When the rail 5 is supplied with the plating liquid, the plating rack supplies a current to the inside of the rail 5, thereby making the rail 5 a cathode. Under the action of an external electric field, free metal ions in the electroplating solution are reduced into metal atoms, metal deposition is carried out on a cathode, and finally an electroplated layer on the surface of the guide rail 5 is formed. However, since the hollow guide rail 5 is provided with the U-shaped cavity, the electroplating quality of the U-shaped cavity cannot be guaranteed in the electroplating process.
In the prior art, the hollow guide rail 5 is usually hung on the electroplating rack in a horizontal posture, and the U-shaped cavity on the guide rail 5 is perpendicular to the lifting direction of the electroplating rack.
