Eliminate Mold Release Buildup Without Removing Your Tools – Dry Ice Cleaning Saves Hours

Injection molding and plastic extrusion are high-precision processes. Even microscopic residue – mold release agents, polymer buildup, carbon deposits – causes defects, flash, and rejects. Traditional cleaning requires removing the mold, soaking it in chemicals or using hand tools. That means hours or days of lost production.

A dry ice cleaning machine changes everything.

Clean molds in place – without cooling down?

Yes. Dry ice blasting can be applied to warm molds (up to 300°F). Because the process uses thermal shock, warm molds often clean faster than cold ones. No need to remove the tool from the press.

Key benefits for molders and extruders:

60–90% less downtime – Clean in 30 minutes instead of 4 hours

No abrasive damage – Preserves critical tolerances and polished surfaces

No disassembly – Eliminates reinstallation errors and alignment issues

No chemicals – Safer for operators and no hazardous waste disposal

Vent and rib cleaning – Reaches deep channels that brushes can't touch

Real results from the plastics industry:

A medical device molder reduced mold cleaning time from 3 hours (using ultrasonic and hand polishing) to 25 minutes with dry ice. Annual production increased by 480 hours – equivalent to adding 20 shifts per year.
