The most effective and direct way to improve the wear resistance of tungsten steel molds is to plate titanium-to increase the surface life, harden, increase value, and improve wear resistance and corrosion resistance. The surface of the precision pressure-balanced mold covered by vacuum coating can have a very low coefficient of friction, reducing the processing force. 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 machining, it can obtain very excellent surface 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.
1. The friction coefficient is reduced, the processing force is reduced, the surface hardness is improved, and the life of the mold is greatly prolonged. It prevents the product from fraying and straining and improves the product quality. It saves the trouble of mold removal, polishing and reloading, and improves efficiency.
2. Moulds and parts, for different moulds (powder metallurgy moulds, stamping dies, forming dies, drawing dies, forging dies and injection moulds, etc.) and the coating process used for parts, the hardness of the surface can be significantly improved. Wear resistance, corrosion resistance, heat resistance and lubricity, etc., and can be easily removed, greatly improving the quality (such as surface roughness, accuracy, etc.) and service life of molds and parts, so that they can effectively play the product Potential.
3. In the process of mold use, early failure often occurs. The factors of failure are usually wear, corrosion, fusion, adhesion, etc. The problem is not only delaying the production cycle, but also greatly increasing production costs, thereby affecting the competitiveness of enterprises. For this reason, the industry has successively introduced different solutions, and the titanium-plated surface treatment technology is the most favored solution, which can most effectively solve 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, occlusion, corrosion, adhesion, and fusion. Among them, products that fail due to wear (such as: blanking, cold heading, powder molding, etc.) can increase their 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 fundamentally solved after coating.
4. The microstructure of the TICN coating of fine and nano-particles has high toughness, high hardness, high oxidation resistance, and can achieve an extremely smooth surface without friction and chip removal, so that the excellent properties of the workpiece can be fully displayed. TIN coating treatment has good surface finish, low friction coefficient, high hardness and strong oxidation resistance.
