  • Electroplating drum for relatively large fasteners and the like
    Patent number: 4062751
    Abstract: Relatively large parts, such as large fasteners and the like, are mass electroplated in a plating drum rotatable in a plating solution, without damaging contact of the parts with one another, by confining the parts in separate plating cells of the drum containing openings for circulation of plating solution through the cells and electrodes between which the parts move back and forth during drum rotation to effect exposure of the entire surface area of each part to the electroplating action.
