The stamping material of precision stamping parts should meet the corresponding process requirements, for example, its thickness tolerance should comply with national standards. Although different die gaps are suitable for materials of different thicknesses, if the thickness tolerance of the material is too large, it will not only directly affect the quality of precision stamping parts, but also may cause damage to the die or press.
At the same time, the materials required to produce precision stamping parts have higher elongation and cross-sectional reduction, lower yield and higher tensile strength, higher plasticity, and greater deformation, which is beneficial to the stamping process. Stability and uniformity of deformation improve the precision of forming dimensions of precision stamping parts.
In addition, stamping materials must have good adaptability to mechanical joining and continued processing to reduce the possibility of damage to mechanical equipment. Using materials that can meet all the above conditions to make precision stamping parts, the quality is absolutely guaranteed. Moreover, the material itself must have a high surface quality, and there must be no defects such as oxide scale, cracks, rust spots, scratches, delamination, etc., and high-quality materials are not easy to break during processing, and they are not easy to scratch the mold. The obtained precision stamping parts The surface quality is also good.
