Roll forming machine is a type of machine used in the manufacturing industry to form sheet metal into specific shapes and sizes. It works by feeding a sheet of metal through a series of rollers, each of which applies pressure to the sheet to bend it into the desired shape. The rollers are arranged in a specific sequence, determined by the desired final shape of the sheet metal, and the sheet is passed through the machine multiple times until it reaches the desired shape. Roll forming machines are used in a wide range of industries, including automotive, construction, and appliance manufacturing, and are known for their high efficiency and precision. They are a key component in the production of many metal products, including roofing panels, steel frames, and automotive parts.
