ABSTRACT:
A method for electroplating small workpieces includes the steps of: (A) providing a rotatable barrel which has an axis of rotation and a plurality of spaced-apart partition plates disposed one above the other; (B) mounting the barrel in a plating tank with the axis of rotation being inclined with respect to a horizontal line; (C) feeding a batch of the workpieces into the barrel; and (D) allowing the workpieces to fall down by gravity from one of the partition plates to the other one of the partition plates by rotating the barrel.
