Inthe RTV (Room Temperature Vulcanized) tooling process, liquid silicone rubberis poured around a master pattern. The master pattern/ mold usually originatesfrom Stereo Lithography as SL produces resin parts to a high degree of accuracywhich is capable of demonstrating mechanical fit and function. SL parts arefinished to a high standard to create tooling masters.
Theresulting mold is pulled/ cut from the pattern and cured, then subsequently usedto cast urethane parts. The key advantage of this process is being able toobtain 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
Can be used for low-run production in certain situations
Delivery of part (s) usually in 2 - 3 weeks
