The most effective and direct way to improve the wear resistance of tungsten carbide die is titanium plating-surface life enhancement, hardening, value-added and improving wear resistance and corrosion resistance.
The surface of the precision pressure-balanced die after being coated with vacuum coating can have a very low friction coefficient, 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.
Advantage 1: Reduce the friction coefficient, reduce the processing force, increase the surface hardness, greatly extend the life of the mold, prevent the product from fraying and strain, and improve the product quality. Eliminate the trouble of mold removal, polishing and reloading, and improve efficiency
Advantage 2: 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.
Advantage 3: The microstructure of the TICN coating of fine 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. Compared with TIN coating treatment, the surface finish is better, the friction coefficient is small, the hardness is high, and the oxidation resistance is strong.
Advantage 4: Molds and parts, for different molds (powder metallurgy molds, stamping molds, forming molds, drawing dies, forging dies and injection molds, etc.) and the coating process used in the parts, the surface hardness can be significantly improved , Wear resistance, corrosion resistance, heat resistance and lubricity, etc.; and can facilitate the release of the film, greatly improve the quality (such as surface roughness, accuracy, etc.) and service life of the mold and parts, so that it can be effectively used Product potential
