[0002] The product needs to be cleaned before electroplating. The main purpose of cleaning is to remove dirt, oil, oxides or other impurities on the surface to ensure the quality and adhesion of the electroplated layer. The cleaning process can use a variety of cleaning agents, such as water, organic solvents or acid and alkali solutions, depending on the material of the product and the nature of the contaminants. After cleaning, the surface of the product should be clean and free of oil, ready for electroplating. Therefore, it is very important to clean the product before electroplating.

[0003] At present, direct water flushing is usually adopted for cleaning metal tubes, that is, the water flowing out of the water pipe directly flushes on the plated tube. The plated tube is flushed with water for a very short time, and the residual liquid on the surface is often not completely removed. The cleaning of the plated tube is not clean and thorough enough, which affects the quality and adhesion of the electroplating of the metal tube. Utility Model Content
