To produce more complex multi-bend components, for small diameter tube where it is possible to bend it manually, hand bending jigs use compression bending. The next step up is a simple manual pipe bending tool, a type often used by plumbers for copper tube. Compression tube bendingĬompression tube bending, is akin to bending a copper pipe around your knee you are holding one end of the tube stationary and forming the tube into shape around the former (in this case your knee). There are fundamentally three approaches known respectively as compression bending, draw bending and roll bending. In order to understand the optimum design characteristics for tube bending and manipulation manufacture it is important to appreciate the different methods of tube bending.
