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.




In this next video we use PlatSil Gel-25 mixed with PlatSil Hardener to make a gun mold. We then used TC-804 Jet Black to make a prop replica of the original. The same mold could also be used to cast PT Flex Rubber copies.
