What is Vacuum Casting?

It is a casting process for elastomers using a vacuum to draw the liquid material into the mold. The process starts by placing two pieces of silicon mold in a vacuum chamber. The raw material is mixed and degassed and then poured into the mold.

Firstly, a master model is made by CNC or SLA and polished to the final surface finish of the part for Silicone Rubber Mold making. Normally, one Silicone Rubber Mold can produce up to about 15 parts and it depends on the design complexity of the part and casting material. Many materials with simulant properties of real engineering plastic materials are available for vacuum casting. We can duplicate the product in a range of different plastic simulant materials, PX5210, PX223, UP 8150, UP 8260, UP4280, UP5290, etc.

Urethane casting provides end-use, rigid or flexible plastic parts with production-level quality. Built without expensive and time-consuming hard tooling.

Our casting process is optimal for low-volume production for quantities of one to several hundred.
