The main material for making metal stamping dies

Metal stamping parts have been widely used in many fields such as electronics, electrical appliances, auto parts, home decoration, etc. in the world today; metal stamping parts are mainly cold stamped, in fact, all kinds of metal materials are used in different levels through corresponding molds. The punch press performs cutting, stretching, bending, forming, finishing and other processes to achieve the shape designed by the project. Metal stamping is a process that uses punches and molds to deform or break iron, aluminum, copper and other plates and other materials to achieve a certain shape and size. Metal stamping is sometimes called sheet forming, but there is a slight difference. The so-called sheet forming refers to the use of sheet materials, thin-walled tubes, thin profiles, etc. as raw materials. The forming method of plastic working is collectively called sheet forming. At this time, the deformation in the direction of the thick plate is generally not considered.　The main material of Dongguan hardware stamping die is die steel (including tool steel and high-speed steel), and sometimes hard alloy stamping die is usually required to have high hardness and wear resistance, heat treatment is essential. It is to impact a sphere of specified mass on the surface of the sample at a specified speed, and test the difference between its initial speed and the rebound speed to determine the hardness value of the sample. To understand this, just look at how thick the standard hardness block of the Leeb hardness tester is. Obviously, the measured hardness value is neither the hardness of the nitride layer nor the hardness of the base material, but the result of the interaction of the two. Because the thickness of the surface layer of the stamping part is different, different results will inevitably be obtained. Previous post: Production material requirements, metal stamping parts
