Roll forming is developed from spin forming. It is to change the type knife into a rolling head. The rolling head and the model each rotate around a fixed axis, and the plastic mud placed in the model is stretched and pressed into a green body. The shape and size of the green body completely depend on the "cavity" formed by the rolling head and the die surface.
The rolling method can be divided into male mold rolling and female mold rolling. Compared with spin forming, roll forming has the advantages of high density of the blank, large mechanical strength, small deformation, low labor intensity, and easy mechanization and automated production.
