From the frames cornering office partitions, to the structure holding a car window, the metal forming technique called roll forming is responsible for making metal get bent out of shape.
Roll forming is a metal forming process typically involving strips of coiled metal passed continuously through successive roll dies or rolls into a desired shape.
Imagine how an opened paper clip laid flat on the table would look like, this is generally the “before” of the roll forming process.
Now, imagine bringing both ends of that paper clip as close as possible to form its typical configuration of two bends at each side, at a continuous rate to build upon this shape: this is a typical ”after” cross-section of a completed roll form application.
Commercial products such as door frames, to fenders and bumpers, to even bicycle rims benefit from roll forming because these parts tend to have longer lengths and are mass-produced in high volumes.
Roll forming insight number one: versatility
Roll forming is appropriate for almost all metals. Most common materials such as carbon, galvanized and stainless steel, brass, copper, zinc and titanium are roll formed, as well as various pre-finished metals. Characteristically, the more malleable a metal, the better it will respond to roll forming.
Roll forming insight number two: viability
Designated as an economically viable and highly repeatable process, metal roll forming benefits include the elimination of secondary operations, such as piercing, notching and deburring, which effectively bumps up production speeds.
Another major advantage of roll forming is the reduced inventory, labour and material costs due to roll formed material having structural strength over and above other metal forming processes. Plus, a custom roll former provides finished components of unique and specific lengths essentially eradicating scrap metal loss.
Roll forming insight number three: diversity
The biggest benefit of all when it comes to roll forming is that any industry can gain value using standard or custom roll formed parts.
Because of the roll former flexibility to adhere to tight tolerances, as well as provide multiple lengths using the same set of tool, initial investment costs are greatly minimized. Applications requiring numerous process operations also benefit from a roll formed design because of its uniform consistency and repeatability profiles.
