Engineering

We're putting all our efforts to ensure you'll get the highest quality and the best performances buying our forged or cast rims. Our know-how is based on 50 years of experience and on a constant feedback between our customers and our engineers.

Wheel centres

Cast centres

Cast centres come from a French aluminium foundry and are used for our historic wheels. We get them raw and have to machine them following the specifications of each order, sand and paint them with great care so that each wheel gets a stunning and unique look.

Forged centres

Our forged wheels are machined in raw forged aluminium blocks. Such forging process is among other used in high-quality mecanic parts in the aviation and space industry. Under a gigantic pressure of up to 8000 tons, the aluminium bloc is pre-heated to 500°C and pre-formed into a raw wheel centre. The alloy we use for our rims is the 6082 T6, which combines a high resistance degree and lightweight. Hence, a forged wheel is 20% lighter than a cast wheel. Forged wheels have the highest material density possible, which allows the wheel centre to be thinner.

The blocks are then machined by our technicians according to your needs and the design you wish. For example, we can adjust the design to fit big brake calipers or to perfectly fill the space within your wheel arches.

Lips and barrels

The material used for our lips and barrels is aluminium or stainless steel. We get our aluminium delivered in the form of 6 or 8mm thick discs, and ou stainless steel in the form of 2mm discs. Their quality is tested at each delivery. The raw materials are chosen because of their capacity to be spun precisely, while keeping great robustness and lightweight once mounted on your vehicle. The diversity of sizes we have on our lips and barrels allows for adjusting the width of your wheel with half-inch accuracy.

Metal spinning

Le repoussage des métaux est une technique ancienne et simple dans son principe, mais qui requiert un savoir-faire important. Un disque brut et plat est positionné sur un mandrin de forme qui donne le profil final à obtenir. Le tout est alors mis en rotation à une vitesse adaptée au matériau à déformer.

Des galets viennent repousser la matière selon la forme du mandrin. Lors de cette étape, la matière est extrêmement comprimée, rendant possible une résistance maximale pour un poids minimal. Des outils de coupe viennent ensuite effectuer les finitions pour une rotondité parfaite.

Ce procédé est également appelé fluotournage et a longtemps été utilisé pour la production de jantes de Formule 1 (notamment par la marque OZ).

Turning

Le tournage est la seconde étape de fabrication des voiles de jante. Les élément issus du repoussage sont ensuite mis sur un tour à métaux sur lequel nos techniciens viennent manuellement effectuer des finitions d’une haute précision.

Piercing

Cette étape consiste à percer de façon la plus précise possible, tous les trous qui vont permettre l’assemblage des voiles à la partie centrale. Nous effectuons cette opération sur des machines à commande numérique, garantissant ainsi une précision absolue, et nous donnant la possibilité d’adapter les voiles à toutes les demandes.

Polishing

Polishing is made in two steps. A first polish eliminates any imperfection and gives a smooth aspect to the metal. The second polish is a special process that gives the metal a shiny look.

Finallly, each serie is finely controlled to ensure that none of our products has lateral or radial run-out.

Before being send out to our customers, each wheel is checked to ensure it has perfect roundness and that its finish is flawless.
