No matter how experienced the stamping processing factory is, it is inevitable that defective products will be produced during the production process, and the most common is that the surface of the stamped parts presents a concave convex shape. And this phenomenon is unacceptable to customers for some exterior parts.

However, the main reason for the occurrence of concave convex problems is due to the adhesion of dust or some iron filings on the surface of the material or stamping die. Let's explain in detail the specific main reasons: 1. Iron powder is generated when the coil material is cut off; After cutting the coil material, there are burrs left on the cutting surface, and the stamping processing plant may attach dirt and stains during the storage or handling of the sheet metal;

2. Stamping die: Iron powder is generated when the stretching rib is burned, the protrusion and depression of the stamping part are caused by the unreasonable position of the limit exhaust hole of the stretching die, and the protrusion and depression are caused by the shearing die;

3. Improper speed setting of the robotic arm leads to collisions and other adverse effects when entering the stamping mold, resulting in defective stamping parts.

Based on the above points, stamping factories can minimize the production of defective products with concave convex problems during the production process.
