COBAWHEELS

Hybrid Technology

COBAWHEELS technology is a patented technology combining 3 processes: COBAPRESS™ for the front face, flow forming for the rim bed and friction welding to join the 2 components.  

This technology reaches the limits of lightweighting for an aluminum rim without compromising the design that gives it its character.

Technologie Cobawheels

The advantages of Technology

  • The flow-formed rim bed can reach low thicknesses with high mechanical properties extrusion alloys.
  • The front face made of COBAPRESS™ benefits from design flexibility. It also offers high properties that will promote the fatigue life of the rim.
  • The assembly of the two parts thanks to the FSW cold friction stir welding process, allows a perfect cohesion of the materials used.
  • We use the minimum amount of material in the manufacturing process. We use fewer tools to carry out all the operations.

The cobawheels' processes

COBAPRESS™

This process offers great design flexibility, improved mechanical characteristics, and very good fatigue resistance

Friction welding

Used to weld the two parts of the rim, without adding metal, whatever the alloys used

Flow forming

A process commonly used in the manufacture of cast aluminum rims, Saint Jean Wheels applies it to an extruded tube to lighten the rim bed.
