Mr. Sun from Dongguan is the owner of a processing factory that specializes in plating chemical nickel on various hardware products, molds, electronic accessories, mechanical equipment, and other workpieces.
Mr. Zhou from Zhangzhou, Fujian, is the boss of a factory engaged in electrotinning of various precision linker. Recently, Mr. Zhou discovered during the production process that the working current range of the tin plating solution is narrow and the current efficiency is low.
Mr. Ding from Zhenjiang, Jiangsu is the owner of a processing factory that specializes in electroplating copper, nickel, and chromium on various automotive parts, electronic components, and other related products. Recently, Mr. Ding discovered during the production process that the acid copper plating solution produces a large amount of organic decomposition products after just a few days of treatment, leading to the phenomenon of pinholes and pitting on the workpiece coating, which seriously affects the quality of the workpiece coating. So Mr. Ding plans to replace it with a stable acid copper additive with fewer decomposition products.
