Vacuum Casting

Vacuum casting of polyurethane resins offers many significant advantages.
Silicone rubber or resin tooling can mean that production representative parts in as little as 2-3 working days from approval of a master model.

The wide range of polyurethane resins available enables a good match with production intent material, including clear, tinted, ABS, Nylon, PP, PC and various filled plastics. Properties such as high heat resistance (to over 200 deg C) and flame retardant ( UL4 V0 rated) can also be accommodated.

An extensive range of elastomers are also available from 25 to 95 shore A harness. These can be coloured to suite or even clear.

Intricate components can be produced with wall thicknesses down to 0.5mm. Similarly, the route can be used for complex insert mouldings and even two shot overmoulded parts.

Because of the low tooling cost relative to injection moulding, vacuum casting can be the ideal solution for low volume production runs.
