There are several types of compression molding that are defined by the type of material molded: sheet molding compound (SMC), bulk molding compound (BMC), Glass Mat Reinforced (GMT). Compression molding tooling consists of heated metal molds mounted in large hydraulic presses. The process can be automated. Compression molding enables part design flexibility and features such as inserts, ribs, bosses, and attachments. Good surface finishes are obtainable, contributing to lower part finishing costs. Subsequent trimming and machining operations are minimized in compression molding and labor costs are low.
