The most effective and direct way to improve the wear resistance of tungsten steel moulds is titanium plating – to increase the life of the surface, harden, add value and improve wear and corrosion resistance.
Advantage 1: Reduced coefficient of friction, reducing the processing force Improve the surface hardness, greatly extending the life of the mould Prevent the product from pulling hair, pulling, improve product quality Save the trouble of unloading, polishing and then loading the mould, improve efficiency.
Advantage 2: In the use of moulds, early failure often occurs. Failure is usually caused by wear, corrosion, fusion, adhesion, etc. The problem is not only the delay of production cycle time. The problem is not only to delay the production cycle, but also greatly increase production costs, which in turn affects the competitiveness of enterprises. PVD coating technology can be widely used on tools, moulds, machine parts, medical devices, etc., which fail due to wear, galling, corrosion, adhesion, fusion, etc. Among them, the products failing due to abrasion (e.g. punching, cold heading, powder moulding, etc.) can be coated to increase their life span by 5-8 times; and the problems of straining of products or moulds caused by occlusion (e.g. drawing mould, stretching mould, flanging mould, etc.) can be solved fundamentally after coating.
Advantage 3: The microstructure of the TICN coating with fine nanoparticles combines high toughness, high hardness, high oxidation resistance and a smooth surface for frictionless chip removal. High hardness, high oxidation resistance and extremely smooth surface with frictionless chip removal can be realised, so that the excellent properties of the workpiece can be fully developed. Compared with the TIN coating, the surface finish is good, the coefficient of friction is small, the hardness is high, and the oxidation resistance is strong.
Advantage 4: Moulds and parts, for different moulds (powder metallurgy moulds, stamping moulds, forming moulds, drawing moulds, forging moulds and injection moulds, etc.) and parts of the coating process, can significantly improve the surface hardness, abrasion resistance, corrosion resistance, heat resistance and its lubrication, etc.; and can be conveniently removed from the film, and vigorously enhance the quality of the moulds and parts (such as surface roughness, precision, etc.) and service life, so that it can effectively play a product potential. Effectively bring out the potential of the product.
