Abstract (en)
[origin: EP3263240A1] A producing method to be disclosed is a producing method for producing a formed metal item that includes a tubular part (1e) with a slit (3). This producing method includes a step (i) of forming U-shaped part having a U-shaped cross section by deforming a metal plate, and a step (ii) of forming the tubular part (1e) with the slit by deforming the U-shaped part using a die assembly (20) with a protruding part (23) in such a manner that two end parts of the U-shaped part clamp the protruding part. In step (ii), a cross-section peripheral length LH of the tubular part (1e) is made shorter than a cross-section length LU of the U-shaped part.
