In addition to two-part resin molding, silicone cavities also are suitable for low-pressure injection molding of waxes for investment casting.

Using a low pressure, injection system, semi-molten wax is forced into the silicone cavity until full. The cavity is then chilled until the wax has fully solidified. The wax is then removed from the cavity and the process repeated. However, due to the fragility of the investment casting wax material, extreme care must be exercised when removing wax parts from the silicone tool.

   The advantages of RTV silicone rubber tooling is that it is quick to produce, reproduces detail impressively well and it's fast for producing a limited number of plastic parts. Disadvantages are poor tool life, cost of silicone rubber and lengthy cycle time. Also, it does not use the final production material (except for wax) or final manufacturing process.
