Some ies, such as natural diamond dies, polycrystalond dies (PCD dies), tungston carbide dies, beside, and imported American GE dies. They may draw some soften harder ones as well. Eg. The soften copper inum e harder g iron s steel ng PMJ natural diamond dies have very high smooth finish, precise dimensions and good wear resistance, which can be used in the process of drawing various ferrous and non-ferrous metal diameters of die hole: 0.02 ~ 1.50mm. We can manufacture the dies of tiny stainless steel e dies are sold to worldwide well.JPMJ polycrystalond dies (PCD dies) have very good smooth finish, precise dimensions and very high wear resistance (its use limit even several times longer than natural diamond die), which can be used in the process of drawing various ferrous and non-ferrous metal We use the PCD die blanks from COMPAX GE (United States) or SUMIDIA SUMITOMO (Japan) or CD (China) & ordinary PCD (China).The core of JPMJ tungsten carbide die is sintered by the highest grade of virgin tungsten powder, and the casing meet the requirement of perfect roundness and concentricity. JPMJ tungsten carbide dies can be used in the process of drawing various ferrous and non-ferrous metal With 15 years experience in service the with all the major industrial specifications. All our dies are 100% completely guaranteed for the materials and fabrication.
