Roll Forming is a cost effective process for shaping metal coils into custom designed profiles. It is used by several industries to produce components for automobiles and appliances to aircraft and construction industries. Listed below are some of the benefits and advantages roll forming offers.
The speed of roll forming is due to the long coils of metal it uses that are rapidly fed into the forming machine. Since the machine is self-feeding, there is little need for human monitoring, which lowers the cost of labor. Punching and notching during pre-feeding avoids the need for secondary operations.
Metals do not need to be heated for roll forming, which significantly lowers energy costs. The careful control and lubrication of moving parts reduces tool wear and the cost of component replacement. The smooth finishes of completed parts removes the need for secondary processes such as deburring or trimming of flash. Parts are produced in large quantities reducing the cost of the final product.
Complex and intricate cross sections can easily be produced using ferrous and non-ferrous metals. In some processes, it is not possible to shape a metal that has been painted, plated, or coated. Roll forming can easily shape them regardless of the type of finish.
Products are more uniform and consistent across a complete run. Tolerances are very tight with extremely precise dimensions. Sharp, clean contours are maintained with the absence of die marks or deformities.
Since the metal is fed into the machine, any length can be produced using the same tooling for any part.
Roll forming produces one to three percent scrap for each production run, which is far less than any other metal working process. The lower amount of scrap lowers the cost of working with expensive metals.
A major problem with bending metal is residual stress, which negatively affects repeatability. The rapid processing of roll forming helps metals retain their residual stress as well as any loss of weld seam control.
