A method of bending in which the ductility of the tubing material is increased by heating it either before placement on the machine or in-process. Usually in-process heating of the material is done indirectly; heating elements are fixtured in the tools and so the material is heated by conduction through the tools. Few bending applications benefit from hot bending; even titanium is bent cold today more often than hot.

A complete guide to the principles of the 4-Step set-up for tube-bending tools
This is a printable handbook showing how to implement in four standardized steps the “forward mandrel” set-up for rotary-draw tube-bending machines and establish process control over the so-called black art. The procedure is based upon the guiding principle that the tools make the bend and takes advantage of the inserted design of modern mandrel tooling.
