Metal stamping parts manufacturer, material selection of automobile stamping parts + 16 quality inspection manufacturers

Manufacturers of metal stamping parts have different product usage scenarios for different customers, and the metal materials they need to choose will also be different. Xiaoshuo sorts out a few points and shares with you the characteristics of some metal materials that the car acts on: 1. The blanking requires that the plate should have enough plasticity to ensure that the plate does not crack during the blanking. Soft materials have good punching performance. After punching, parts with smooth cross-section and small inclination can be obtained; hard materials have poor quality after punching and have large cross-sectional unevenness, which is especially serious for thick plates. For brittle materials, tearing is easy to occur after punching, especially when the width is small. 2. The plate that needs to be bent and formed should have sufficient plasticity and a lower yield limit. Sheets with high plasticity are not easy to crack when bent. Sheets with lower yield limit and lower modulus of elasticity have small rebound deformation after bending, and it is easy to obtain a curved shape with accurate dimensions. Materials with greater brittleness must have a larger relative bending radius when bending, otherwise cracks are likely to occur during the bending process. 3. Sheet drawing, especially deep drawing, is one of the more difficult stamping processes. Not only the drawing depth is required to be as small as possible, the shape is as simple as possible, and the transition is smooth, but also the material has better plasticity. Otherwise, it is very easy to cause the parts to be distorted and deformed as a whole, partially wrinkled, and even stretched to crack.
