FAB107: Silicone RTV Moldmaking and Casting Basics
Class Number 313-47791

Learn how to work with silicone RTV (room temperature vulcanization), make a small mold, see how more advanced molds are made, and even cast your own part in urethane resin!

In this introductory class, you will learn to make a silicone RTV mold from a small part or pre-made plug. You will make a single-sided mold of a quarter or other small, simple part. You will also examine two-sided mold making, adding registration "buttons" and slicing the mold. You will then cast resin in an RTV mold, learning tips and tricks to mixing and pouring resin and other substances to create final pieces from a silicone RTV mold.
