Abstract
An apparatus and process for producing shaped metal parts of a semi-solid metal slurry. The metal slurry is introduced as a preform slug or ingot to a prechamber which is subjected to sufficient pressure to force a portion of the semi-solid metal slurry from the prechamber to a metal part shaping die cavity. The completed metal part, together with the portion of metal which remained in the prechamber during part formation, is removed and the metal which remained in the prechamber is detached from the final metal part.
