What are the material requirements for precision stamping? 'Hardware'

Precision stamping processing has the following requirements for materials: 1. The material used for punching should have sufficient plasticity and low hardness to improve the quality of the punching section and dimensional accuracy. 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. 2. 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. 3. 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. 4. The surface of the material should be smooth and clean, without scratches, scratches and other defects, so as not to affect the appearance quality of the product, and facilitate stamping processing, welding, spraying and other subsequent processing. 5. The thickness tolerance of the material should meet certain requirements: if the material thickness is out of tolerance, it will not only directly affect the stamping quality of the product and the life of the mold, but may also produce waste or damage the mold.
