Common Defects in Stainless Steel Stamping Parts:
1. Cracks: Due to the high hardness and toughness of stainless steel, cracks will occur when the deformation exceeds the material's tolerance limit during the stamping process. For example, during stretching, if the elongation coefficient is too small, excessive local deformation of the material can easily lead to cracks at the edges or rounded corners of the part.
2. Wrinkling: This usually occurs during the stretching process. When the blank holder force is insufficient to effectively suppress material flow, the material will become unstable and form wrinkles. Wrinkling is especially common with thinner stainless steel sheets.
3. Scratches: An uneven die surface, impurities, or relative sliding between the part and the die during stamping can leave scratches on the surface of the stamped part, affecting its appearance and quality.
4. Dimensional Deviations: Insufficient die manufacturing precision, decreased precision of the stamping equipment, and fluctuations in material properties can all cause the dimensions of the stamped part to fail to meet design requirements. 5. Burrs During the stamping process, wear of the die cutting edge, excessive or insufficient clearance will cause burrs on the edge of the stamped part, which not only affects the appearance, but may also affect subsequent processing and use.
