Abstract
A method of enhancing the bending process of a stabilizer bar by locally pre-heating the stabilizer bar immediately prior to formation. By pre-heating the stabilizer bar, the stress in the stabilizer bar is relieved at the bending areas. This allows larger bars to be formed which would otherwise be outside of machine parameters. In the disclosed embodiments, the stabilizer bar is locally heated by induction coils or resistance heating at the bend areas.
