Injection molds develop resin buildup, mold release residue, and carbon deposits in fine detail areas and vents, and abrasive cleaning methods risk damaging the precision-machined mold surface and vent channels.

How Dry Ice Blasting Helps

• Non-abrasive blasting removes resin and carbon buildup without altering the mold's precision surface finish or dimensions.
• Clears fine detail areas, vents, and cooling channels that manual scraping and brushing can't fully reach.
• Molds can often be cleaned in place on the press, cutting changeover time between production runs.
• No water or media residue left in vents that could cause defects in the next molding cycle.

Because mold surface finish directly affects part quality, the non-abrasive nature of dry ice blasting makes it a preferred cleaning method for injection molders.
