Plain Compression Molding
The molding material is placed in an open, heated mold cavity. Then, the mold is clamped and the clamping force is applied to the material to build up the necessary molding pressure. Heat and pressure are maintained until the molding material has cured. Parts can be trimmed in a secondary operation. Compression molding is a high-volume, high-pressure method, well recommended for large shot size parts, of non critical dimensions, using long cured compounds.
