Vacuum Castings

What Is Vacuum Casting?

Vacuum casting involves making a mold out of silicone rubber, usually based upon a master model created by CNC machining or one of our rapid prototyping services. It is a low-cost but reliable way for making a low volume of high quality prototypes based on a master model. This highly versitile method uses cast silicone molds. It is undoubtedly the most economical production process for small series: prototype parts, pre-series. This method is ideal for rapid prototyping used in engineering testing, proof-of-concept and display demos to name a few.

Advantages Of Vacuum Casting

1) There is a low initial cost since it doesn’t require investment in tooling

2) The high fidelity of the mold gives excellent surface details requiring little or no post-processing

3) Many different molding polymers are available that can be pigmented to meet your color requirements

4) Molds can be ready in a few days once the master model has been created

5) Molds are durable up to approximately 50 copies so it’s great if you need more than one copy

6) We provide overmolding, so that different types and hardnesses of plastic can be molded together into a single unit

7) It is an excellent option for testing multiple variations of a prototype design for rapid product development
