What to do if there is rust on the surface of precision stamping parts

Netizens ask: After long-term use, the precision stamping parts have rust and there are a lot of stains on the surface. How should we deal with it? 　　Metal stamping manufacturer experts answered: Hello, this needs to consider the surface technology of precision stamping parts. If it is a powder sprayed part, it can basically be solved by the pickling process. If the rust is more serious, it will consume a lot of acid, and the time will be very long. The thickness of the metal after pickling will also increase. Quantitative control.　　 At the same time, I would like to remind you to pay attention to the usual care of precision stamping parts. If there is a cleaning and degreasing process, the easiest way is to apply oil to separate the metal and air/water. After processing, use vacuum packaging. And the temperature and humidity of the processing workshop must be controlled, especially the humidity. Metal will not rust without contact with air and moisture.
