What Is Vacuum Casting?

Polyurethane vacuum casting is a specialized technique for making high-fidelity copies of master patterns using inexpensive silicone molds and pourable casting resins. Copies made in this way demonstrate the same quality as plastic injection molded parts while taking only a fraction of the time and expense to produce.

Advantages Of Vacuum Casting

Low cost for molds

Molds can be made in a few days

Many types of polyurethane resins are available for casting, including overmolding

Cast copies are highly accurate with excellent surface texture

Molds are durable for 20 or more copies

Perfect for engineering models, samples, rapid prototypes, bridge to production
