The material of the mold is also the foundation of the mold industry. But even in the new mold materials are difficult to meet the mold's higher comprehensive performance requirements. Surface engineering is a more active and rapidly developing team in the field of materials science and engineering. It has comprehensive, diversified, functional, innovative, protective and so on as well as strong practicality and great efficiency, so it can also be subjected to all walks of life by the tube group.CrN chromium nitride coating in the mold making has greatly made up for the function that the mold material can not reach. We use this technology reasonably, can make the service life of the mold at a lower cost to improve a lot, then our economic profits come up, now, a variety of mold 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 mold coating technology is the main purpose is to improve the performance of the mold, such as, hardness, abrasion and corrosion resistance, and so on, fundamentally extend the mold's performance, and so on, and so forth. etc., fundamentally extend the service life of the mold.
Such coating technology has been widely used in mold surface treatment. It also has very good resistance to high temperature and oxidation, and CrN coating is well used in the field of molds.
