ELECTROFORMING APPARATUS AND ELECTROFORMING METHOD

摘要

An electroforming apparatus and an electroforming method that are capable of performing high-precision electroforming are provided. An electroforming tank 1 accommodated in an outer tank 2 is continuously supplied with an electrolyte 3 from a control tank 5, and electroforming is carried out in an overflow layer 10 of electrolyte 3 formed over the electroforming tank 1. A bus 25 for electroforming that is retained by a retaining jig 30 is carried along the overflow layer 10 by a jig transfer device 20. The electrolyte 3 overflowing the electroforming tank 1 is collected into a control tank 5 from the outer tank 2 and supplied to the electroforming tank 1 again after being filtered.
