ABSTRACT:
A method of electroplating helical rotors provides uniform plating depth. A positive pole electrode having a bore with the same configuration as the rotor receives the rotor, which is the cathode. The bore is larger than the rotor, providing a uniform width clearance. Electrolyte solution is pumped through the clearance while electrical current flows to cause plating. The rotor is rotated and advanced during plating.
