Automated, CO2-Based Blast Systems Specializes in Cleaning Mold Surfaces

Cool Clean Technologies, utilizing CO₂-based technology, has shifted its focus from gentle CO₂ spray cleaning solutions to incorporate a powerful, blast cleaning product to clean various surfaces, molds and tools. The company’s Omega CO₂ cleaning solutions specialize in cleaning mirrored finishes and micro molds, by removing thin films, residues and oils from the mold surface that create defects on a molded part.

According to the company, what sets Cool Clean’s system apart from a traditional dry ice blaster, is that it does not require pellets or blocks of dry ice to operate. The Omega CO₂ cleaner produces dry ice from a high-pressure gas or liquid CO₂ source by expansion to create the CO₂ crystals used to clean the molds.

Automation has been a challenge for dry ice blasting because the perishable supply of dry ice pellets or blocks needs to be manually reloaded into the equipment continually during operation. Alternately, Cool Clean’s system’s CO₂ supply is nonperishable and contained in a cylinder or tank for on-demand, continuous cleaning.

Moreover, Cool Clean contends that its cleaning solutions reduce the downtime of injection molding machines as they can be cleaned in place without being dismantled for offline cleaning. The Omega operates at a low-level noise and quickly removes residues from the mold with ease, while leaving behind no residue or condensation.
