Surface quality problems of stamping parts-hardware

There are many reasons for the surface quality problems of stamping parts. For example, the surface quality of coils, sheets, and molds will affect the quality of the final stamping parts. The operation during the stamping process and the clamping and removal of the station equipment may also be damaged. The surface quality of the parts, therefore, the details should be fully considered in each link of the entire manufacturing process, and try to avoid quality problems that 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. 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. Caused by the sliding of the roller; 7. Irregular damage to the edge; 8. The back of the material is pressed out of the bulge (the foreign body will disappear when it falls); 9. The traces of the roller (caused by the foreign matter attached to the roller); 10. The material outside the rules is poor; the above details accurately explain why the surface quality of the metal stamping parts is poor The problem. 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, in the above content, items 5, 8, and 9 are the most frequently occurring product defects or reasons. Need to know more about hardware stamping parts consultation:
