Let’s talk some more details about vacuum casting.

This is a casting process for elastomers which uses a vacuum to draw any liquid material into the mold. Vacuum casting is used when air entrapment is a problem with the mold. Additionally, the process can be used when there are intricate details and undercuts on the mold.

Rubber – high flexibility.

ABS – high rigidity and strength.

Polypropylene and HDPR – high elasticity.

Polyamide and glass filled nylon – high rigidity.

High precision, fine detail: the silicone mold makes it possible to obtain parts totally faithful to the original model, even with the most complex geometries. … Prices and deadlines: the use of silicone for the mold allows a reduction of costs compared to an aluminum or steel molds.

Production Restriction: Vacuum casting is born for low volume production. The silicone mold has a short lifespan. It can produce as many as 50 parts.
