RTV Silicone Tooling/Cast Urethane Production

In the RTV (Room Temperature Vulcanized) tooling process, liquid silicone rubber is poured around a master pattern. The resulting mold is pulled from the pattern and cured, then subsequently used to cast urethane parts. The key advantage of this process is being able to obtain higher quantities of prototypes at relatively low cost.

• Functional prototypes and visual models with good detail and surface finishing
• Cast urethanes ranging greatly in rigidity, temperature tolerance, color and texture
• Accuracy within thousandths of an inch
• Can be used for low-run production in certain situations
• Delivery of part(s) usually in 2 - 3 weeks
