Compression molding is a method of molding in which a precise quantity of molding compound containing thermosetting or elastomeric resin called a charge is placed in the bottom half of a heated mold cavity, then flows to fill the cavity as the 2 sides of the mold are pressed together. The heat causes the material to polymerize and solidify, after which it can be removed as a solid part.
