Abstract:
An electroforming apparatus, comprising:a container unit for storing a plating solution; a cathode part placed in said container unit for holding an object to-be-plated; and an anode part placed in said container unit facing with said cathode part, wherein a current-conductive opening of said anode part is formed to have an area larger than that of a current-conductive opening of said cathode part; wherein said cathode part is placed in an inclined posture at a certain angle; wherein the current-conductive opening of said anode part is formed to have an area within a range between two and three times as large as that of the current-conductive opening of said cathode part; wherein said anode part comprises a titanium basket, and said electroforming apparatus further comprises: a diaphragm and a shield plate respectively placed between said titanium basket and the object to-be-plated on said cathode part; a first piping part for feeding a plating solution to a space between said titanium basket and said diaphragm; and a second piping part for feeding the plating solution to a space between said cathode part and said shield plate; and wherein said shield plate has an opening in the center, and a punched hole part having a plurality of punched holes is formed in the outer periphery of said opening.
