As the core of the stamping die work, the punch is to make the material separation or plastic deformation, so as to obtain the necessary parts, stamping die supporting operations play an important role.
　　Punch is installed in the stamping die for continuous punching punching thrust operations, the processed material separation or plastic deformation, in order to obtain the required finished or semi-finished products. Stamping die in the cold stamping process, the material processed into parts. Stamping is a method of 　　pressure processing at room temperature where pressure is applied to a material by means of a mold mounted on a press to produce a separate or plastic deformation to obtain the desired part, which is common in industrial production. Stamping die is indispensable for the production of stamping equipment, is a technology-intensive products. Stamping parts of the quality, production efficiency and production costs, and mold design and mold parts of the precision quality has a direct relationship.
　　1, tungsten steel punch round bar processing Compared with the metal,
　　MC nylon low hardness, no damage to the grinding pieces;
　　2, low m c coefficient, providing its widely used in friction parts may be;
　　3, high chemical stability, alkali, alcohol, ether, hydrocarbons, weak acid, lubricants, detergents, water (sea water), and has odorless, non-toxic, tasteless, no rust characteristics, for its wide application In the anti-alkali corrosion, environmental health, food, textile printing and dyeing and other aspects of the use of mechanical parts to provide excellent conditions.
　　4, to simplify the maintenance of the machine, save labor, excellent mechanical cutting performance, improve labor productivity;
　　5, tungsten steel punching production and processing of high strength, able to bear the load for a long time;
