  • Patent number: 6228230
    Abstract: An apparatus for electroplating small parts comprises an electroplating bath for holding an electrolyte and electroplating anodes. The apparatus includes a container having at least one screened parts compartment for holding the parts to be electroplated, and incorporates an electrically conductive screen as its base portion, on which the parts are settled. The conductive screen is adaptable to be connected to the negative pole of a power supply to function as the cathode. A pump circulates freshly ionized electrolyte into the parts compartment and directs a flow of the electrolyte to periodically tumble the parts in the parts compartment. Thereafter, the parts are shaken by a shaker to level the parts to maximize the surface and electrical contact between the parts and the screen when they are settled on the screen. In alternative embodiments of the invention, the container can be of perforated panel construction.
