Shapingba tungsten steel | Japan VA35 Tungsten | AsiaVest steel mold (certified merchants) provided by the Dongguan City An Yongwei steel mold shop. Dongguan City An Yongwei mold steel shop (www.dgyongwei.com) is a professional "mold steel, DC53, SKD11.SUS440C, SUS420" of the company. Since its inception, we adhere to the "honesty, sound management" approach, the courage to healthy competition in the market, so that "Sweden Assab, Daido, Hitachi, Austria Bluff" brand has a good reputation. We adhere to the "service first, customers first" principle, the permanent mold steel Granville won the trust of customers congregation in special steel, and establish a good corporate image. Special Note: This information is for reference pictures and information, please contact us to obtain the most accurate information, thank you! Shoddy steel material containing impurities, the density of steel is small, but size tolerance serious, so in case there is no vernier caliper, check that it can be weighed. For example, for steel 20, the national standards set forth in the most negative tolerance of 5%, length 9M single theory when it weighs 120 kg, and its minimum weight should be: 120X (L-5%) = 114 kg, Weigh out the actual weight of 114 kg single smaller than it is shoddy steel, because it exceeded the 5% negative tolerance. PVD is divided into a vacuum deposition, sputtering and ion plating. Ion plating is a combination of vapor deposition and sputtering techniques, ion plating has a strong adhesion force, are good throwing power, the base material to be plated and plating materials can be widely with other advantages, to thereby obtain a wider range of applications. In recent years, multi-arc ion plating people's attention. At present, more in the mold used is ion plating TiN, this film is not only high hardness and good toughness film, combined with strong, high temperature. Multiple TiN film developed on the basis of such (TiAl) N, (TiCr) N, the performance is better than TiN, is a kind of new film is more promising. Binder components such as pressure plate, excellent strength glue, etc., unloading parts such as the stripper plate, pneumatic roof materials. Check all parts of the relationship and when maintenance parts for damage, repair the damaged part, pneumatic ejector check for air leaks tungsten steel, and to take measures to the specific situation. Such as the trachea replace damaged. Share Boro mold steel springs and other parts in the course of an elastic spring most easily damaged, usually a fracture and deformation phenomena. The approach taken is to replace, in the replacement process must pay attention to the spring specifications and models, specifications and models spring confirmed by color, diameter and length of the three, and only three are in the same situation before they can be replaced. Imported steel mold normalizing in different steel can have different purposes. Such as low carbon steel, mainly in order to increase the hardness and improve the processing performance, prevent cutting a "sticky knife" is like. For carbon steel, low alloy steel, has refined the organization, homogeneous, uniform performance and reduce the hardness and so on. High carbon steel, alloy steel mesh to eliminate carbide, ready to organize uniformity further heat treatment. For carburizing steel, can also eliminate the carburizing layer mesh carbide and improve performance. For castings, forgings also eliminate abnormal tissue Vickers organizations, grain refinement. Stage exports of steel leg, although relatively small, but also for the development of diversified steel provides a variety of profit point. At present, the domestic mills eyes stare but it is still mainly in the domestic top. For a long time, steel mills in order to maintain the viability of tenacious increasingly fierce competition in the domestic market, but also moves Qi out, the author interviewed for this mill is through the Institute launched a collaboration with a university in Japan's imports FD15 tungsten steel, each getting Director of tungsten steel RD20, interlibrary loan resource tungsten steel VA50, forming a virtuous circle of very good, geopolitical advantages, resources used to make the best out of high-efficiency mode 1 + 1> 2. So this is the steel products market share in competitive big an important factor.
