Wheel construction

Rays Engineering wheels are manufactured through two different processes: forging and casting. After each wheel is manufactured, the wheel goes through strenuous inspection before being packaged and shipped out. The following is a video showing each manufacturing process of a Rays Engineering wheel: .

Forging

The forging process for a Rays Wheel consists of seven steps:
  1. Hot Forging – Takes a billet and creates metal lines through volume distribution with a hot press.
  2. RM Forging – Forging method exclusively developed Rays Engineering. Finishing of designed parts on the wheel is completed during this process.
  3. Cold Spinning – Width of wheel is constructed during this process with a high-speed spinning machine.
  4. Heat Treatment – Wheel is quickly heated then immediately cooled down with a solution to form a strong structure for the wheel.
  5. Machine Work – Special cutting device used to improve roundness of the wheel.
  6. Shot Blast – This process smooths the surface of the wheel to prepare of aesthetic finishing.
  7. Surface Finishing – Various chemicals are used to prevent corrosion and protect the surface of the wheel

    Types of forged wheels

The casting process for a Rays Wheel consists of four steps:
  1. Fusion – Aluminum metal is heated up into molten liquid.
  2. Molten Metal Treating – Process of removing impurities from molten aluminum. Molten aluminum with no impurities are moved into a holding furnace.
  3. Casting – Molten aluminum is poured into a die to form the wheel.
  4. Machine Work – Various chemicals are used to prevent corrosion and protect the surface of the wheel
