If ABS plastic plating wants to improve the pass rate, it is forbidden to do final inspection after all completion. At this time, problems are found and then rework will be wasted, which will waste a lot of work hours and materials. It is necessary to strengthen inter-process inspection to prevent defective products from flowing into the next process and avoid rework of finished products. Because problems can only be easily corrected when discovered in the pretreatment process, if you wait until the plating is completed and then rework, not only will it be too much waste, but it will also be a very troublesome task to remove the coating.
ABS plastic plated products can be reworked and replated. After the coating is removed, the reworked products can be metallized without roughening or reducing the roughening time. However, this rework is limited to 3 times, and some parts can be reworked 5 times. If it exceeds 5 times, it is not suitable for electroplating. At this time, both the adhesion and appearance will be unqualified.
The plating layer can be removed by the general method used for electroplating. For example, removing the chromium plating layer in hydrochloric acid, removing the copper plating layer in waste roughening solution, removing the silver and nickel layer in nitric acid, etc.
However, the step-by-step stripping method is troublesome and takes up several working tanks. Since the plastic material itself is not prone to over-corrosion problems, a one-step stripping method can be used. This method is suitable for products that have been plated with all plating layers, and of course it is also suitable for products that are plated with any plating layer.
Hydrogen peroxide should be added less and replenished frequently. If you add too much at one time, it will cause serious heat and cause deformation and other problems. In addition, for coatings coated with decorative chromium, the chromium can be removed in concentrated hydrochloric acid before using this stripping solution.
