PRODUCTION METHOD FOR ELECTROFORMED PIPE, ELECTROFORMED PIPE, AND FINE WIRE ROD FOR PRODUCING ELECTROFORMED PIPE

摘要

PROBLEM TO BE SOLVED: To easily remove a fine wire rod from an electroformed part or an surrounded part formed by electroforming.;SOLUTION: The electroformed pipe is produced by forming an electroformed part around a fine wire rod 30 by electrodeposition, and removing the fine wire rod 30 from the electrodeposited part. The fine wire rod 30 is removed by heating the electrodeposited part and thermally expanding the same, or cooling the fine wire rod 30 and shrinking the same to form a gap between the electrodeposited part and the fine wire rod 30, and using a method of holding and pulling the fine wire rod 30, or sucking the fine wire rod 30, or physically pushing the same away, or jetting a gas or a liquid and pushing the same away.;COPYRIGHT: (C)2004,JPO
