Vacuum/Urethane Casting

Vacuum/Urethane Casting

A bridge between prototyping & production


Silicone Tooling/Vacuum Casting/Plastic Urethane Parts

Vacuum casting in conjunction with silicone tooling is the ideal way to create production-quality prototypes and end-use parts. It’s a quick, cost-effective solution to produce high-quality, cosmetic, and functional parts in production-like materials.

At GoProto, we start the process with a master pattern made using 3D printing or machining depending on tolerance needs. We then use that master to make a silicone rubber mould. We pour liquid urethane material under a precise vacuum into the mould. Once the urethane cures the part is removed and finished.

Because of vacuum casting’s ability to produce parts with textures quickly, it is a process worth investigating. GoProto can make the vacuum moulding and casting process a straightforward experience for you!
