Prop Making

Prop Making Techniques

 In this tutorial we explain the process of making a resin helmet. We molded a painted, Pepakura pattern. We used Gel-25 to make a 1 piece mold. To begin, we did a test cure on the pattern to make sure the Gel-25 would cure on our pattern. Once that was done, we made the mold. We built up the the mold in layers using TinThix thickener. TinThix is a chemical thickener for our silicones that converts pourable silicone into a brushable paste. Once the silicone mold was cured we built a plaster bandage support shell. We used EasyFlo 120 casting resin to "slosh" a hollow helmet. PolyColor Pigments and metal powder pigments can also be used to create color and metallic effects.

Foam is a very popular material for prop making. We offer both rigid and flexible foam systems. In this tutorial we explain some basic use tips for casting rigid foam into a silicone mold. For this cast we used our economical, Rigid Casting Foam and cast it into a PlatSil Gel-10 silicone mold. PolyColor pigments can be used to cast colored foam parts, Rigid foams can also be used to back hollow resin casts, like EasyFlo 120 rotationally cast parts.
