Introduction of Defect Evaluation of Stamping Parts

In the production and processing, due to many uncertain factors, the obtained stamping products cannot be guaranteed to fully meet the quality requirements. In other words, some of the stamping products may have certain defects. One of the more common defects is cracking. For such problems, visual inspection methods are generally adopted. In the process of inspection, the evaluation of such defects in stamping products mainly includes: First, it is a type of defect, which can be noticed by users without training. Products with such defects cannot be tolerated by users. If it is discovered, it is necessary to freeze it immediately; the second type is a category B defect, which is a visible and predictable slender crack. Such shortcomings cannot be tolerated in areas I and II. Other areas of sewage treatment equipment can be repaired by welding, but must meet the repair specifications. Another common defect is strain, coarse grains, and dark damage. Visual inspection methods are usually used. Among them, Type A defects: strains, coarse grains, and concealed injuries that can be noticed by users without training. Stamping parts with such shortcomings cannot be tolerated by users and should be dealt with immediately after discovery; Type B shortcomings help to see It can be concluded that there are slender strains, coarse grains, and dark scratches. Products with such shortcomings can be tolerated in zone IV. The category C disadvantages mainly refer to the problems of slight strain, coarse grains, and dark scratches in the stamping products. Products with such shortcomings can be tolerated in Zone III and IV. In short, in the process of quality inspection of stamping products, different treatment measures need to be taken for its defects.
