Apparatus for mass electroplating of bulk goods

Abstract

An apparatus for the mass electroplating of bulk goods comprising a plating tank for the acceptance of an electrolyte, a goods carrying dish immersed in the electrolyte and rotatable around an inclined axis, a disk-shaped electrode immersed in electrolyte and extending mainly parallel to the floor of the carrying dish characterized by the floor of the carrying dish having a helically extending track which will spread the goods throughout the floor during a plating operation. The helical track preferably has a saw-toothed cross section and the dish preferably has one sliding door in a peripheral wall to enable discharge of the goods from the dish after the plating operation. The plating tank is preferably gas tight and is provided with admission and discharge locks so that it is particularly useful for mass aluminum-plating utilizing an aprotic, oxygen-free and water-free, aluminum-organic electrolyte.
