The process uses patterns or models produced on Rapid Prototyping systems such as Stereolithography to generate high-strength metal parts equivalent to those produced by pressure die casting in just a few hours. Small patterns or originals are layed out on a disc of uncured silicone to create casting cavities. When cured, this rubber mold is spun in a centrifuge while low temperature metals such as zinc, pewter, tin or lead are poured into the center of the mold. Silicone rubber molds can be cycled as many as 50-60 times per hour, for hundreds of cycles. Therefore, a 20 cavity mold can produce 1000 components per hour if small-to-medium production runs are needed. Resulting parts have excellent detail and representative surface finish of the master pattern. Production parts typically achieve tolerances in the ±.005 to .008 inch range. Investment Cast Wax Patterns, and Thermoset Plastic Injection Molded Parts can also be produced quickly using this duplication method.
