Said ordinary abrasive abrasive characteristics of the project are: the shape, size abrasive, grain size, hardness, organizations and bonded abrasives abrasive hardness refers to the external force, from the degree of difficulty shedding abrasive surface, which reflects the strength of the bond holding the abrasive grains hardness depends primarily on the amount of binding agent to the number and density of abrasive grit off easily, said low abrasive hardness; contrary, indicates a high level of hardness hardness general points. ultra-soft, soft, soft, medium, medium hard, hard and superhard seven level SKD11 clinker from these levels can be subdivided in a number of small magnitude. abrasive hardness measurement method, more commonly used hand cone, mechanical cone method, Rockwell hardness measurement method and blasting hardness assay. Mold manufacturing is the basis for the entire industrial manufacturing technology and equipment, electronics, automotive, electrical, electronics, instrumentation, home appliances and telecommunications products, 80% to 90% of the parts have to rely on forming mold, die determines the shape of these products Overall SKD11 suppliers, processing quality and precision mold will determine the quality of these products. The future of China's mold industry after restructuring Dongguan SKD11, precision molds will be increasingly high SKD11, mold steels are increasingly high requirements. Ding metal crown according to national and international development of mold market, the introduction of Sweden Assab quality tool steel, especially high-quality ASP-23 high-speed steel powder wholesale, ASP-60 high-speed steel powder wholesale, ASP-23, ASP-60 CPM quality even without segregation, wear resistance, high toughness, mold making to meet the requirements of life.
