Yong Wei steel mold (Dongguan) Co., Ltd. | S7 Rods | S7 is 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 where baler factory in Dongguan: Dongguan Yong Wei East's largest steel abrasive packaging equipment manufacturers in the development and production of packaging equipment in the forefront of the industry, has a professional R & D team and first-class production technology, several tens of thousands of domestic and foreign enterprises to provide goods packaging services. Use of packaging equipment, is a common way to produce paperback current business, in order to be able to compete in a leading position in the enterprise, many companies began using machinery to replace the traditional manual S7, which greatly promoted the product packaging efficiency, to bring tangible benefits to the enterprise. Vacuum heat treatment technology is developed in recent years a new type of heat treatment technology S7 manufacturers, it has the characteristics of S7 rod, mold manufacturing is urgently needed, such as to prevent oxidation and decarburization heating, vacuum degassing or outgassing, eliminating hydrogen embrittlement S7 wholesalers, thereby improving materials (parts) ductility, toughness and fatigue strength. Vacuum heating is slow, small temperature difference between inside and outside parts and other factors, determines the vacuum heat treatment process caused by deformation and small parts. Factor in the number of die steel chemical composition, grain size, purity, carbides and inclusions, morphology, size and distribution, as well as the microstructure after heat treatment systems such as tool steel and heat treatment of steel were obtained a great deal of impact toughness. In particular purity and thermal processing of steel deformation transverse impact toughness is more obvious. Toughness, strength and wear resistance are often conflicting. Therefore, a reasonable choice of the chemical composition of the steel and the use of reasonable refining, thermal processing and heat treatment processes to make the mold material wear resistance, strength and toughness to achieve the best fit.
