Vacuum Casting is a copying technique used for the production of small series of functional plastic parts. Using two-component polyurethanes and silicone molds, 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.

For both beginners and veteran professionals, vacuum casting offers numerous benefits. Here are some of the most prominent ones:
Think beyond typical applications like creating transmission components or decorative parts. With so many inherent advantages, vacuum casting finds use in various industries.
The aerospace domain is one of the most demanding for quality and accuracy. It is where vacuum casting shines with its ability to create high-quality products with precision.
The medical industry is another sector that requires utmost precision and accuracy. Vacuum casting helps medical device manufacturers create body parts replicas with ease. These parts are used in training medical professionals and carrying out research activities.
The automotive industry is one of the leading adopters of vacuum casting. It is because vacuum casting helps manufacturers to create high-quality components quickly and economically.
The consumer goods industry is where the aesthetics of a product play a key role in its success. For example, vacuum casting helps manufacturers create replicas of expensive or intricate designs quickly and easily.
Vacuum casting is widely used in the electronics industry for creating a broad range of insulation components in bulk and at affordable pricing.
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.
