When doing the Hull bath test, why does the test piece plating always fail to correctly reflect the bright performance of the hard chrome additive? The reason may be that the heating and cooling are not done properly. Understanding the importance of heating and cooling will help us to make fewer mistakes and quickly judge the performance of additives.
Some customers have asked that when we use the army green passivation solution, what are the operation specifications to pay attention to? In general there are 4 points, this issue of the article we will talk about it.
In the electroplating industry, the appearance of white fog streaks on the surface of the tin layer is a common and troublesome problem. This defect not only affects the aesthetics of the coating, but also may adversely affect the performance of the coating, such as reducing corrosion resistance and weldability. As a research and development engineer of tin plating brightener, I will explore in depth the causes of white fog striations after tin plating, and explain why the choice of tin plating brightener Sn-807 can effectively solve this problem.
It is commonly believed that during the use of electroless nickel concentrates, the plated parts are plated more uniformly because they are not disturbed by power lines. Is this view correct? Actually, it is not.
Plastic plating process as a more mature process, people for the plating quality requirements are higher and higher, but for a variety of reasons, the plating plant in the production process will encounter some plating faults, such as pitting. So what are the causes of pitting? What is the relationship with the performance of alkaline electroless nickel plating additives?
Electroless nickel solution in the application process, to regularly analyze the electroless nickel plating solution, when it is found that the nickel ion consumption is fast what is the reason?
