ABSTRACT:
An apparatus and method for automated casting of an item such as a plumbing fixture is disclosed. Female and male mold portions provide a spacing for molding the desired item between them. A fluid release system is operatively positioned inside one of the mold portions so as to assist in separating the formed item from a mold portion in a controlled and uniform manner so as to minimize damage to the cast item. In a preferred form, a liquid is ejected into the corners of a male mold. By diffusion the liquid travels to the periphery of the mold piece so as to drive the formed part off the mold.
