Automotive Roll Forming

Automotive roll forming machines are an integral part of the parts manufacturing process in today's modern production environment. These large machines take flat rolled steel and form or bend it in to a range of automobile parts. Everything from bumpers, window glides to rocker's and other support sections in the chassis. By rollforming these parts rather than brake pressing or stamping them parts suppliers (tier 1) can offer higher volume, higher quality at a lower cost.

So exactly how does a roll former bend steel in to complex parts?

By slowly bending the metal as it moves through roll tooling the part is formed. Each stand (the section that holds the shaft and rolls) is called a pass. Each pass slightly bends and forms the metal sheet as it passes through the roll former machine. Automotive parts companies often use these machines to form multiple parts on the same line. This efficiency and ability to produce more then one profile is a huge advantage to any automotive tier 1 parts supplier. The number of stands needed to form the part is largely determined by the end product. Auto manufacturers require a highly repeatable and precious profile shape. Automotive roll forming machines provide this over and over.
