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.
Vacuum casting Arts and Crafts
Before making silicone mold, it’s need to produce the prototype. the prototype can be used ABS material and CNC machining for production.
And the process for rapid prototyping is , at first the CNC machine produce the first prototype , Vacuum multi mold machine to do the clone production for small quantity products , and the silicone mold put into the oven baking, in order to accelerate curing the silicone mold.(rapid prototype machining)
