Dry ice cleaning for plastics and composites

Dry ice cleaning for plastics and composites tooling

Mold and tool surfaces can vary in finish, geometry, coating, and sensitivity. Identify the tool material, processing material, release products, and the effect the deposit has on production.

Information for project review

For a test, choose an area representative of the actual buildup and surface finish. Establish the inspection method and the condition needed before the tool returns to service.

Plan a representative assessment

A useful assessment addresses the residue, accessible area, target condition, air supply, ventilation, and collection of removed contamination. Test results should guide the final scope and scheduling discussion.

Choose the tooling application

Use plastic injection mold cleaning for injection tooling, rubber mold cleaning for rubber-process deposits, and composite tool cleaning for composite tooling and release systems.

Identify the tool material, finish, operating conditions, and cleaning history. A proposed tooling program should keep each tool’s inspection points and restrictions attached to its identifier, even when several tools are serviced in one visit.

Plan the initial work and the repeat scope

Supply the asset list, photos, target condition, location, and available hours. Use a defined test cleaning where the deposit or surface response needs evaluation.

Connect the result to scheduled maintenance or shutdown cleaning. Review pricing and scope with the preparation, collection, inspection, and release responsibilities identified.
