Description
* **Prototyping:** Individual prototypes are created from sketches and draft designs, with each wheel being hand-finished.
* **Foundry:** Liquid aluminum is poured into a mold using a low-pressure casting process, then cooled in a water bath.
* **Quality Control:** All rims undergo X-ray inspection to ensure precision and functionality.
* **Flow Forming and Thermal Treatment:** The rim well is rolled out under high pressure, compacting the material. Thermal treatment at over 500 degrees Celsius enhances strength.
* **Precision Machining:** Highly specialized CNC machines process each wheel to its final dimensions.
* **Lacquer Finish:** A perfect shine, beautiful surface finish, and long-lasting quality are achieved through advanced painting and surface treatments.
