4 problems of sheet metal processing stamping parts
1. Burr: In the process of punching or trimming edges and corners, there is not completely leftover material. Burrs are generated under the section of the steel plate. When the burr height is 0.2mm or more based on the section of the steel plate, the iron powder generated will damage the mold and cause unevenness. .
2. Concave and convex: The surface of the material is abnormally convex or concave, which is caused by foreign matter (iron filings, dust) mixed in the uncoiling line.
