Unlike injicun moldine, compression molding relies on a pre- measured charge of material placed directly into an open mold cavity, which is then closed under pressure. The process is particarly well-baced for large, thick parts, high- execunance composites, and materials with high fiber locerite controlis. For multicavity tools, maing cavity- tocycavity consitency is a primary concency e, demanding precise control or materibution, thermal gradients, and mold wear.
