Mold Making Tutorial: How To Make a Silicone Rubber Mold Using OOMOO 30

This mold making tutorial video shows how to make a one piece silicone block mold using OOMOO. The finished mold can be used for casting resin, wax, foam, and many other materials. In this video, we cast Smooth-Cast 300 liquid plastic and resin into the finished mold. OOMOO® 25 & 30 are easy to use silicone rubber compounds that feature convenient one-to-one by volume mix ratios (no scale necessary). Both have very low viscosity for easy mixing and pouring, and vacuum degassing is usually not necessary. B
