Roll Forming

Successful roll forming requires more than a roll forming line and tooling. Robust finite element analysis software, and understanding the material's yield strength and elasticity, are critical. This technology area is full of information on equipment, tooling, and simulation software.

Understanding bending, moving material in roll forming

September 30, 2008

By:

Roll forming is a matter of two processes: shaping material using localized deformation with a large amount of material movement (in other words, bending and moving the material). Localized deformation (bending) is a permanent bend with a slight thickness reduction at the bending line. Material movement is a matter of relocating or rotating a section, either formed or unformed, without changing its shape. Although roll forming engineers often address these processes at the same time, it can be helpful to consider forming and movement separately.

Edge treatments for roll formed parts

May 13, 2008

By:

According to OSHA and BLS data, safety in metal manufacturing has been improving. Workplace injuries and injury severity fell from 2000 to 2006. The biggest improvements have been in severe injuries, so minor injuries have gotten more attention lately. One such minor injury is cutting. Roll formers can do their part to prevent workplace cuts by focusing on deburring.

Rolling to market - Part I

March 11, 2008

By:

For many jobs, the toughest part isn't roll forming the parts themselves—it's getting those parts to the customer. Parts are cut-to-length, then placed on immense wooden frames in such a way that allows the maximum load on a truck. That's a lot of material handling. But what if a shop eliminated the packing altogether by taking the roll forming to the job site itself?
