Abstract

PURPOSE: To form a thick plating layer locally only on the required part in the stage of electroplating of noble metals or the like by forming a nozzle for injecting a plating soln. into the shape similar to that of the part to be thickly plated and controling the flow of the plating soln. and electric lines of force.
CONSTITUTION: An elastic material sheet 2 provided with a through-hole 5 for partial plating and a receiving frame 3 are fixed to an object 1 to be plated, and an insulation characteristic nozzle 14 and an insoluble anode 15 are disposed. With the object 1 in the hole 5 as the cathode, a plating soln. is injected to plate noble metals such as gold, silver or the like on said part. Here, the nozzle 14 is provided with one or plural holes for injection of the plating soln. and is made into the shape similar to that of the part to be thickly plated. The shape of the thick-walled part of the plating layer is defined by setting the anode 15 in the position of a shaded part 22, that is, in the position where the thinly plated part is kept free from direct injection of the plating soln. from the nozzle injection ports and shielding the electric lines of force other than the thickly plated part with the nozzle. The inter-electrode distance is set within 20mm, whereby the thick-walled plating layer is formed only on the required part and the waste of plating by noble metals is eliminated.
