Practical methods for detecting precision stamping parts, hardware will talk about it for you

Practical methods for detecting precision stamping parts: 1. In the touch test of precision stamping parts, we recommend that you use clean gauze to wipe off the outer cover of the surface, and touch the gloves along the vertical stamping surface. Of course, this method requires certain experience. But this is a quick way. 2. The testing method of precision stamping parts is flexible yarn. It is mentioned here that the surface of the shell is wiped clean. Use soft sand to clean the entire surface of the longitudinal grinding of the towel surface. Punching, only pitting and indentation will be easy to find. 3. For the oil test of precision stamping parts, you need to wipe clean the surface except the cover with a clean gauze. Here you need to apply oil evenly along the direction with the cleaning brush to the entire surface of the stamping part, and then you can stamp it The parts are placed in a strong light summer test, where you can easily find whether there are tiny pits on the surface of the stamped corrugated cardboard. The above is about the detection methods of precision stamping parts. I hope it will be helpful to you. If you need to know more, please consult:
