Rubber molds are one of the fastest ways to create short run prototype and limited production run parts. Parts produced are used for functional prototypes as well as marketing models.
The rubber mold is created from a master pattern, typically an RP model. The pattern is used to create a silicone rubber mold. The silicone is poured around the pattern to produce a core and cavity of a mold. The RP model is then removed, leaving a negative image into which polyurethane is cast. These molds can produce up to dozens of parts per mold, and they can be made as family or multi-cavity molds.
Urethane casting material is commonly used for product prototypes. Urethane can be formulated to have material properties similar to elastomers or ABS with material properties, color, and surface texture very similar to that of production materials.
• Excellent surface quality and detail
• Fast turn around, Low cost
• Functional Prototypes Similar to Production
• Marketing Models
