The bending technology area includes all manner of machines and processes for bending sheet metal, including press brakes, folders, panel benders, corner formers, ironworkers, notchers, orbital formers, and roll benders. It also has information on accessories such as gauging and backgauging systems.

These days, plate rolls are forming plate 6 and 7 inches thick--and even thicker. Vessel designs that would have been forged just a decade ago are now being sent to fabrication houses. The variable-geometry plate roll system, which really operates more like a press brake than a traditional plate roll, is making such extreme rolling possible.

Tread plate and perforated sheet present significant bending challenges. To help matters, fabricators may need to look beyond typical air bending with a punch and V die. Though bending alternatives vary, they have one commonality: They clamp down to ensure the workpiece stays where it should.

Emerson Network Power's Liebert Precision Cooling facility wanted to implement the idea of one-piece flow on its shop floor in Columbus, Ohio, but the only way that was going to happen effectively was with the introduction of an automated bending cell. The company found its answer with an electric panel bender from Prima Finn-Power.

The increased use of advanced high-strength steels (AHSS) have caused many fabricators to rethink the way they bend metal. AHSS have a relatively high springback associated with it, so much larger overbend angles are generally required. Rotary bending technology is a suitable way to product that overbend angle.

By regularly checking the four key areas of a press brake—hydraulic circuits, mechanical systems, electrical systems, and tooling—the operator can help to ensure that the brake is always ready to tackle the next bending job.

Challenged with shorter product life cycles and increased global competition, OEMs and job shops are looking for more flexible design and production equipment. All-electric, multisense tube benders are designed to meet their needs.

Streamlining bending operations at a Chicago area fabricator was instrumental in the company's lean manufacturing efforts. Batch sizes and lead-times both have plummeted in recent years.

The lack of communication about metal fabricating practices and formal documentation of those processes is a real shame. Metal fabricators may be engaging in shop floor practices that just don't make sense from an efficiency and safety standpoint, and they may not be willing to change if allowed to use these processes over an extended period of time. Metal fabricating he was left alone on the shop floor and how that led him to develop a better way to bend bar stock in a press brake

While it may seem as though movies and popcorn have always co-existed, the automatic popcorn machine actually was invented by Charles Cretor in 1893—before the first motion picture premiered. A century and a quarter-century later, manufacturer C. Cretors & Company, Chicago, celebrates its anniversary, success, and outright survival—bending and adapting through two world wars, the Great Depression, the advent of automobiles, television, the electronic age, dot.comera, globalization—and motion pictures.
