Vacuum Furnace

High Temperature Vacuum Furnace

This High Temperature Vacuum Furnace is a very cost-effective vacuum furnace. Max. vacuum up to 0.007 Pa. Low price, simple operation, excellent vacuum effect, good temperature field uniformity. It is used for high temperature vacuum sintering, annealing, tempering and aging treatment of ceramic materials, ceramic metal composites, refractory metals, and alloy materials, as well as vacuum brazing of alloy tools and superhard materials.

Vacuum Furnace Applications include:

  • Vacuum heat treatment – hardening, tempering and annealing
  • Vacuum brazing
  • Sintering
  • Degassing

 

Advantages of Vacuum Furnace:

  • No surface oxidation or discolouration
  • Minimal distortion
  • Flux free brazing
  • Repeatable quality
  • Clean, safe, quiet and efficient

 

3 types Furnace Chamber for optional
