√The coating with high aluminum content usually has high temperature resistance, which can maintain the original hardness and chemical characteristics at high temperature, so it is suitable for hot working die, such as AlCrN coating, AlTiN coating and alcrtin coating.

√For different requirements and applications, the following different coatings can be selected. For applications that need to improve abrasive wear performance, coatings containing C can be used, such as TiCN coating;

√For the application scenarios with high surface temperature, coatings with high Al can be used, such as alcrtin coating and AlTiN coating;

√The main purpose of plastic mold coating is to improve the surface hardness of the cavity, so as to minimize scratches and protect the polished surface from damage.
