A barrel assembly, such as an electroplating barrel (13) according to the invention is divided into two kinds, one of which provides perforations (21) and liquid passageways (20) narrower than the diameter of said perforation to communicate between the perforations, while the other provides with liquid passage means so designed that the exterior opening (43b) is wider than the interior opening (43a), whereby, upon withdrawing the barrel from an electroplating tank containing a liquid plating solution, said solution is facilitated to flow out through said perforations and through said passage means for drainage. |
