Yong Wei steel mold (Dongguan) Co., A2 material, A2 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 workpiece machining accuracy and finish higher, when the need to use fine-grained grinding with, because the finer A2, abrasive cutting, the more the residual number, the smaller the traces of the abrasive cutting, the surface roughness is smaller. Reasonable choice of abrasive hardness, is the key to a good grinding effect. The most basic principle is to ensure that in the process of grinding the mill with the appropriate self-sharpening to avoid abrasive wear too much or burn the workpiece. Select soft abrasive grit generated during off razor, causing unnecessary wear A2 material, which can cause unnecessary wear. Mold steel is used to make Die, mold and other mold forging die steels. Mold material is the material and technical basis mold manufacturing industry, which is the traditional mold mold steel material, its variety, size, quality performance for mold manufacturing cycle life and plays a decisive role. In recent years, mold steel production at home and abroad, production techniques, technology and equipment, quality, variety, etc. have achieved relatively rapid development, China has emerged Fushun Special Steel, Changcheng Special Steel A2 rod, Xingcheng Special Steel, Hangzhou and a number of high-quality steel production enterprises, the development of mold steel industrial products also contributed to the development of the high-class, individualized, high value-added direction. Mold very versatile and manufacture of molds with a wide range of materials, in the mold material was undoubtedly the most widely used steel mold.
