I am Mr. Li, the head of a manufacturer focusing on nickel plating of copper and aluminum parts. However, the workpieces after plating often have problems of peeling and bad bonding, which makes me very distressed. These problems not only affect the appearance quality of the products, but also make our customers lose confidence in our products. I heard that the use of electroless nickel plating process can solve the problem, but this is something I am not familiar with, and I need to seek the guidance of the additive supplier.
In the production process of trivalent chromium color passivation, the gloss of the passivation film is one of the important indicators of its quality. However, the problem of poor passivate film gloss is often encountered in practice. This phenomenon involves a variety of factors, including the composition of the trivalent chromium colored zinc passivator, the quality of the plating layer, and the control of the passivation process.
In the current condition of high environmental protection requirements, traditional Cr(VI) passivators are gradually being eliminated from the market due to their toxicity and pollution.
In the plating process using hard chrome additives, localized non-plating is a common problem. This not only affects the aesthetics and uniformity of the plating layer, but also may lead to a decline in product performance and failure to meet the requirements of use. So, why does hard chrome plating have localized non-plating?
A plating manufacturer in the use of barrel nickel plating brightener, faced with barrel nickel plating workpiece recesses can not be plated, thin plating layer and easy to rust the problem. In the production process, the manufacturer found that it was difficult to achieve the ideal thickness of plating in the recesses of the workpiece after nickel plating, resulting in the workpiece rusting quickly, which seriously affected the quality of the product and production efficiency.
In the electroplating process, degreasing is a crucial step that directly affects the quality of the subsequent plated layer. In this article, we will discuss how to check the degreasing quality of parts after using steel electrolytic degreasing powder.
