Vacuum Casting

Why vacuum casting?

When your brief is for pre-launch testing, low volume manufacture of simple parts or concept models and prototypes, you want a reliable, cost-effective alternative to injection moulding.

Vacuum casting fits that bill. Tooling starts with a 3D printed master pattern, and the tool itself comprises silicone. Both of these phases are fast and economical. The resultant parts are high-quality, and their attributes are comparable to injection-moulded parts and can be formed with very tight tolerances. The process lends itself well to a variety of finishes, including colour options and texturing.

We want to help you to keep your prototyping costs down without compromising on quality. We have a dedicated vacuum casting facility with multiple machines and myriad rigid and flexible materials, including those with high temperature, V0 rated flame retardant, UV stability, glass-filled, and food-safe properties. It’s our mission to deliver on quick turnaround times, exceptional quality and outstanding levels of customer service.
