As we all know, the most effective and direct way to improve the wear resistance of cemented carbide molds is to use titanium plating to increase surface life, harden, add value, and improve wear resistance, corrosion resistance, etc.
After being coated with vacuum coating, the surface of the precision constant pressure mold can have an extremely low friction coefficient, reducing processing stress. The surface hardness of tungsten steel molds can be increased by 5 to 10 times after being coated with vacuum coating, which can significantly reduce surface wear. Especially when used for high-precision machining, very excellent surface quality can be obtained. Cold stamping and drawing molds can be coated with vacuum coatings to significantly reduce friction and significantly reduce scratches and wear during processing. Therefore, the service life can be increased and the cost can be greatly reduced. In addition, coating treatment has the following advantages:
1. The friction coefficient is reduced, reducing the processing stress. The surface hardness is increased, which greatly extends the life of the mold. It prevents the product from being frayed and strained, and improves the product quality. It saves the trouble of unloading, polishing and reinstalling the mold, and improves efficiency.
2. During the use of molds, early failures often occur. 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. To this end, the industry has successively introduced different solutions, and titanium plating surface treatment technology is a highly favored solution that can most effectively solve the above problems.PVD coating technology can be widely used in various types of tools, molds, mechanical parts, medical devices, etc. that may fail due to wear, bite, corrosion, adhesion, fusion, etc. Among them, products that fail due to wear (such as: blanking, cold heading, powder molding, etc.) can increase their service life by more than 5-8 times after coating; products or molds that suffer from strain due to bite (such as: extension dies, Stretching die, flanging die, etc.), it can be fundamentally solved after coating.
3. The microstructure of the TICN coating with fine nanometer particles has high toughness. It has high hardness, high oxidation resistance, and can achieve an extremely smooth surface without friction and chip removal, so that the excellence of the workpiece can be fully utilized. Compared with TIN coating, the surface finish is better, the friction coefficient is smaller, the hardness is higher, and the oxidation resistance is stronger.
4. For molds and parts, the coating process used for different molds (powder metallurgy molds, stamping molds, forming molds, drawing molds, forging molds and injection molds, etc.) and parts can significantly improve the surface hardness. , wear resistance, corrosion resistance, heat resistance and lubricity, etc.; and can facilitate film removal, greatly improving the quality (such as surface roughness, precision, etc.) and service life of molds and parts, making them effective product potential.
