We custom machine internal bending mandrels for customers that bend tube to meet specific needs. The mandrels can be designed to bend and size, shape, or thickness of tubing an insure a quality, consistent bend free from wrinkles or tube collapses. Mandrels are typically machined out of an aluminum bronze alloy that is softer than the material being bent to make certain the tooling wears down before damage can be done to the bending machine.
