What are the requirements for stamping materials for stamping parts?

When selecting the information of stamping parts, not only should the application function be considered, but also the stamping processing and subsequent process function requirements should be satisfied. 1. The stamping parts have a good stamping and forming function. For the forming process, such as stretching, bending, segmentation, convex hull, etc., the material should have a good stamping and forming function, that is, it should have good crack resistance and good die attach. The product is easy to be deformed and broken, which will cause difficulty in repairing the mold. For separate processes, there is a certain degree of plasticity in the requested data. 2. The stamping parts have a higher nominal quality. The material name should be smooth and flat, without defects and damage. The material with good nominal quality is not easy to break during molding, and it is not easy to scratch the mold, and the nominal quality of the part is also good. 3. The thickness tolerance of stamping materials should meet national standards. Because certain mold gaps are only used for materials in a certain thickness range, if the thickness tolerance of the data is too large, it will not only directly affect the quality of the parts, but may also lead to the appearance of the finished product. In the process of calibrating tortuosity, shaping, etc., it is possible that the mold or the press may be damaged due to the excessive thickness deviation.
