Abstract
PURPOSE: To perform plating of a uniform thickness and a smooth surface, by putting the metallic tube to be plated of which one end is closed, making its closed end a top and setting a clearance, to the outside of a cylindrical electrode protruding perpendicularly from the surface of a plating liquid, contacting another end of the metallic tube to the surface of the plating liquid and erupting the plating liquid inside the metallic tube.
CONSTITUTION: The metallic tube to be plated 1 having one end closed is put in, making its closed end a top and setting a clearance, to the outside of the cylindrical electrode 8 protruding perpendicularly above the surface 7 of the plating liquid of a plating bath 2 and another end is contacted to the surface 7 of the plating liquid. By this the plating liquid 3 is erupted inside the metallic tube 1 through the cylindrical electrode 8 via a pump 9, a piping 10 and the inside of the metal tube 1 is filled with the plating liquid 3. The plating liquid 3 which flows down enters in the plating bath 2 and is supplied again to the cylindrical electrode 8 via the pump 9, the piping 10.
