ELECTROFORMING SYSTEM AND ELECTROFORMING METHOD

摘要

An electroforming system and an electroforming method in which shaping of an electroforming body especially, counter-boring in a hollow section can be carried out easily and accurately. An air supply unit 11 is disposed in an electroforming bath 1 and an air bubble layer 12 is formed on the liquid level 3 of electroforming liquid 2. A tapered part 52 is formed at the upper end of a primary electroforming body 51 in the air bubble layer 12 by controlling up/down movement of a bus 50. A counter bore part 55 copying the tapered part 52 is formed in the hollow section 54 of a secondary electroforming body 53 by forming the secondary electroforming body 53 on the primary electroforming body 51 and the bus 50.
