How does Dongguan Metal Stamping Factory meet the basic requirements of stamping materials? [Hardware]

A master with 15 years of experience in Dongguan Hardware Stamping Factory has said that the selection of stamping parts is closely related to metal raw materials. Different plasticity, hardness, and composition of raw materials are directly related to the results of stamping parts. And how to choose raw materials that meet the results? Let me know with you: From the perspective of stamping parts processing, the mechanical properties, surface quality and thickness tolerance of stamping materials should meet the following basic requirements: The materials used for blanking should have sufficient plasticity and low Hardness to improve the quality and dimensional accuracy of the blanking section. Among them, soft materials (such as brass) have good punching performance, hard materials (such as stainless steel, high-carbon steel) have poor punching section quality, and brittle materials are prone to tearing during punching. The material used for bending should have sufficient plasticity, low yield strength, and high elastic modulus. Among them, materials with good plasticity are not easy to bend and crack, and materials with lower yield strength and higher elastic modulus have lower rebound. The material used for deep drawing should have better plasticity, lower yield strength and hardness, and larger plate thickness directivity coefficient. Among them, materials with high hardness are difficult to be deep-drawn; materials with a small yield ratio or a large directional coefficient of plate thickness are easy to be deep-drawn. When stamping, the deviation requirements of material thickness are relatively strict. This is because a certain die gap is suitable for stamping materials with a certain thickness. If the same die gap is used to stamp materials with large thickness differences, the quality and accuracy of the resulting workpiece will be reduced, and the die will also be easily damaged. Especially in the drawing, flanging and bending process, due to the uneven thickness of the material, it may lead to the production of waste. In the reshaping of large workpieces, the press can even be damaged. The mechanical properties of metal materials not only depend on their chemical composition, but also on their organizational structure. Generally speaking, the fine structure of the metal, the greater the plasticity, which is beneficial to the deformation of the material during stamping. However, if the structure of the metal is too fine, the strength and hardness of the material will increase. Hardware, 15 years of focusing on Dongguan hardware stamping factory, 5000 square meters production workshop, hundreds of precision processing production equipment, more than 20 R u0026 D design engineers. The monthly processing capacity of 100+ sets of molds, the daily production capacity of 3 million punching times, the stamping accuracy can reach 0.01mm, and the 16 quality inspections are strictly controlled. It can quickly solve the time-urgent problem of stamping parts, solve the problem of stamping accuracy, and solve the problem of production quality for you. Choose, choose rest assured!
