Vacuum Casting Materials

Vacuum casting technology is the ideal solution for manufacturing functional prototypes and short-run production with finishes identical to plastic injection molding. This section details the mechanical, thermal, and physical properties of our range of polyurethanes, transparent resins, and elastomers, making it easier to select the optimum material for every requirement of rigidity, flexibility, or impact behaviour.
