Almost anything can be reproduced using silicone molding process. You can even reproduce light lenses for old cars and motorcycles.
On this page I will show you how to mold your own Rubber and Plastic parts.
Rubber parts can be duplicated by using Silicone Rubber for molds and then using one of several rubber compounds for forming the reproduction part.
This is useful when a part is just not available. You will however need at least one of the original part to make the silicone mold, unless you are creative and can make the master out of plaster or wood.
A vacuum Degasser is highly recommended, although not required for taking the bubbles out of mixed silicone compound.
