The rolling process is a cold forging process, and there are many materials that can be rolled. Among them, low-carbon steel is a commonly used material for rolling. Nonferrous metals are more suitable for rolling.

Rolled forming parts are generally made by cold forging machine upsetting forging, and then processed by thread rolling machine. The equipment that can perform thread rolling and rolling forming are: various reciprocating flat thread rolling machines, planetary thread rolling machines, two-cylinder thread rolling machines and three-cylinder thread rolling machines. The most commonly used for roll forming is the reciprocating flat thread rolling machine. Therefore, for manufacturers with cold heading machines and thread rolling machines, it is only a matter of designing the roll forming mold.
