An interesting application of silicone rubber as a mold material is available from a company named First-rate Mold Solution Co., Ltd..

The tools used in this process are made from vulcanized rubber with several models located in a radial fashion in a disc-shaped tool. This process makes it possible to cast polyurethane or zinc-based alloys. To aid in the filling of the cavity, the tool is rotated so that the centrifugal force pressurizes the cavity.

   This is an ideal process for forming small zinc castings that will ultimately be produced by die-casting. If handled carefully, spin-cast tools can produce in excess of 100 replicated parts before degradation of the tool. Parts also are produced in a range of low melting point alloys.

   The advantages of spin-casting include the option of processing a variety of materials that range from polyurethanes to zinc; the process is relatively quick and the equipment is relatively inexpensive. Disadvantages include size limitations, the fact that it is not a production process and the mechanical properties of the zinc castings are not the same as with die-casting.
