Abstract: An electroplating apparatus of small articles comprising: a horizontal circular bottom disk fixed on a top of a vertical drive shaft concentrically, a cover having a bottom fixing flange extending outwardly, upper opening and forming between the bottom disk a treatment room the height of the room changing gradually low as the radius increases or simply cylindrical, a minus contact ring or intermittent minus contact ring disposed between the bottom disk and flange, porous ring being disposed near the contact ring allowing only to pass an electroplating liquid in the cover by centrifugal force, supply pipes supplying electroplating liquid etc. from the opening, a cellar receiving electroplating liquid etc. scattered from the porous ring, a pump feeding the liquid gathered in the cellar to the supply pipe, an anode inserted from the opening and contacting electroplating liquid, and during the electroplating, the bottom disk and cover repeat rotation and stopping or rotation and decelerating.

Abstract: A plating apparatus of a plating liquid injection type comprises a plating bath, which is filled with plating liquid, for accommodating a plurality of block-like works, plating liquid injection mechanisms disposed at opposite sides of the works for injecting the plating liquid toward the works, the plating liquid injection mechanisms including a plurality of plating liquid injecting portions which are spaced from each other and are adjustable at injection angles thereof, an overflow tank arranged outside the plating bath for collecting the plating liquid overflowed from the plating bath, and a plating liquid returning mechanism including a pump and connecting the overflow tank to the plating liquid injection mechanism, the plating bath being adapted to foam a storage tank for storing the plating liquid when the pump stops.
