The discoloration of precision stamping parts has a certain relationship with the structural shape, the performance of the plating solution, and the running speed. In view of these factors, how can precision hardware solve the problem of discoloration of the coating?

For the structural shape, this is a physical phenomenon, and it is impossible for us to change the structural shape of the workpiece for electroplating. Due to the characteristics of the current, we cannot change the current distribution in different parts of the workpiece during the electroplating process. We can ignore this reason. Regarding the speed of the workpiece, this is a better solution. As long as we adjust the speed regulator of the extraction machine on the electroplating line to the appropriate speed. In this way, the thickness of the coating reaches the standard and is evenly distributed, and the coating is not easy to change color.

The performance of the plating solution is a key issue, and it is an important starting point for us to solve the discoloration of the workpiece. Therefore, when we choose the plating solution, we must test and compare repeatedly. Because the performance of the plating solution is transformed through a kind of open-type transformation, that is, the crystallization of metal ions on the precision metal stamping parts.

The crystal is fine and the gap between the crystal nucleus and the crystal nucleus is small, so the protective ability of the coating is strong, that is, the anti-corrosion and anti-oxidation ability is strong, and the coating is not easy to change color. On the contrary, if the crystal is rough, the gap between the crystal nucleus and the crystal nucleus is large, and its protective ability is poor, and the coating is easy to change color. In this way, when we choose a plating solution, we must choose a plating solution with fine crystals to electroplate the workpiece.
