Vacuum Casting
ARRK's vacuum casting service gives you access to high quality, low volume reproductions of StereoLithography prototypes in a variety of polyurethane resins.
These may be textured, polished and/or coloured according to customer requirements. Latest additions to the range of finishes include leather-look and walnut finish. 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.
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 rated polyurethane, and semi-rigid prototypes which emulate the properties of filled polypropylene. The latter is particularly suited to use for prototypes of automotive trim and casings for hand tools.
The resins can be coloured to a wide range of shades, and ARRK will match pigments for Pantones, RAL and BS classifications or customers swatches on request.
