Rotary draw bending is a process in which a precision mandrel is positioned inside the tube, while a pressure die, wiper die, bend die, and clamp dies surround the outside of the tube. The bend is formed by drawing the material around a rotating bend die. Specifically, the front part of the tube is clamped to the bend die and is drawn around the die as it rotates while the back part is held in place against the rotating bend die by the pressure die.
