A one-stop shop for your projects
Saint Jean Industries is completely proficient in all wheel manufacturing processes, from concept to design validation and delivery to the client.

Process simulation
In liaison with the product design branch and the tooling branch, simulation validates the solutions chosen.

Product validation
Once the product and tooling have been validated, prototypes are validated on our test benches to correlate the results with the simulations.
COBAWHEELS™ technology
With this patented technology, Saint Jean Wheels is pushing back the technical boundaries of traditional wheel manufacturing processes by using better materials combined with the most advanced production techniques.

COBAPRESS™
This proven technology for manufacturing lighter aluminum suspension parts has major advantages: significant design flexibility, improved mechanical properties and very good fatigue resistance.

Flow-forming
This process, commonly used in the manufacture of cast aluminum rims, is applied by Saint Jean Wheels to an extruded tube to reduce the weight of the rim well.

Friction stir welding
This manufacturing process is used in the aeronautical sector and for certain specific automobile applications. Saint Jean Wheels uses it to weld the two parts of the rim, with no metal filler, no matter which alloys are used.
