Guangdong produces metal stamping parts, the basic requirements for stamping materials + raw materials use national standard original factories

The 15-year-experienced masters in Guangdong's metal stamping parts processing plant have 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, the material with good plasticity is not easy to bend and crack, and the material with lower yield strength and higher elastic modulus has 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 processing, the deviation requirements of the 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. The press can even be damaged during the reshaping of large workpieces. 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 material deformation 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 the production of metal stamping parts in Guangdong, 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 urgent problems of stamping parts, solve the stamping accuracy problems, and solve the production quality problems for you. Choose, choose to rest assured!
