Only Saint Jean Wheels is completely proficient in this hybrid technology, which makes no compromise on design versus weight and robustness.

Do you want to make mass improvements and explore every possible technological avenue to reduce the weight of your future vehicles?

Technological positioning

Product design

Our research department can design and optimize all types of parts.

Process simulation

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

Tooling development

Our research department designs the tooling for each project.

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.
