Vacuum Melting & Casting

Ferrous Metals

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 the casting of Steel, Fe and Nickel-based alloys can be supplied for any application.

For rapid prototyping of parts in steel, nickel alloys used for example in the aerospace, automotive and medical, TOPCAST offers:
  • TVC-XL vacuum casting machines (dual chamber system) to get detailed and porosity-free surfaces;
  • TCE furnaces vacuum centrifugal casting for high high metal yelds, thin and large surfaces, difficult and detailed parts;
  • TVM - Vacuum Induction Melting Furnace (VIM) pouring by gravity, either from a cold crucible (skull melting) per pristine meltings, or hot crucible when you need overheating and high energy efficiency;
  • FCC furnaces for wax / resin removal and refractory mould baking.
