With the improvement of the building industrialization level, the processing mode of the reinforcement cage is gradually changed from the traditional manual binding to the full-automatic seam welder.

In the process of manufacturing the reinforcement cage, in order to enhance the resistance to pulling of the pile foundation and the strength of connection with the bearing platform, the segments of the main bars (longitudinal bars) usually need to be bent in advance to form what is called a bending head.
