WebThe pressure die lies tangent to the bend die and serves two functions. First, it provides an appropriate amount of force to bend the tube and maintains constant pressure at the point of tangency. Then, it pushes the straight tube as it travels around the bend with the aid of a pressure die to assist (or pressure die booster).
