vacuum casting process
How Does Vacuum Casting Work?
Vacuum Casting begins by producing a master model, typically using Stereolithography or Laser Sintering, with a high-quality surface finish. Then a silicone mold is produced by casting silicone around the master copy, partially under vacuum to avoid air bubbles. After curing, the silicone mold is cut according to pre-defined parting planes and the master is removed, leaving a cavity to make copies.
Why choose Vacuum Casting?
Silicone molding results in high-quality parts comparable to injection-molded components. This makes vacuum casted models especially suitable for fit and function testing, marketing purposes or a series of final parts in limited quantities. Vacuum Casting also lends itself well to a variety of finishing degrees, and we can match the finish you need for your parts.

Materials for Vacuum Casting
We offer an exceptional range of 26 carefully selected polyurethanes that are similar to rubber, PP, ABS and PC. These materials provide an outstanding variety of properties, and offer the possibility to match colors and cast transparent components. If you are looking for a specific finish, our skilled post-production team for Vacuum Casting will match your requirements.
Regularly if one new product is develop by prototyping , and it’s not under the process of mass production, but also needed a small quantity products to sell in the market , the best choice to save cost from molding is to do the rapid prototyping , use silicone mold (or aluminum mold) to produce small quantity for the trial-produce , or has small quantity products as sample . (silicone rapid prototyping).
