The Main Solution To The Discoloration Of The Plating Layer Of The Hardware Terminal

The main solution to the discoloration of the plating layer of the hardware terminal.
The method to solve the discoloration of the plating layer in the production process of the hardware stamping terminal is related to its structural shape, the performance of the plating solution, and the speed.
1. As far as the structural shape of the hardware terminal is concerned, this is a physical phenomenon, so we cannot change the structural shape for electroplating.
Of course, we cannot change the distribution of current in different parts of the hardware terminal during the electroplating process, because this is the characteristic of the current. These are actual problems that cannot be resisted by humans.
2. The speed of the hardware terminal is an important issue, but it is an easy problem to solve. As long as we adjust the speed frequency converter of the electroplating line to the appropriate speed, the plating layer of the hardware terminal will not easily change color.
3. The quality of the plating solution performance is a key issue and an important starting point for us to solve the terminal discoloration phenomenon. Therefore, when we choose the plating solution, we must repeatedly test and compare. Because the performance of the plating solution is transformed through a release formula, that is the crystallization of metal ions on the hardware terminal.
If the crystal is fine, the gap between the crystal nuclei is small, and the coating has strong protection ability, that is, strong corrosion and oxidation resistance, and the coating is not easy to change color. On the contrary, if the crystal is rough, the gap between the crystal nuclei is large, the protection ability is poor, and the coating is easy to change color. Therefore, when we choose the plating solution, we should choose the plating solution with fine crystals for electroplating hardware terminals.
