PURPOSE:To permit easy control of reaction time and to enable extra-thin plating by communicating the bottom of a plating cell constituted of a filter body with a suction means via a cock. CONSTITUTION:A plating cell 10 is placed on a filter device 20 and the bottom thereof is formed of a filter medium 24 in the upper part of a funnel-shaped body 25. A three-way cock 30 is mounted to the top end of the leg part of the body 25 and while the cock is held closed, the medium 24 holds thoroughly the plating liquid. The other two ports which are not communicated with the funnel leg part of the cock 30 are communicated respectively to a washing water reservoir 50 and a plating liquid reservoir 60 by conduits, which reservoirs 50, 60 are connected by suction bottles to suction means. Then when the cock 30 is opened after plating in the cell 10, the plating liquid is discharged quickly and the quick sepn. of the plated powder and granular material and the plating liquid is made possible. The reaction time is thus terminated in short time and the formation of the extra-thin plating is possible as well. |
