Even with adequate management, plating defects may occur due to material defects, poor pretreatment, or stains that arise during drying. In cases where the plated parts are expensive or when the customer provides the items, the plated items can be immersed in a stripping solution, or an electric current can be passed while the items are immersed in the stripping solution to remove the old plating before re-plating. When selecting a stripping solution, key points include not damaging the substrate, being able to strip quickly, having a low burden on wastewater, and ensuring high safety during operation. Particularly, nickel and nickel alloys can become non-conductive due to the stripping solution, so it is extremely important to choose products suitable for both the material and the plating film. We will propose the optimal stripping agent based on the type of base metal and plating film. Additionally, we can introduce processing locations, so please feel free to consult with us first.
