Electroplating is the use of electrochemical methods to reduce metal ions to metal and form a smooth and dense metal coating on the surface of metal or non-metal products. The performance of the plating layer after electroplating has largely replaced the nature of the original matrix, playing a decorative and protective role. With the development of the decoration industry and the increase in demand for film protection, people have higher and higher requirements for electroplating quality. However, the current electroplating technology still has some defects, such as long processing time, poor coating thickness uniformity, defects prone to coatings, and large internal stress. These deficiencies limit the application and development of electroplating technology, and cannot adapt to current production, especially the needs of precision manufacturing. The power supply used in electroplating production has a great influence on the quality of the coating.

The lower the frequency, the greater the peak current, that is, within the time of the pulse width, the metal ions close to the cathode will decrease sharply. Since the deposition rate of the matrix metal is faster in a relatively short period of time, the rate of transport to the cathode and embedding in the plating layer cannot keep up with the deposition rate of the matrix metal. Therefore, in order to improve the quality and efficiency of the coating, the frequency and pulse width of the pulse power supply can be appropriately adjusted according to different coating metal solutions. Realize the change to the peak current.

The practice of electroplating workers at home and abroad has confirmed that digital pulse electroplating is a new electroplating technology that can not only improve the quality of the coating, but also increase the deposition rate. Intelligent pulse power supply is a better way to improve the electroplating process. As long as the corresponding parameters such as pulse width, frequency, temperature, etc. are set according to the requirements of different coating metal solutions, the intelligent pulse power supply can automatically complete the electroplating processing of the workpiece.
