Advantages and disadvantages of roll bending. The Advantages of the 4 Roll Plate Rolling Machine

Efficiency Roll forming is an energy efficient process usually requiring no process heat to be added. Custom Colors. Allowing for natural spring back of the material, this radius remains uniform irrespective of whether the shape of the part being formed is a complete circle, or is only a segment of a circle. Prepainted steel can be substituted for post-painting methods and the metal can be perforated prior to roll forming or, if the hole pattern is close to the beginning or end of the part, the formed part can be perforated in the cut-off die. The system can control alignment, pre-bending and rolling centrally. The advantages of roll forming are speed, economy of scale, the ability to incorporate secondary operations such as punching and notching in-line, the ability to form complex shapes that can not be brake formed, and the ability to produce extra long shapes that can not fit into a brake press.
