Analysis of common defects in the production of stamping parts

When stamping parts are produced in stamping factories, stamping parts will have surface defects due to various reasons. Precision has been engaged in the custom processing of precision stamping parts for more than 10 years, and summarized some of the more common surface defects for your reference. 1. Adhesion, scratches: defects on the surface of the product or mold due to friction between the raw material and the mold base or cavity; 2. Burrs: the key is generated in the cutting die and the blanking die, and the gap between the knife edges is fluctuating. Burr; 3. Line deviation: When the product is formed, the part that first touches the mold is extruded and formed a line; 4. Concave and convex: the uncoiling line has dirt (iron filings, rubber, dust) infiltrated Concave and convex; 5, twists and turns: due to uneven stress, poor matching of stretch ribs or poor operation of the press slider, etc., tortuous and strain forces are generated at the r-corner or embossed parts of the product.
