Vacuum investment casting is the process used in lost-wax technique to get a metal replica from wax or resin patterns.
The pattern is designed and then built in wax or resin by different equipment as CNC, 3D printers, by means of wax injection in a mould, or even manually.
You may use either investment molds or metal permanent molds.
Furnaces or complete foundries setup for casting of Au, Ag, Pt or Pd alloys can be supplied for any application, including vacuum melting into permanent molds.
