Urethane casting

Cast Urethanes, RTV Molding and Polyurethanes (Polys) all refer to a low volume production method that produces parts from a Polyurethane plastic material for prototyping purposes. 

These parts have material properties similar to production-like plastics. It is possible to make these parts appear just like hard tooled plastic parts through surface finish, color, accuracy, and material properties.
Cast Urethanes are ideal for marketing samples, test prototypes, or other situations where 1-100 pieces are required, but time and money do not allow a prototype injection-molded tool to be produced.
