Yong Wei steel mold (Dongguan) Co., W302 material, 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 1, high-strength cast iron bed, the internal stress relief import Bluff W302, so material stability, precision unchanged W302 material, the most suitable for continuous stamping production. 2, double guide column, a central pillar structure, using zero error to replace the traditional ball bearing slide structure, the dynamic friction to a minimum, with the forced lubrication to minimize thermal distortion and highest precision. 3, optional reverse side move to reduce vibration balancing device that Punch has the best accuracy and stability. 4, manual transfer mode, with high display mode and hydraulic locking device to facilitate transfer mode operation. 5, HMI microcomputer control, numerical, fault monitoring system, the screen display for easy operation. 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, etc. decline, affecting 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 performance in most cases will die scrap, even if the repair can still be used, an increase in time will , to extend the delivery W302, 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.
