Yong Wei steel mold (Dongguan) Co., SKD7 suppliers, SKD7 provided by Yong Wei steel mold (Dongguan) Limited. We are a steel mold, Dongguan City, An Yongwei shop (www.dgyongwei.com) located at: Dongguan specializes in: mold steel, DC53, SKD11.SUS440C, SUS420 for SKD7 rod for abrasives, machinery manufacturing sector has been its the largest market, accounting for 75% of total market abrasives applications. With the continuing recovery of world economic growth and motor vehicles, motorcycles and industrial production, to the field of transport equipment in 2013 is expected to be the most solid abrasives, the fastest growing market. Coupled with high-performance super-hard grinding wheel in the new field of energy, such as wind power equipment applications SKD7 supplier, abrasives demand growth in the machinery manufacturing abrasives will be much higher than the overall level of growth. Mold working life: the organizational structure of heat caused by unreasonable, excessive grain size, leading to major properties such as mold toughness, thermal fatigue performance, wear resistance and other fall SKD7, affect the working life of the mold. The manufacturing cost of the mold: a middle part of the mold cracking or final step of the manufacturing process, heat treatment caused the deformation tolerance and tolerance SKD7 material properties, in most cases will die scrap, can continue to use even by the repair, also increased working hours, extended delivery, increase manufacturing cost of the mold. It is the quality of heat treatment technology and mold have a very close relationship, making it two kinds of technology in the process of modernization, promote each other and improve together. Since the 1980s, the international mold heat treatment technology developed rapidly in the field of vacuum heat treatment technology, the mold surface strengthening technology and pre-hardened mold material technology.
