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 ...

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...

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 move...

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 ...

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 t...

When deciding wheher or not to produce roofing panels, you need to determine your ROI, based on if you can use existing equipment or need new equipment, the required panel appearance; possible line configuration; and material handling options.

Roll forming of roofing components for the pre-engineered building and component industries presents unique challenges for manufacturers. Tighter profile tolerances, wider product ranges, and compressed lead times present production challenges for producers running older equipment or those contempla...

In roll forming, non-stop punching and shear systems have traditionally employed simple open-loop control methods. Closed-loop (also called servo-based) systems can overcome many limitations of the open-loop design and yield higher line speeds, reduce downtime, and reduce scrap.

Roll-formed parts are subject to end distortion when the parts are cut at the end of the roll-forming line. Understanding the forces that contribute to end distortion is the first step to balancing the forces and eliminating end distortion.

Understanding the relationship between the elevation of the entrance guide and the shape of the roll formed strip is crucial to satisfactory roll forming. The entance guide elevation, if improperly set, can cause the strip to bow and twist as it leaves the first forming pass. Setting the elevation p...

Roll forming, often called open-section forming, uses successive sets of roller dies to bend a strip of steel progressively until the desired shape is achieved. This process is very similar to traditional tube- and pipemaking, but differs in that it can form more complicated sections.
