Prototype (Soft) Tooling: RTV Moldmaking & Urethane Casting
RTV (room temperature vulcanizing) rubber is useful to create a quick and accurate mold from the master pattern.  
This allows for a small number of duplicate parts to be produced (up to 20 or so, depending on the complexity and
detail of the master).

A large range of urethane materials can be cast using such a tool.  These parts can range in hardness from 80-90
Shore D (rock hard) down to a 30 Shore A (nearly chewing gum).  Parts may be cast in opaque or clear, and tinted
for specific color ranges.  Urethane parts are durable and impervious to most solvents, and can accept standard
paint finishes and graphic applications.

  • Solid castings, "dump cast" parts are very thick solid parts, usually made in a single sided one piece mold.  
    This type of casting can be utilized as a painted visual model; or if unpainted, as a "tracing master" to be
    scanned or probe traced for creating your production tooling.

  • Thin wall castings can simulate injection molded components and housings.  These can be used to duplicate
    functional-visual, or engineering model components.

  • Simulated Roto-Mold products can be formed using our custom "Cold Form" roto-mold equipment.  
This produces a hollow urethane part, reducing weight and material cost.
Parts may be either rigid (tanks, containers, hollow rigid parts), or flexible (soft air bladders, or collapsible tanks)
depending upon the casting material chosen.
