Electroplating is the process of plating a thin layer of Other metals or alloys on some metal surfaces by electrolysis. It is a process of attaching a metal film to the surface of metal or other materials by electrolysis to prevent metal oxidation ( Such as rust), improve wear resistance, electrical conductivity, light reflectivity, corrosion resistance (copper sulfate, etc.) and enhance the appearance of beauty. During electroplating, a plated metal or other insoluble material is used as an anode, and a workpiece to be plated is used as a cathode, and a cation of the plated metal is reduced on the surface of the workpiece to be plated to form a plating layer. In order to eliminate the interference of other cations and make the plating layer uniform and firm, it is necessary to use a solution containing a plating metal cation as a plating solution to keep the concentration of the metal cation of the plating layer unchanged. The purpose of electroplating is to plate a metal coating on the substrate to alter the surface properties or dimensions of the substrate. Electroplating enhances the corrosion resistance of metals (the corrosion-resistant metal is mostly used for plating metals), increases hardness, prevents wear, improves electrical conductivity, smoothness, heat resistance and surface aesthetics.
Electroplating is divided into hanging plating, barrel plating, continuous plating and brush plating, etc., mainly related to the size and batch of the parts to be plated. Hang plating is suitable for general-sized products such as bumpers for automobiles, handlebars for bicycles, etc. Barrel plating is suitable for small parts, fasteners, washers, pins, etc. Continuous plating is suitable for wire and strip production in batches. Brush plating is suitable for partial plating or repair. The electroplating solution is acidic, alkaline and acidic and neutral solution with chrome mixture. Regardless of the plating method, the plating tank and hanging hanger which are in contact with the product to be plated and the plating solution should have a certain degree. Versatility.
