でコスト高になるという問題があった。Traditionally, many reinforcing bars bending machines have been used for relatively small-diameter reinforcing bars, and in the case of large-diameter reinforcing bars between 25 and 75 mm that cannot be processed with conventional bending machines, molding using a large press is required. Bending, or hot-working, requires a large number of people to perform the bending process, which causes problems such as damage to the bending part of the reinforcing bars, trenches, and the need for a large number of people to perform the bending process. In the case of partial processing, there is a problem in that the cost is high due to the cost of the heating source.
