Problems that are prone to occur during the stamping process of parts

Common problems that may occur during the manufacturing process:

1. Adhesive and scratch marks: defects that occur on the surface of parts or molds due to friction between materials and convex or concave molds;

2. Burr: mainly occurs in the gap between the cutting die and the cutting die, and burrs are produced when the gap between the cutting edges is large or small;

3. Line offset: When the part is formed, the part that first contacts the mold is squeezed and forms a line;

4. Convex concave: foreign objects (iron filings, rubber, dust) mixed into the unwinding line causing convex concave;

5. Turmoil: Due to uneven stress, poor matching of stretching ribs, or poor control of the press slide, the corners or embossed areas of the workpiece may experience twisting and strain;

6. Wrinkles: Wrinkles on the edges or r area are caused by poor adjustment of the press slider, low press accuracy, inappropriate adjustment of air cushion pressure, large punch or r area, and other reasons.
