Vacuum casting is used

to make prototypes and small series, close to end materials in few days.

With this process we can make overmolding parts (plactics and metal inserts) with certifications as UL94, FDA, FAR25.

The silicon tool life is between 15 and 20 parts depends of geometries and resin used.
