Compression molding is a developed process in which the molding material is placed in an open, heated mold cavity. The mold is typically made from machined steel that will permit a long service life. The mold is then closed with extreme pressure to force the fiber and resin compound in to contact with all areas of the mold cavity. Pressure and heat are maintained until the molding material has cured. The process employs thermosetting resins with short or long chopped fibers, known as random mat and/or performs of continuous fiber for additional part strength. A distinct advantage of compression molding is its’ ability to mold tiny to giant complex parts with features such as holes that would otherwise must be post-machined with other processes.
