Rectifier is the core equipment in electroplating process, which is used to convert alternating current (AC) into controllable direct current (DC) and provide stable current and voltage output. Its role directly affects the plating quality, uniformity and productivity. The following are the key roles and technical details of rectifiers in plating: 

 

 

1. Power supply conversion 


Converts AC power to DC power required for plating, providing stable unidirectional current drive for metal ion deposition.

 

2. Precise control of process parameters 


Control the thickness, uniformity and adhesion of plating layer by adjusting current strength and voltage to meet different material and plating layer requirements. For example, SCR rectifiers can be adjusted with high precision to adapt to complex process requirements.

 

3. Guarantee stability and reliability 


provides fluctuation-free DC output to ensure dense and uniform plating layers, and is equipped with over-current and over-voltage protection functions to minimize the risk of production interruption.

 

4. Realize energy saving and consumption reduction 


Adopts advanced technologies such as high-frequency switching or SCR to improve the efficiency of power conversion and reduce the energy cost of mass production.

 

5. Intelligent management 


Integrates remote monitoring, automatic adjustment and data collection functions to optimize plating parameters in real time and improve production efficiency and product quality.

 

6. Special Process Adaptation 


In precious metal plating, high-frequency rectifier can significantly improve the flatness and finish of the plating layer, and reduce material loss at the same time.
