RTV Molding and Casting
We can turn your CAD files into beautiful, dimensionally accurate multiples very quickly, using the RTV molding process. Many material options are available, from soft elastomeric Shore A materials to rigid, fire-retardant Shore D materials. Below is a brief explanation of how the process works.
Master Pattern
We start by turning your CAD file in to a rigid master pattern, using either an SLA or PolyJet model printed on our equipment. The model is scaled to compensate for any potential shrinkage of the silicone mold, so that your end parts measure as close to nominal as possible.
Silicone Mold Creation
Your SLA is finished to your specifications, suspended inside a box, then surrounded with silicone rubber.
Preparation for Urethane Casting
The silicone is later cut in half, your SLA master is removed, and what remains is your mold, ready for urethanes.
Urethane Casting
Your prototypes are cast in the materials and colors you specify, ready for you to assemble, test, and show them off.
