The advantages of drawing die steel
1: reduced the coefficient of friction, reducing machining force to improve the surface hardness, greatly prolongs the service life of the mould to prevent galling, injury, improve the quality of the products, then loaded and unloaded without polishing die troubles, improve efficiency
The use of 2: in the process of mould, the early failure often occurs. The failure factor is usually wear, corrosion, adhesion, fusion etc.. The problem is not only delay the production cycle, but also greatly increased the cost of production, thereby affecting the competitiveness of enterprises. To this end, the industry launched different solutions, and titanium surface treatment technology is favored by the scheme, can effectively solve the problem. PVD coating technology can be widely used in various types of wear, corrosion, adhesion, occlusion, etc. caused by the failure of the fusion tool, mould, mechanical parts, medical equipment etc.. Among them, because of wear caused by failure of the products (such as: blanking, cold forging, powder molding etc.) after coating can improve the service life of 5-8 times; damage caused by occlusion or mold products (such as: drawing die, drawing die, flanging die, etc.) after coating can be solved fundamentally.
Tungsten steel drawing die mold quality include the following:
1: the stability of product quality, product size compliance, product surface finish products, material utilization and so on;
2 life: in the premise to ensure the quality of products, the number of working cycles or the production of mold parts can be completed;
3 repair costs, repair cycle and so on.
The basic way to improve the quality of tungsten steel mold:
The 4 parts of the design to be reasonable, the structure of the best possible process, and the feasibility of product designer should consider the technical requirements of parts and structure must mold manufacturing.
