History of the Defontaine Group

Since 1946 the history of Defontaine is very closely tied to a land where the values of loyalty, perseverance and courage are combined with taking pride in a job well done. The group’s growth is based on its mastery of flash butt welding and induction heat treatment technologies, which enable the group to achieve exceptional technical and metallurgical results at very low production costs. The group first developed in the automotive sector, then, from 1967 onwards, in aeronautics and finally in the slewing ring sector.

Defontaine Group serves customers around the world, at the crossroads between our brands and technologies, and offers its customers high-technology mechanical parts and sub-assemblies designed and manufactured using the most advanced quality management methods.
