RTV Tooling (Room Temperature Vulcanization)

This type of tooling provides cost and time effective solutions for higher quantities of prototypes in a variety of materials that closely match most thermo plastics. RTV tooling can produce up to 40 parts per mold at a production rate of 1-10 parts a day. Cast urethane materials can mimic production parts in material & thermal properties, surface texture and color.

The (RTV) Tooling Process

A (FDM) Prototype Is used as the master patter in which the (RTV) tool will be created from. This master pattern will be finished off to a high level finish. A parting line will be established and a follow board will be created. The liquid (RTV) rubber is poured over the pattern and follow board. After the rubber has hardened. the follow board is removed a parting film applied and the second half of the mold is poured. The master pattern is removed from the two halves of the mold.

Now liquid urethane resin is injected or vacuum assisted in to the mold. The urethane solidifies and the part is removed.

Cast prototypes are typically used for the following:
