Tube swaging machines are used to permanently join pipes together by putting the pipes under high pressure or by pressing them into a die. Unlike traditional metalworking, which relies upon heat, tube swaging machines use cold metalworking processes to form metal. Since swaging is a forming and not a machining process, it results in no wasted metal scrap in the shaping of pipes.
During tube swaging, the tubes are fitted together by increasing or reducing the size of the tube's diameter at the end of the pipe. This shaping is achieved through a repeated hammering motion. The ends of tubes can also be flattened, slotted, notched, flared, flanged, or punched. Rotary swaggers, long die swaggers, and pipe flaring machines are some of the different designs of tube swaging machines. Swaging machines are used on tubes made from a variety of metal materials, including steel, aluminum, brass, copper, titanium, and stainless steel. The tubes made by swaging machines are used in the aerospace, automotive, construction, marine, medical, and military industries.
