What is Compression Molding? | TranPak

Compression Molding. Compression molding is the process of molding in which a preheated polymer is placed into an open, heated mold cavity. The mold is then closed with a top plug and compressed in order to have the material contact all areas of the mold. This process is able to produce parts with a wide array of lengths, thicknesses, and complexities.
