Liuzhou powder high speed steel, Yong Wei mold steel, V4-speed steel powder 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! 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, 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 powder high speed steel, 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 Vickers organizations and other non-normal tissue DEX40 powder high speed steel, 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. Over the years, the domestic steel mills in order to increasingly competitive market remained tenacious ability to survive V4 powder high speed steel, but also moves Qi out, the author interviewed for this mill is through a university Institute launched a cooperative, mutually take the long, interlibrary loan resources, 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. After the completion of a production cycle, to work on the mold surface, sports, professional guide member coated anti-rust oil, in particular should pay attention to the strength of the stretch with a gear rack mold mold bearing parts and springs of protection to ensure that it remains in top working condition; as production lasts, cooling channels easily deposited scale, rust, mud and algae, so that the cooling channel cross-section smaller DEX20 powder high speed steel, cooling channel narrows significantly reduced between the coolant and the mold heat exchange rate, increased production costs. Dongguan mold steel processing enterprises should first give each deputy dies with history cards, detailed records, statistics of its use, care (lubrication, cleaning, rust) and damage, which can be found whereby parts, components have been damaged, worn extent size, to provide discovery and problem-solving information, and the mold molding process parameters, materials used in the product, in order to shorten the mold test time and increase productivity. Die stress state at work are complex, such as hot work die is usually subjected to alternating stress at alternating temperature field, so it should have good prevent mold into a soft or plastic state capacity, and In the long-term working shape of the mold remains unchanged, and the dimensional accuracy. Generally finished mold hardness, cold mold often choose, hot die often choose around. It also determines the macroscopic surface copper consumption growth will be affected. Electricity use copper as the largest copper field, the first nine months, the cumulative increase of grid investment is only 3.55 percent, 11.41 percent decline in total investment in the power supply. We learned from the research point of view, grid investment growth is less than expected, mainly because: on the one hand, slowdown in economic growth leads to social decline in consumption growth, after the addition of UHV power grid investment, mainly for distribution expansion and transformation of the grid, in the case of electricity consumption growth rate of decline, the number of expansion and renovation project is no longer urgent, resulting in a number of projects in spite of successful enterprises, but did not issue orders.
