Vacuum Furnaces

Vacuum Heat Treatment

Vacuum Technology is the Basis for Process Innovation in Heat Treatment. Heat Treatment is the process in which metallic/steel parts are exposed completely or partially to time- temperature sequences in order to change the mechanical and/or corrosion properties.

We cater into application areas like
  • Annealing
  • Hardening
  • Tempering
  • Aging
  • Case hardening

Advantages of Vacuum Heat Treatment

Vacuum as "Protective Atmosphere"
  • No toxic protective gases containing CO
  • No health hazards in the work shop
  • No danger of explosion or open flames
  • No furnace conditioning
  • Use of inert gases (nitrogen or helium)
  • No C02 emission

Vacuum Carburizing

  • Use of various processes
  • Use of different gases
  • Shorter carburizing cycles than in conventional technology
  • Higher carburizing temperatures offer potential to further reduce process time
  • Small gas consumption I instead of m3

Gas Quenching Instead of Oil Quenching

  • Clean, dry parts after hardening
  • No washing machine - no disposal of washing water
  • No maintenance of washing equipment
  • No complicated washing water chemistry
  • Saves space
  • Quenching intensity is controlled via gas pressure or gas velocity
  • Cost benefits
  • No vapor blankets during quenching
  • Homogeneous quenching
  • Reduced distortion Surface Influences
  • Free of surface oxidation
  • No surface decarburization
  • Bright, metallic, shiny parts

Our Heat Treat Furnace contains a usable zone of 3 cubic feet (841) and as our other heat treat furnaces, is capable of temperatures up to 1200C. With an 100 kg load limit, it features a medium load capacity. The unit shown here features a 1000 Ipm Rotary Pump with 8500 Ipm Booster pump, and gas heat exchanger for rapid cooling. The hot zone features graphite heating elements, insuring excellent uniformity, longevity, and product compatibility
