In fact, there are many reasons for the rust of the hinge. The surface treatment is not in place. Scratches and bumps after spraying will produce rust. The cause of electroplating rust is mainly the processing problem in electroplating production, and the key to maintain the corrosion resistance of hinges.

The protection of the electroplated layer after electroplating is to avoid scratches and scratches. After electroplating, the scratched pair can easily break the electroplated layer, thereby exposing the iron inside, so that the air humidity is large, it is easy to oxidize and rust.
