ELECTROFORMING SYSTEM AND ELECTROFORMING METHOD |
摘要 |
An electroforming apparatus and an electroforming method that are capable of readily shaping an electroformed piece with high accuracy (particularly shaping of a spot-faced configuration or the like in a hollow portion) are provided. An electroforming tank 1 is provided with an air supply device 11 to form an air bubble layer 12 on the surface 3 of an electrolyte 2. A tapered portion 52 is formed at the upper end of a primarily electroformed piece 51 in the air bubble layer 12 by controlling the vertical movement of a bus 50. A secondarily electroformed piece 53 is formed on the primarily,electroformed piece 51 and the bus 50, whereby a spot-faced portion 55 patterned on the tapered portion 52 is formed in a hollow portion 54 of the secondarily electroformed piece 53. <IMAGE> |
