Coatings for moulding and forming tools
Coatings for molding tools have to meet different requirements compared to coatings for cutting tools - especially important to them besides hardness are smoothness, high elasticity and low coefficient of friction. For this purpose have been developed multilayer coatings based on titanium and chromium compounds with up to 40 layers. It is also possible to apply nanolaminatеs.
For processing of plastics For some of these it is important to provide a low sticking probability (anti-sticking coatings) - for example, the injection of certain types of molding plastics with high coefficient of thermal compression. In this case, the most suitable are carbon-based nanocomposite multilayer coatings with the last layer of non-hydrogenated amorphous carbon. These coatings allow to increase the speed of injection and hence the productivity by 10-15% depending on the operating mode.
