Rubber Plaster Casting - Rapid Prototyping - Rapid Tooling

Rubber plaster casting is used to manufacture highly complex aluminum components that require a higher surface finish then sand casting can provide. Rubber Plaster casting is perfect for components which surface finish must closely simulate that of die cast parts. In this process, LOM parts are used as patterns around which a rubber sheet is pulled. Plaster is packed into the rubber sheet which is then removed. Next, metal is poured into the plaster cavity which is later broken away to expose the metal part.
