Other factors involved in the bending process are the wall thickness, tooling and lubricants needed by the pipe and tube bender to best shape the material, and the different ways the tube may be used (tube, pipe wires).
In 1995, Uk-based Unison Ltd developed the first three ‘all-electric’ tube bending machines with 20mm, 40mm and 65mm tube capacity. The very first machine went into service in 1996 and is still in production.Ī tube can be bent in multiple directions and angles. Common simple bends consist of forming elbows, which are 90° bends, and U-bends, which are 180° bends. More complex geometries include multiple two-dimensional (2D) bends and three-dimensional (3D) bends.
