Mandrel Tubing Bender

The machines known as Mandrel benders (MB for short) are used to bend tubing or piping to a tight radius with minimal deformation in the shape of the tube. A Mandrel Bender is usually required in situations where bending thin walled tubing to a radius much tighter than the material can bend without becomming deformed. The word "mandrel" refers to the part of the tooling set up which is inserted into the tube and remains inside the tube or pipe during the entirety of the bending process. The mandrel aids in supporting the shape of the tube wall when bending. The most common used for a mandrel bender is when bending tubing used for automotive or motorcycle exhaust pipes.
