HARD CHROME PLATING METHOD FOR VERTICAL TYPE AND HARD CHROME PLATING DEVICE

摘要

PROBLEM TO BE SOLVED: To make it possible to apply plating of a uniform and precise thickness, to eliminate the need for a precision polishing stage for making the thickness of plating uniform, to drastically reduce the time before completion of products and to drastically reduce a production cost.;SOLUTION: A plating tank 1 into which a long-sized member to be plated is perpendicularly immersed in disposed and a supporting stand 2 is mounted above the plating tank 1. A connecting body 3 of conductive material freely attachably and detachably connected to the top end of the member to be plated and a revolving shaft 4 of conductive material which is connected to the upper part of the connecting body 3 and energizes and supports the member to be plated are freely rotatably supported at the supporting stand 2. A plurality of carbon terminals 6 are brought into pressurized contact with a disk-shaped conductive plate 5 fixed to the top end of the revolving shaft 4 to energize the member to be plated in the plating tank while rotating.;COPYRIGHT: (C)2000,JPO
