In the processing of china aluminum die casting products, cleaning is an indispensable part of electroplating. Most of the problems are related to cleaning. If the cleaning process is not passed, then there may be defects such as mottle and stains in the coating.
The water quality requirements of electroplating cleaning water are very strict. Different processes and plating types have different cleaning water quality. We can divide two major points according to the process.
1. The pre-treatment cleaning water does not have very high water quality requirements, and the cleaning water before electroplating can be satisfied with tap water. It is best to use pure water for the final wash before entering the plating tank. Since pure water contains magnesium and calcium ions, it will affect the plating layer, causing the plating layer to become brittle, foggy, and streaked. For cost considerations, it is best to use pure water for the first washing out of the plating tank, so that the first washing water with a higher concentration can be recycled and reused.
2. Temperature is also the key to electroplating. The plated parts after electroplating should be scalded with hot water before drying.
