Ultra light aluminum wheels

Areas of expertise

Saint Jean Wheels can provide comprehensive engineering support, from the design of parts to mass production. All of the studies and developments can be conducted in-house in liaison with our various branches, ensuring that the response is adapted to your requirement.

Product development

Our research department develops wheels in accordance with your specifications. The process includes iterations with the calculation and simulation branches to achieve the targets set in terms of mass and mechanical strength improvements.

Our development tools: Catia V5, Altair, HyperWorks.

Casting and forging simulation

All developments go through casting and forging simulation as part of the COBAPRESS™ process to determine the feasibility of the parts designed and ensure the highest possible level of quality.

Advantages of casting simulation:

  • Reduces the development time for a part.
  • Prevents numerous tooling modifications by producing defect-free parts from the first casting.
  • Determines the process parameters without tests.

Advantages of forging simulation:

  • Reduces the development time for a part.
  • Prevents numerous tooling modifications by producing defect-free parts.
  • Defines the type of press to use.
  • Optimizes the lifespan of forging tooling.

Our simulation tools: MAGMA, SIMUFACT.

Test

Final validation of a rim involves a battery of tests correlated with digital models. Following this first in-house validation, the rim is certified by a renowned independent body:

  • Fatigue on bending bench
  • Radial fatigue
  • Energy absorption
  • ISO 7141 impact
  • Radial impact
  • ZWARP (bi-axial)
  • Mechanical properties
  • Micrograph
  • Corrosion test (cass test).
