Manufacture/design of complex mechanical assemblies by Defontaine

Defontaine specialises in the manufacture of complex mechanical assemblies and other types of complex assemblies.

Since 1980, we have developed a mechanised welding process for aerospace industry parts mounted on helicopter turbines. This type of manufacturing involves a wide range of Defontaine’s trades:

Forging and machining for the manufacture, flash-butt welding and rolling of flanges
TIG welding
Boilermaking
Heat treatments
Non-destructive testing
Finish machining: turning and milling-drilling on 3 to 5-axis machining centres
Testing on three-dimensional machine
Assembly of components

All these techniques are fully mastered by our group.

Tailor-made service to meet your technical challenges

The manufacturing process of Defontaine welded assemblies is adapted to the specific features of your product.

Therefore, we can implement different processes to best meet your technical challenges. For example, we offer casing manufacturing using the grinding process: production in an air-conditioned environment, adapted expertise and specific facilities.

Based on our continuous improvement policy we regularly invest to develop our know-how on more complex parts. As a result, we can meet the demanding tolerance requirements for new generations of engines.
