Our engineering team designs the most adequate configuration for your heat treat process while using state-of-the-art CAD programs and load calculation simulations. The customized systems usually consist of following materials and coatings:



CFC Charging elements and systems for high-temperature applications

NKCG systems are being used in several applications such as:

  • Carburizing
  • Sintering
  • Vacuum Brazing
  • Intert gas and vacuum atmospheres

Key advantages of CFC


  • Low thermal mass allows rapid heat up and cool down
  • Reduction of energy during each cycle
  • Increased load capacity
  • Option to repair spare parts of a rack & recoating
  • Less weight = less danger due to handling accidents
  • Mechanical strength increases with temperature
  • Improving the quality of the treatment result with precision load arrangement
  • High stability while being resistant to thermal shock (no deformation)
  • C/C systems are not susceptible to fatigue
  • Combination of stainless steel based charging plate and CFC load system possible
  • Custom design for your specific application – optimizes your process
