For Small Series With Big Impact

Vacuum Casting is a copying technique used for the production of small series of functional plastic parts. Using two-component polyurethanes and silicone moulds, Vacuum Casting is known for its fast production of high-quality prototypes or end-use products.

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

Ideal Applications For Vacuum Casting

  • Pre-launch product testing

  • Small series of housings and covers

  • Concept models and prototypes


Rubber, PP, ABS, and PC


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.
