Why Dry-Ice for Shoe-Mold Dry Ice Cleaning?
Footwear molds accumulate release agents and compound residue that dull surface detail and drive defects like flash, shorts, and poor fill. Traditional scraping, solvents, and bead-blast are slow, abrasive, and force extended change-overs.
Dry-ice blasting accelerates 3 mm CO₂ pellets to high velocity. On impact, they flash-sublimate—creating thermal and acoustic micro-impulses that shear residue from aluminum or steel without abrasion, moisture, or conductivity.
Cleaning in place preserves micro-textures and emboss, reduces solvents and wet waste, and returns the press to production in minutes—improving first-pass yield and OEE while extending mold life.

Core Benefits
Clean in place
Eliminate cool-down, crane moves, and re-alignment to reclaim production time.
Protect fine detail
CO₂ (~2 Mohs) avoids peening; preserves micro-textures, logos, and date codes.
Zero media cleanup
CO₂ vaporizes on impact—no grit, slurry, or wastewater handling.
Stabilize first-pass yield
Reduce flash/shorts and improve fill consistency with cleaner cavities.
Reduce solvents
Remove release agent buildup without chemicals; improve EHS and indoor air quality.
Safer ergonomics
No scraping or harsh chemicals—lower risk to operators and equipment.
Planable maintenance
Short, repeatable cycles slot neatly into mold-change windows.
Lower total cost
Extend mold life and reduce unplanned downtime and consumables.

“We stopped solvent scrubs and kept molds on the press. Texture stays crisp, defects dropped, and we regained an hour every change-over.”
