Rubber Compression Molding Process

Compression molding involves pre-forming uncured rubber into a specified shape and weight that is put into a mold cavity. When the mold is closed, two plates put pressure on the elastomer, which then fills the cavity. The elastomer is maintained under pressure and heated until the rubber is cured, allowing the part to maintain its shape. Compression molding can be used for different production volumes and applications, including precision parts. Compression molding also can be used for insert molding and over-molding.
