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.

New ways to increase production, reduce labor costs, and maximize floor space may be found by revisiting a 50-year old technology—rotary punching. Many part features and patterns can be punched and formed using pull-through rotary units at up to 300 feet per minute(FPM) in materials as thick as 1/16 inch. In addition, cam technology allows rotary punching and forming of material thicknesses up to 0.105 in. (12 gauge). Servo drives empower line speeds as fast as 650 (FPM).

Compensating for gauge changes in precision roll forming doesn't necessarily require significant investment. Spaces, the use of gauge spacers, and other technique can help when roll forming parts of multiple gauges.

Roll-Kraft has released a portable hemming unit. The machine forms 180-degree hems on the edges of a flat strip of metal. Hems are found primarily on lighter-gauge material to strengthen the profile or improve safety in handling.Typically, the hems are formed before the metal strip is introduced...

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.

Whether maintaining or changing the OD, knowing the basics of end forming—especially friction and lubrication—can help achieve a successful result.

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.
