Metal flat washers, what are the reasons that affect the quality + 16 strict quality inspections

In the production and processing of metal flat washers, some poor-quality products are often scrapped. Increased costs, sluggish efficiency, and increased customer complaints. What are the general conditions that affect the quality? Xiaoshuo shares with you: 1. The quality of raw materials is inferior. 2. Due to improper adjustment of the previous process or wear of the rounded corners of the multi-process parts, the principle of equal volume during deformation is broken, and the size changes after punching are caused. 3. Due to poor positioning during operation, or poorly designed positioning mechanism, the blank moved during the blanking process. Or the inaccurate positioning caused by the defects of the shearing parts (prismatic degree, missing edges, etc.) can cause the size to be out of tolerance. 4. The blanking sequence is wrong. 5. The size of the die edge is out of tolerance. 6. The springback during the punching process of the metal flat washer, and the shape of the part in the previous process is inconsistent with the shape of the supporting surface of the working part of the mold in the next process, making the flat washer in the punching process Deformation occurs and elastic recovery occurs after punching, which affects dimensional accuracy. Hardware, 15 years of ingenuity and focus on metal flat washers, 20,000+ sets of mold customization production experience, monthly 100+ sets of mold processing capacity, 3 million punching times per day, stamping accuracy up to 0.01mm, and 16 quality inspections strictly. You can quickly solve the time-critical problem of precision stamping parts, solve the problem of stamping accuracy, and solve the problem of production quality. Choose, choose rest assured!
