Mould materials are also the basis of the mould industry. But even in the new mould material is difficult to meet the higher comprehensive performance requirements of the mould.

The material of mould is also the foundation of mould industry. But even in the new mould material is difficult to meet the mould's higher comprehensive performance requirements. Surface engineering is a more active and rapidly developing team in the field of materials science and engineering. With comprehensive, diverse, functional, innovative, protective and so on, as well as strong practicality and great efficiency, so also by all walks of life by the tube group. CrN chromium nitride coating in the production of moulds has been a great make up for the function of the mould material can not be achieved. We use this technology reasonably, can make the service life of the mould with low cost to improve a lot, then our economic profit came up, now, all kinds of mould surface treatment of new technology is getting more and more attention from the industry as well as the promotion of the application of the performance of the mould coating technology is the main purpose is to improve the performance of the mould, such as, hardness, abrasion and corrosion resistance, etc., fundamentally prolong the mould performance, such as, hardness, abrasion and corrosion resistance. The main purpose of the coating technology for mould performance is to improve the performance of the mould, such as hardness, wear resistance and corrosion resistance, etc., which fundamentally extends the service life of the mould.
Such coating technology has been widely used in the surface treatment of moulds. It also has good resistance to high temperature and oxidation, and CrN coating is well used in the mould field.
