Actually, there are many reasons for the rust of the hinge. The surface treatment is not in place, and the scratches and bumps after spraying will cause rust. The main cause of electroplating rust is the process problem in electroplating production, which is the key to maintaining the corrosion resistance of the hinge.
The protection of the electroplating layer after electroplating to avoid bumps and scratches. After electroplating, bumps and scratches can easily scratch the electroplated layer, thereby exposing the iron inside, so that the air humidity is high. It is easy to oxidize and rust.
