Description

Technical Field

[0001] The utility model relates to the technical field of electroplating, in particular to an electroplating hanger. Background Art

[0002] Electroplating is a technology that uses the principle of electrolysis to deposit a layer of metal or alloy film on the surface of metal or other conductive materials. This process can not only enhance the aesthetics of the substrate, but also improve its wear resistance, corrosion resistance, conductivity and other physical and chemical properties.

[0003] During the electroplating operation, the workpiece needs to be placed on a hanger, and then immersed in the electroplating solution through the hanger for electroplating. After the electroplating is completed, the hanger is lifted upward and the workpiece is taken out of the electroplating solution.

[0004] As attached Figure 3 As shown, after the cylindrical workpiece 20 is placed on the hanger 21 and immersed in the electroplating solution, air entrapment is likely to occur on the inner side of the cylindrical workpiece 20 and an air trapped area 22 is formed. The electroplating solution cannot enter the air trapped area 22, and an electroplating layer cannot be formed on the inner surface at the position of the air trapped area, resulting in the electroplating layer being unable to completely cover the inner surface of the cylindrical workpiece 20, seriously affecting the electroplating quality.
