When the electroplating layer on the surface of the hinge is damaged, the air enters the interior, and the copper is oxidized, and the hinge will be damaged. Rusted. There are many reasons for the oxidation of copper, such as uneven plating on the surface of the hinge, cutting corners in the production process of the hinge, or the poor quality of the copper itself.
