Dry Ice Blasting Reduces Line Downtime over Conventional Cleaning

Dry ice blasting has revolutionized mold cleaning in the plastics industry. By cleaning “in place” and while the mold is hot, production downtime can be substantially reduced, allowing greater profitability.

Dry ice blast cleaning removes the build-up of surface residue from the product mix, including release agents, overspray’s, and other molding process by products faster and more effectively than traditional cleaning methods. Even heavy build-up can be removed with dry ice blasting and because dry ice sublimates, there is no secondary waste, minimizing clean up.

Dry ice blasting is a dry cleaning process that is environmentally friendly and non-abrasive, allowing increased cycles between preventive maintenance schedules.

Mold Cleaning Examples Include:

Core Boxes

Dry ice blasting reduces production line downtime because equipment can be cleaned while still hot.

Dry ice blasting is used to clean mold release agents, removing residue that can cause mold fouling and lubbers. No added solvents or water are needed and dry ice leaves no residue. Dry ice also cleans slot and screen vents at the same time. Cleaning with dry ice does not damage the molds or distort their shape, so productive life is increased.

Plastic Molds

Clean built-up residue from release agents and other molding byproducts with dry ice blasting. Dry ice blasting removes hardened plastic, mold release agents, and plastic build-up. Dry ice blasting does not require solvents or disassembling molds or work transfer systems. Dry ice blast cleaning leaves a smooth surface, preventing damage to the finished product surface, thus lowering waste and scrap costs.
