How to control the appearance of poor precision stamping parts
For the production of precision stamping parts, if the steel raw materials are imported stainless steel materials, the precision hardware parts that are punched out often have appearance defects such as spots, crushes, and scratches. At the same time, when this happens, add a vacuum cleaner and exhalation nozzle to the punch, but the effect is not ideal. In fact, there are many ways to deal with this situation:
1. Add a protective film and stick it on the material. Ask the supplier when buying the material. Do not add oil or water when the product is processed. Let the product be discharged one by one during production. The cutting knife is overlapped and easily crushed or bruised! The cost is higher and can be considered.
2. If it is not possible, try using different raw materials. The performance of imported SUS and domestically produced products are sometimes quite different. The performance of different suppliers is also different, but while ensuring sufficient performance, controlling the cost is also a way to solve the problem!

3. Add appropriate amount of punching oil, (to lubricate the punch and cut the mouth to prevent the generation of waste) cleaning the mold regularly, sharpening the punch in time, keeping the sharpness, and reducing the generation of debris is also an effective method!
4. The finish of the mold must be good. The surface of the mold should be cleaned with a brush during processing. The surface of the mold and the workbench should be cleaned frequently. There should be no iron filings and other particulate impurities on the surface of the material or mold, but the production efficiency is reduced. In terms of scrap rate, it is acceptable!
