According to the shape of the blank and the edge of the workpiece, flanging can be divided into inner hole (round hole or non-circular hole) flanging , plane outer edge flanging and curved surface flanging, etc. Flanging can replace the deep drawing process of some complex parts, improve the plastic flow of the material to avoid cracking or wrinkling.
