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: Rays Engineering Manufacturing Process.
The forging process for a Rays Wheel consists of seven steps:
- Hot Forging - Takes a billet and creates metal lines through volume distribution with a hot press.
- RM Forging - Forging method exclusively developed Rays Engineering. Finishing of designed parts on the wheel is completed during this process.
- Cold Spinning - Width of wheel is constructed during this process with a high-speed spinning machine.
- Heat Treatment - Wheel is quickly heated then immediately cooled down with a solution to form a strong structure for the wheel.
- Machine Work - Special cutting device used to improve roundness of the wheel.
- Shot Blast - This process smooths the surface of the wheel to prepare of aesthetic finishing.
- Surface Finishing - Various chemicals are used to prevent corrosion and protect the surface of the wheel
Types of Forged Wheels
- Forged 1 Piece Magnesium
- Forged 1 Piece Aluminum
- Forged (Seamless) Rim 2 Piece Wheel Aluminum
The casting process for a Rays Wheel consists of four steps:
- Fusion - Aluminum metal is heated up into molten liquid.
- Molten Metal Treating - Process of removing impurities from molten aluminum. Molten aluminum with no impurities are moved into a holding furnace.
- Casting - Molten aluminum is poured into a die to form the wheel.
- Machine Work - Various chemicals are used to prevent corrosion and protect the surface of the wheel
Types of Cast Wheels
- Cast 1 Piece Aluminum
- RCF (Rays Cast Flow Forming) Casting 1 Piece Aluminum
- Volk Racing - Flagship forged sport wheels brand name of Rays Engineering.
