Hardware tells you how to solve the poor appearance of precision stamping parts

In the production of precision stamping parts, sometimes appearance defects such as spots, crushes, and scratches often appear. At the same time, when this happens, add a vacuum cleaner and exhalation nozzle to the punch, but the effect is not very satisfactory. In fact, to deal with the poor appearance of precision stamping parts, there are many ways to solve it: 1. Precise stamping parts are covered with a protective film and attached to the material. When buying materials, the supplier is required. No oil or water is added during product processing. During production, the products are delivered one by one, and the blanking knife is overlapped and it is easy to be crushed and bruised! The cost is higher and can be considered. 2. The precision stamping parts are really not good. You can try different raw materials. The performance of imported SUS and domestically produced products is sometimes very different. The performance of different suppliers in our country is also different, but while ensuring sufficient performance, cost control is also a way to solve the problem! 3. Add an appropriate amount of punching and shearing oil to the precision stamping parts (to lubricate the punch and cut the mouth to prevent (Waste generation) cleaning the mold regularly, sharpening the punch in time, keeping sharp, and reducing the generation of debris is also an effective method! 4. The mold must have a good finish. Use a brush to clean the surface of the mold during processing. Clean the surface of the mold frequently. And the workbench, there should be no iron filings and other particulate impurities on the surface of the material or mold, but the production efficiency is reduced, and the rejection rate caused by the poor appearance of the precision stamping parts is still acceptable.
