Ironworkers and combination machines have multiple stations to perform different metal-forming functions with one machine. Ironworkers generate high-pressure hydraulic force for forming operations on thick plate metal, angles, and bars. Dies and add-ons attach to ironworkers to improve or expand their functionality by replacing worn dies, changing die shapes or sizes, or adding stations and other attachments. Combination machines (also known as manual ironworkers) perform different forming functions on sheet metal.
