Molds are made by pouring liquid silicone rubber over a pattern. The resulting firm but flexible mold can reproduce extremely complex geometry and intricate detail with tight tolerances. The molding process uses urethane thermoset materials that are available with mechanical, thermal, and electrical properties. The resulting parts created with Polyjet molds exhibit characteristics of mass-production, molded parts with subtle details and precision accuracy. LSR molding is ideal for functional testing and applications producing under 100 parts in volume, making it the perfect alternative to conventional techniques.
