The Freeze Cast Process for casting precision automotive and other parts, freezes water in rubber molds to make temporary ice patterns that can be invested in ceramic slurries to make a shell that can be filled with any molten metal. The resulting precision casting will be of tight dimensional tolerance, exhibit excellent surface finish and reproduce intricate detail so that parts obtained will require little or no machining. Parts can be produced at 35-50% of the cost of competing precision casting processes such as Lost Wax and Lost Foam, competing in price with sand castings.
