Shop Mandrel Benders
A mandrel bender is a rotary bending machine used to reduce wrinkles, distortion, and kinks inside the pipe when bending. They can be used to bend tubes at a very tight radius.
A mandrel bender is designed to avoid the issue of wrinkling along the inside of pipes and tubing. The mandrel pipe bender stays in a fixed position as the outer radius of the tube experiences pressure. This pressure causes even badly curled tubes to stretch out into round shapes while avoiding any wrinkles or creases on its surface thanks to that special curved shape of the mandrel tube bender, which helps keep it flush with your desired curves at all times without bending too much inward like other traditional approaches might do when trying for tighter bends where contact between pipe and edges could cause folds if not done just right.
