Yong Wei steel mold (Dongguan) Co., W302 rod, W302 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 Meanwhile W302, Bonded Abrasives will follow W302 Suppliers, rapid growth of the world, mainly due to abrasive further expansion and the sudden emergence of super-hard materials and products in China and other emerging market economies. The coated abrasives because of its growing technological innovation, it has the largest number of products in abrasives categories, but also because of the unique advantages of coated abrasives in the grinding process chain late, greatly promoted the coated Application of abrasive polishing. 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 W302 rod, the impact of 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 properties imported Bluff W302, discarded in most cases will die, can continue to use even by the repair, will increase working hours, to extend the delivery time, improve the 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.
