1.What is the process of rollforming?
Roll forming is a continuous process which converts sheet metal into an engineered shape using consecutive sets of mated rollers, each of which makes only incremental changes in the forming. The sum of these small changes in form is a complex profile. In conventional stamping the entire part is formed all at the same time.
2.What is the function of roll forming machine?
Roll form machines are designed to make sheet metal into straight formed shapes profiles. The roll forming process takes a continuous flat sheet of metal and power feeds it through a successive series of hardened steel rollers, which station by station shape the metal into a finished shape as it passes through them.
