In the production process of electroplated products, the reasonable maintenance of the plating solution involves not only changes in the main salt components of the plating solution, but also the continuous accumulation of impurities or accidental intrusion under certain circumstances. This requires us to understand the causes, methods, and fault phenomena of common impurity introduction. This provides assistance for analyzing and solving problems when they occur. There is a good experimental method, namely the Hull cell test method, which is very helpful for us to understand impurities and their impacts, as well as for the analysis and supplementation of additives. We should master this method. Of course, as the number of problems encountered and resolved in production increases, personal experience will accumulate, and the level of production maintenance will improve, naturally enhancing the stability of the company's product quality. This is a scenario that companies are willing to see, and it is also a control ability that personnel with higher technical levels must possess. A necessary understanding of the processing object For the objects, processing requirements, and processing conditions that the electroplated products are to be processed, a necessary understanding should be had. The quality of the product is relative to a certain processing object and meeting its requirements. The variety, hardness, brittleness, and toughness of the processed material, whether the processing conditions are dry grinding, wet grinding, pressure level, required surface condition, whether it requires processing for sharpness, outstanding durability, etc., all have different impacts on our selection of abrasive variety, grade, particle size, choice of plating solution type, formula, process, and electroplating parameters. Especially when developing new products, comprehensive and authentic records of each test data such as grinding conditions and results are necessary. These are important bases for us to test and improve the product again. Because when the feedback of grinding results shows deviations, the direction of product improvement is wrong, and the results will only get worse with further changes.
