Rigid Vacuum Casting Materials

A large range of material properties are available from ARRK with our vacuum casting process. Examples include ABS-like and clear to fire retardant prototypes, cast in UL94V0 rated urethane, and semi-rigid prototypes which emulate the properties of polypropylene. The latter is particularly suited to prototypes of automotive trim and casings for hand tools. The resins can be colored to a wide range of shades, and ARRK will match pigments for Pantones and RAL classifications or customer’s samples on request.
