Aerospace: Vacuum Furnaces

By Furnace Engineering

Furnace Engineering together with Ipsen International offers a wide range of Vacuum Furnaces for a variety of heat treatment processes including:

  • Bright hardening, annealing, tempering
  • Hard and high-temperature soldering
  • Solution annealing
  • Degassing
  • SolNit®
  • AvaC® (low-pressure carburising)
  • Plasma nitriding & carburising
  • Sintering

The Ipsen Furnaces are designed for cost-effective operation. The low energy consumption and emission comply with strict environmental standards. 


The key benefits are:

  • Optimum hardness
  • Bright surfaces
  • Surface layers free from oxidation and decarburisation
  • Low distortion also for complex geometries
  • Consistently high quality
  • Reproducibility
  • Suitable for a wide variety of materials

Different types of horizontal & vertical single or multi-chamber furnaces are available. They can be fitted with convection-type systems for increasin throughput by reducing heat-up time and ensuring optimum temperature homogeneity.

The vacuum furnaces can also be fitted with the Ipsen convective heating system. This can reduce heating time by 30% (for convective heat transfer up to 850°C) and shortening subsequent tempering cycles by up to 50%. Further, gas consumption is reduced as quenching gas is used as convective heat transfer medium during tempering.
