UniTwin® hybrid surface treatment is a combination of a special plasma nitriding process with a subsequently applied hard coating.

 

Areas of use

  • Metal forming dies up to 500°C
  • Molds and transport elements for plastics
  • Die-casting tools

 

Material groups

  • Tool steels
  • Powder metallurgy materials
  • Special materials

The advantages

  • The supporting effect of the nitrided layer reduces the “eggshell effect” and reduces wear on the functional layer
  • Significant increase in the service life of tools and machines
  • Avoids abrasive and adhesive wear
  • Improves demolding characteristics
  • Very good coating adhesion
