Roll forming machines are automated machines that use a series of roller dies to form sheet metal into specific shapes. The sheet metal is passed through each set of rollers, which progressively form it into the desired shape. The roll forming machine can be used to make parts for a variety of industries including automotive, aerospace, HVAC, and furniture. The machine is typically used to form complex shapes and contours that are not possible with traditional stamping or cutting methods. Roll forming machines are often used in the production of roofing, gutters, ductwork, and framing members.
