Unlike cutting tools, most shaping tools are still uncoated. The main reason for this is the larger sizes and complex shapes of the tools, which can make it challenging to ensure good adhesion between the substrate and the PVD coating. Nevertheless, in recent times, coating methods and types of coatings with excellent tribological properties have been established, which significantly improve the adhesion (forming of aluminum alloys and stainless steel) and abrasion (high-strength steels) wear resistance of forming tools.

CrN A coating that will protect your tool against oxidation. At the same time, this coating is suitable for all-round processing of copper. Coating can also be applied to tools at a temperature of around 200 °C. Pošljite povpraševanje Advantages Properties Applications Advantages Smooth coating and low coefficient of friction and bonding → Enables better gliding without sticking the material on the tool CrN-based coating → Provides excellent tool protection against oxidation while providing excellent adhesion Higher coating hardness → protection against wear and tool damage Properties Based on CrN Color: white-gray Nano hardness: 22+-3 GPa Coefficient of friction: ~0.5 Maximum processing temperature > 700 °C Coating can also be applied at lower temperatures Applications Use in copper applications Pressure injection moulding of plastic materials
