Investment casting is a manufacturing process in which a refractory ceramic material is applied to a wax pattern. Once the ceramic coating material dries and hardens, the wax melts and leaves an internal cavity of the final product geometry. Molten metal is poured into the cavity where the wax pattern sits. The metal solidifies in the ceramic cavity, cools, and the ceramic is removed from the metal casting. The result of this process is a clean to near-clean precision metal component that can be used in a wide variety of applicatio...
