Semi-Custom ultra precise molds are designed to exacting standards for professional use. Very small jigs require molds made to extremely tight tolerances. These molds are completely machined from our blank mold frame using a computer-controlled mill. Each cavity, hook receptacle and pouring gate is individually milled to perfect alignment and fit. Pouring gates are designed for the professional with minimum opening to permit quick and clean sprue twist off. Minimum gates make pressure casting from a bottom-pour lead furnace mandatory with these molds. Semi-Custom models are exceptionally accurate and precise. The investment in these molds can be quickly recovered through increased productivity when producing small jigs in commercial quantities.

WARNING: Melting lead and casting lead objects will expose you and others in the area to lead which is known to cause birth defects, other reproductive harm, and cancer. See instructions on Reducing Exposure supplied with product. - www.P65Warnings.ca.gov.
