This process minimizes the bubbling effect aluminum and Reduces air pockets.
In tilt casting, the metal is poured into a holding cup while the mold is in its horizontal position. Then, with a preset cycle time, the casting machine raises to a vertical position, allowing the metal to enter the die cavity at a slow, continuous pour rate. The tilt-pour method is a good choice for general casting purposes because of it’s feed/gate flexibility which allows for a wide variety of casting shapes.
SPIN FORMING PROCESS
Stretching results in an improved grain structure of the aluminum, which makes for a stronger, thinner, and lighter forged-like rim barrel.
The final product is more durable on impact end enhances overall vehicle performance.
STEP1 Heat end coating is applied to the spin-forming drum. Cast wheel is mounted on the drum and ready to be formed.
STEP2 Pressure is applied to the rim barrel. Specially designated hydraulic rollers are used to stretch the wheel by applying pressure to the rim barrel.
STEP3 The wheels properties are compressed and stretched to achieve the desired width.
