Roll forming is a continuous bending operation in which a strip of metal each performing only an incremental part of the bend, until the desired drawing profile is obtained.Roll forming is ideal for producing parts with long lengths or in large quantities with a minimum amount of handling as compared to other types of forming. The roll forming machine is very important in making sure that the final product is up to standards that the client needs. For some companies, they regularly update their equipment to make sure that they provide the best services. Without the best equipment, it will be hard for clients to keep bringing in more orders because of the poor work.  In addition, we design the machine depends on the drawing profile. And now many drawing profiles can be produced, but each profile requires a carefully crafted set of roll tools. Design of the rolls starts with a flower pattern, which is the sequence of profile cross-sections, one for each stand of rolls. The roll contours are then derived from the profile contours. Because of the high cost of the roll sets, simulation is often used to validate the designed rolls and optimize the forming process to minimize the number of stands and material stresses in the final product. Roll forming machines are now being produced so that for similar products with only a change in part width such as stud and track profiles, a new set of profile rolls is not required. This is achieved by the mill being split along its center line and the web, flange and return sizes are set using a control panel that moves the mill rafts centrally to increase or decrease the aforementioned features.
