Tungsten steel Die Mould coated with vacuum coating can increase the surface hardness by 5 to 10 times, which can greatly reduce the surface wear, especially when used for high-precision machining. Cold stamping forming and drawing die coating after vacuum coating can significantly reduce friction and significantly reduce scratches and wear during processing. In this way, the life of Tungsten steel Mould can also be increased and the cost can be greatly reduced.
The friction coefficient is reduced, the processing force is reduced, the surface hardness is increased, the life of the tungsten steel mould is greatly extended, and the product is prevented from being pulled and damaged, and the product quality is improved. The trouble of unloading the mold, polishing and reloading the mold is eliminated, and the efficiency is improved.
Tungsten steel moulds are extremely spare parts, and the coating process used for different molds (powder metallurgy mold, stamping mold, forming mold, drawing mold, forging mold, injection mold, etc.) and parts can significantly increase the surface hardness. Abrasion resistance, corrosion resistance, heat resistance and lubricity, etc., and can facilitate stripping, greatly enhance the quality of molds and parts (such as surface roughness, precision, etc.) and service life, making it effective to use products Potential.
In the use of tungsten steel moulds, early failures often occur. Nowadays, the industry has introduced different solutions in succession, and titanium-plated surface treatment technology is a favored solution that can solve the above problems most effectively. PVD coating technology can be widely used in various types of tools, molds, mechanical parts, and medical equipment that cause failures such as wear, bite, corrosion, adhesion, and fusion. Among them, products that fail due to wear (such as: blanking, cold heading, powder molding, etc.) can increase their lives by 5-8 times or more due to the abrasion of the product or mold caused by the bite (eg: tensile modulus, Drawing die, flanging die, etc.) can be fundamentally solved after coating.
The microscopic structure of the TICN coating on the fine nanoscale particles of tungsten steel moulds combines high toughness, high hardness, high oxidation resistance, and can achieve a very smooth surface without friction chip removal, so that the excellent quality of the workpiece can be fully utilized. Compared with the TIN coating, the surface finish is good, the friction coefficient is small, the hardness is high, and the oxidation resistance is strong.
