HARD-MATERIAL COATING

With correct application, our CVD, PVD and PA-CVD coating processes guarantee significant extension of service duration and contribute towards improvement of slide and anti-friction properties for tools under abrasive loads.


For detailed information, please see our more info section or our download area. There, you can also gain an overview and learn more about our coatings, heat treatment processes and services.


CVD (CHEMICAL VAPOUR DEPOSITION)

Highest degree of hardness and adhesion strength

  • Extension of service life, even for processing of high-strength metal sheets
  • Also for tools with close tolerances
  • Special performance increase in combination with CHOHPlus
  • and other special materials

 

Fields of application:

  • Cold-forming tools
  • Heavy-duty tools
  • Hard-metal tools
  • Solid forming

PVD (PHYSICAL VAPOUR DEPOSITION)

Highly efficient coating without changes in shape and dimension

  • Protection against abrasion and adhesion on the tool
  • Improved connection of coating due to duplex process
  • Protection of tools and reduction of adhesions in plastics processing
  • Head-start advantage due to continuous improvement of coat systems

 

Fields of application:

  • Metal sheet forming
  • Cold solid forming tools
  • Aluminium & non-ferrous metal processing
  • Punching and metal cutting tools
  • Plastics processing (polymer processing)

PA-CVD (PLASMA-ASSISTED CHEMICAL VAPOUR DEPOSITION)

Optimum cost advantages

  • Coating of complicated geometries
  • New coat systems for special applications (hydroforming, mould construction, aluminium die-casting)
  • Cost-effective coating, even of large tools

 


Fields of application:

  • Plastics processing
  • Metal sheet forming
  • Aluminium processing
  • Die-casting
  • High-temperature applications
  • Hot forming
  • Extrusion moulding
