Why is the surface quality of metal stamping parts poor?-

Why is the surface quality of metal stamping parts poor? There are many reasons for the surface quality of metal stamping parts. For example, the surface quality of coils, sheets, and molds will affect the quality of the final stamping parts, the operations during the stamping process, and the station equipment. The clamping, removal, etc. may also damage the surface quality of the parts. Therefore, in each link of the entire metal stamping parts manufacturing process, details should be fully considered to avoid quality problems and affect the final product appearance. 1. Common undesirable phenomena of coil materials mainly include the following aspects: 1. There are foreign objects on the surface or inside of the steel plate; 2. The foreign objects are peeling off, and the coil is in a scar-like state; the coil is bad 3. The corners of the coil are damaged; 4. Edges The angle (20-30mm) is deformed or wrinkled due to uneven stress; 5. Scratches (caused by the surface of the roller or foreign substances); 6. After the foreign body enters, the bulge is pressed out on the back of the roll (the foreign body disappears when it falls); 7. Roll traces (caused by foreign matter attached to the roller); 8. Poor material beyond the rules The above details all explain why the surface quality of the metal stamping parts is poor. In addition, there are obvious groove marks on the surface depth caused by foreign matter, which is also the main reason for the poor surface quality of metal stamping parts. According to practical experience, it is found that the frequency of defects caused by foreign bodies is the highest among the above content.
