Abstract
Reverse gating is added to a conventional compression molding machine so that when the molding cavity is filled with material in excess of the amount required to mold a part, the material flows from the cavity to a pressure chamber to be vented. Pressure in the chamber allows back flow of the material from the chamber to the molding cavity during cooling to compensate for shrinkage.
