Vacuum Casting services

Some resins can be colored to a wide range of shades, and ARRK will match pigments for Pantones, classifications or customers' swatches on request.

An increased range of material properties is now available following the introduction of new resins at ARRK. Examples include fire retardant prototypes, cast in UL94V0 FR25 rated polyurethane, and semi-rigid prototypes which emulate the properties of polypropylene. The latter is particularly suited to use for prototypes of automotive trim and casings for hand tools.

These may be textured, polished and/or colored according to customer requirements. This method provides prototypes which resemble the final product not only in shape, but also in appearance and feel, so providing for visual as well as practical appraisal. In turn, these prototypes can prove extremely valuable for early market testing.

ARRK's vacuum casting service gives you access to high quality, low volume reproductions of StereoLithography prototypes in a variety of polyurethane resins.
