The roll forming process is mainly processed by forming a movement of materials into various shapes of rollers, shafts, valve cores, and special fasteners.

Rolling deformation is a line contact, which is carried out continuously and stepwise, and the required deformation force is small, and one stroke can produce one or several workpieces.

Compared with the cutting and grinding processes, the roll forming process not only has high production efficiency, saves materials, but also has high product strength and stable quality. This process is especially suitable for processing workpieces with long and short machining difficulties, especially for the annual production. Millions of high-volume products are most advantageous with the roll forming process and the most economic benefits.

The rolling process is a cold forging process, and there are many materials for roll forming. Among them, low carbon steel is a commonly used material for roll forming, and nonferrous metal is more suitable for roll forming.
Roll-formed parts are generally obtained by forging a blank piece by a cold heading machine and then rolling it by a thread rolling machine. The equipment for thread rolling and roll forming includes various reciprocating flat wire rolling machines, planetary rolling machines, two cylindrical rolling machines, and three cylindrical rolling machines. The most common type of roll forming is the reciprocating flat wire reeling machine. Therefore, for manufacturers equipped with cold heading machines and thread rolling machines, it is only a problem of designing a rolling forming mold.
