workpiece into a series of three rollers - two at the bottom and one at the top. Whilst the bottom two rollers are usually static and serve to support the workpiece, the position of the top roller can be adjusted according to the position and radius of the required bend. As the workpiece is fed through the roller system, it will bend in accordance with the top roller's position.
Roll bending is usually performed on strong, but flexible materials. Some of the more commonly-used materials within the roll bending process include carbon steel, aluminium, mild steel, stainless steel and copper.
Roll bending is a cost-effective process, making it suitable for both low and high-volume requirements. However, some secondary processes may also be required to improve aesthetics post-production - in addition, some materials will respond better to roll bending than others.
