uses is recycled CO₂ captured from industrial processes and therefore does not create additional greenhouse gases
