DUPLEX Treatment.
Our DUPLEX treatment consists of a thermo-chemical process (plasma nitriding), combined with the deposition of an Eifeler PVD coat immediately afterwards. This combined method (two steps in one process) yields a defined increase in surface hardness of the tool material. Therefore, it significantly improves the PVD coating’s performance.
Alternative to CVD Coating
DUPLEX has established itself as an efficient alternative to CVD coating, particularly in the area of forming high-strength sheet metal and with low tool tolerances. Not least due to the significantly shorter processing and delivery times of two to five working days.

Extreme Endurance
The DUPLEX treatment leads to a defined increase in the surface hardness of the tool material. This results in numerous positive effects. For example, the increased performance of the PVD coating results in significantly higher endurance as well as considerably reduced set-up and tool costs.

Advantages of the DUPLEX Treatment
In the course of the DUPLEX treatment, the ideal formation of a hardness gradient happens from the tool’s core over the edge area to the tool’s surface. This and the fact that the coating temperature is below 500° C yields numerous positive effects – e.g. for the machining of high-tensile sheet metal.
- Increased supporting effect for PVD hard coatings
- Significantly improved absorbing power against compressive stress
- High-gloss polish remains intact
- Tool’s accuracy is retained
- Significantly improved endurance
- Lower set-up and tool costs
Surface Polish for Optimum Preparation
Optimally preparing a surface is essential for the maximum performance and excellent surface quality the DUPLEX method offers. This is why we naturally rely on the latest technology when it comes to pre-treatment systems. If required, we will process an additional surface polishing for truly special needs. Information on this is available under “Special surface polish” in the Services menu section.
For punching and forming tools
All coatable and nitritable steel materials are suited for DUPLEX treatment. This method is already well-established in the field of tools for the forming of high-strength sheet metal materials as well as the fields of deep drawing, punching, bending and pressing. In these areas, DUPLEX yields extremely high endurance. DUPLEX is regularly and successfully selected for tools for forming high-strength sheet materials. This is usually combined with the VARIANTIC coating system
