METHOD FOR MANUFACTURING METAL TUBE

摘要

PROBLEM TO BE SOLVED: To improve the ratio of extraction of wire and to improve productivity in a metal tube manufacturing method in which electroforming is performed using a metal wire 9 as a mandrel and then the wire 9 is extracted. SOLUTION: The following means is adopted: a metal wire with high elongation percentage is used as the wire 9 to be used as the mandrel.
