Compression molding is a manufacturing process in which composite materials are sandwiched between two matching molds under intense pressure and heat (from 150° to 200° C) until the part cures. This technique is used to rapidly cure large quantities of complex fiberglass-reinforced polymer parts. Compression molding features fast molding cycles and high part uniformity. The process can be automated. In addition, labor costs are low and it provides design flexibility and nice surface finishes.
