Do you need to know more about our aerospace applications?
We use a large variety of processes to manufacture our flanges, casings and complex mechanical assemblies: forging, welding, shaping, machining, turning or milling.
Defontaine’s flash-butt welding, rolling and forging processes allow to obtain a cross-section close to the profile of the final part in order to save on the volume of material used.
It is also possible to use non-conventional processes such as Electrical Discharge Machining (EDM) or laser cutting.
If necessary and depending on the requirements of our customers, we also use special processes for the aerospace industry which are based on NADCAP certifications or certifications by engine manufacturers.
