Rotary punching revisited

August 6, 2009 | By Paul Williams

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).

Continuous improvement for roll forming - Part I

March 10, 2009 | By Andy Allman

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 Hanhui Li

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.
