The rolling process is a cold forging process. There are many materials that can be rolled into shape. Among them, low carbon steel is a commonly used material for roll forming, and non-ferrous metals are more suitable for roll forming.
Roll forming parts are generally made by forging blank parts through a cold heading machine and then rolling them through a thread rolling machine. Equipment that can perform thread rolling and roll forming include: various reciprocating flat plate thread rolling machines, planetary thread rolling machines, two-cylinder thread rolling machines, three-cylinder thread rolling machines, etc. The most common type used for roll forming is the reciprocating flat-plate thread rolling machine. Therefore, for manufacturers equipped with cold heading machines and thread rolling machines, it is just a matter of designing the roll forming mold.
