In the plastic plating process, the quality of the plating layer is very important, among which pinholes and pitting are common defects, which directly affect the appearance and service life of plastic products. To solve these problems, Bigely developed the roughening additive PL-2, which has shown good results in the application of plastic plating.
Electroless copper plating is a process in which copper ions are reduced by reducing agent and deposited on the surface of conductive substrate without current. The brightness of the coating is one of the important indexes to measure its quality. In order to achieve high brightness of the coating, the choice of additives is very important. The MID rapid electroless copper plating additive HS-ECu-801 developed by Bigely has become the ideal choice for many electroplating plants to pursue high brightness coatings due to its good performance.
Electroplated colored zinc passivation process is vital in the corrosion protection of steel and metal products. The passivation process is mainly divided into two types: trivalent chromium passivation and hexavalent chromium passivation, and each of these two technologies has its own advantages and disadvantages. In this article, a detailed comparison of trivalent chromium and hexavalent chromium passivation will be made in terms of the performance of the passivated film layer, production costs and environmental costs, in order to help plating factories to choose the appropriate passivation process!
Trivalent chromium blue and white passivation liquid is widely used in electroplating industry, mainly for passivation treatment after galvanizing process. Its main function is to improve the corrosion resistance of the coating. However, as time goes by, the passivation solution will gradually age. The causes of aging include the accumulation of organic impurities, the composition of the passivation solution is not uniform, the change of pH value, the solution temperature and metal ion pollution. The change of these factors will directly affect the performance of passivation liquid, and then lead to a series of plating failures.
The pH value of Bigely neutral tin plating process is nearly neutral, which is suitable for the plating of materials susceptible to acid, alkali influence or corrosion, such as special glass, ceramic materials as the substrate of the component solderable ends, leads. So, how should we maintain the plating solution in daily production?
Matte tin plating is a widely used electroplating process used to deposit a uniform layer of tin on metal surfaces to provide corrosion protection, increase solderability and enhance appearance. This tin layer has a certain "matte" or "non-glossy" effect, as opposed to shiny tin plating, and is characterized by the following:
