[0002] Flanging refers to a forming method that uses the mold to form a straight wall or flange with a certain angle along the edge of a closed or unclosed curve on the flat or curved part of the blank. Flanging is a type of stamping process. There are many types of flanging, and the classification methods are also different. Among them, it can be divided into elongation flanging and compression flanging according to the deformation properties.
