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.
