How to improve the wear resistance of carbide molds

Time : 2024-03-14 Hits : 3

Carbide molds are widely used in industrial production. The higher the wear resistance, the longer their service life and the better they can cope with various harsh industrial production environments. So, what methods can effectively improve the wear resistance of cemented carbide molds?


After the carbide mold is vacuum coated, the surface can have an extremely low friction coefficient, thereby reducing processing stress. After the carbide mold is covered with vacuum coating, the surface hardness can be increased to 5 to 10 times, which can significantly reduce surface wear.


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. Coated cemented carbide molds have the following advantages:


Advantage 1: During the use of the mold, early failures often occur. Factors of failure are usually wear, corrosion, fusion, adhesion, etc. The consequence 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. Titanium plating surface treatment technology is a popular solution and 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, the service life of products that fail due to wear can be increased by more than 5-8 times after coating; the strain problem of products or molds caused by bite can be fundamentally solved after coating.


Advantage 2: The friction coefficient is reduced, which reduces the processing stress, thereby improving the surface hardness and greatly extending the life of the mold. It prevents products from being frayed and strained, improves product quality, and eliminates the trouble of unloading, polishing and reinstalling molds, thus improving the overall production efficiency.


Advantage 3: The microstructure of the TICN coating with fine nanoparticles has high toughness, high hardness, and high oxidation resistance, and can achieve an extremely smooth surface with no 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.


Advantage 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.
