On the classification of the properties of stamping dies

The total amount of stamping die production in China is in the forefront in the world, and it has gradually changed from the big country to the die exporting country. Our existing mold production more than 30 thousand enterprises, employing about 1 million people, 2012 sales of 124 billion yuan, production and sales, production, quality and level has been further improved, especially the development of the automobile industry and the IT industry, boosting the mold grades improved, provide a guarantee for excellent mold manufacturing equipment to enhance the level of mold technology the.



The accuracy of the multi position progressive die for some stamping dies and die making enterprises has reached 2 microns, and the life span can reach 300 million strokes. The multi station progressive die of individual enterprises has been used on the high speed punch press of 2500 times / minute, and the accuracy can reach 1 microns. It has been able to produce 43 inch large screen color TV, 65 inch rear projection TV moulded mold, 10 kilograms large capacity washing machine, a full set of plastic moulds, and automobile bumper, integral dashboard and other large plastic moulds.



Dalian stamping dies must withstand shock, vibration, friction, high pressure and tensile, bending and twisting loads. Even at higher temperatures, such as cold extrusion, the working conditions are complex, and it is easy to wear, fatigue, fracture and deformation. Therefore, the requirements for the working parts of the mold are higher than that of the ordinary parts.



Stamping is a pressure processing method that uses pressure on the press to make the material separate or plastic deformation at room temperature, so as to get the required parts. The materials for the stamping die are steel, hard alloy, steel cemented carbide, zinc based alloy, low melting point alloy, aluminum bronze, polymer material and so on.
