In the field of electroplating, deep plating capability refers to the ability of the plating solution to deposit plated layer in the area of high and low current density, which determines the uniformity of the plated layer in the deep holes, blind holes and pits of the workpiece. Tin plating additives play an important role in enhancing deep plating capability.
Electrolytic degreasing in electroplating production is a pretreatment process that utilizes an electrolytic process to remove grease and organic contaminants from the surface of metal workpieces. Cleaning the metal surface prior to plating is critical, as oil and grease can hinder the uniform deposition of the plating layer and may lead to quality problems such as peeling and flaking of the plating layer. Electrolytic degreasing powder is a chemical agent used in industrial production to remove grease and other impurities from metal surfaces, mainly by electrolysis. The following factors should be considered when selecting a suitable electrolytic degreasing powder:
The reason for using hydrochloric acid for plating rust removal is that hydrochloric acid is effective in removing oxidized layers, rust, and other contaminants from metal surfaces. Metal surfaces can easily form a layer of iron oxide, or rust, after prolonged exposure to air. These oxides must be thoroughly cleaned before plating to ensure that the plating layer adheres evenly and firmly to the metal surface.
Zinc alloy die casting is easy to blister, which is a problem for many electroplating factories, because it is related to the straight-through rate of electroplating products, and will affect whether die-casting factory customers will continue to choose them. Therefore, it is very urgent to solve this problem. In this article, we will analyze the importance of pre-treatment wax and oil removal process for improving the binding force of zinc alloy coating.
Parts degreasing is an important process of plating pretreatment, plating parts degreasing quality is good or bad, will directly affect the quality of plating layer. For example, in the previous article, I have mentioned the nickel plating process, degreasing is not complete, it will cause the plating layer pinhole appearance. Therefore, it is very important to do a good job of degreasing. And when we choose alloy electrode degreasing powder, phosphorus-free is a very important index.
In the electroplating process, removing wax is an easily overlooked but important production process. In this article, we will introduce the definition of dewaxing water and the role of Bigely dewaxing water in the electroplating production process.
