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.

Continuous improvement for roll forming - Part I

March 10, 2009

By:

Continuous improvement and statistical process control are useful, time-tested techniques—they have been used since the 1950s—but their use must be tailored to specific applications. For example, a typical manufacturing metric is parts per minute, but many roll formers should measure feet per minute. This and other tips can help roll formers accurately evaluate their productivity and measure the impact of process improvements.

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.

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?
