After being covered by vacuum coating, the fine wire drawing dies can have a very low friction coefficient and reduce processing stress. The surface hardness of the tungsten steel mold can be increased by 5 to 10 times after being covered by the vacuum coating, which can greatly reduce the surface wear, especially when used for high-precision processing, it can obtain very good appearance quality. After the cold forming and drawing molds are covered by vacuum coating, the friction can be significantly reduced, and the scratches and wear during processing can be significantly reduced. Therefore, the life span can be increased and the cost can be greatly reduced.

         Advantage 1: The microstructure of the TICN coating of fine nano-particles has high toughness, high hardness, high oxidation resistance, and can complete a frictionless chip removal with an extremely lubricating appearance, so that the excellent performance of the workpiece can be fully displayed. Compared with TIN coating treatment, the surface brightness is better, the friction coefficient is small, the hardness is high, and the oxidation resistance is strong.

        Advantage 2: In the process of using wire drawing dies, early failures often appear. The factors of failure are usually wear, corrosion, fusion, adhesion, etc. The problem is not only to delay the consumption cycle, but also to greatly increase consumption costs, which in turn affects the competitiveness of enterprises. To this end, the industry has successively introduced different treatment plans, and the titanium-plated surface treatment technology is a favorite plan that can most effectively deal with the above-mentioned problems. PVD coating technology can be widely used in all kinds of tools, molds, mechanical parts, medical devices, etc. that cause failure due to wear, seizure, corrosion, adhesion, and fusion. Among them, failure products caused by wear (such as: blanking, cold heading, powder molding, etc.) can increase life by more than 5-8 times after coating; product or mold strain problems caused by seizure (such as: drawing die, Stretching dies, flanging dies, etc.), can be basically processed after coating.
