ALLOY WHEEL

Why it made from Aluminum?

1. it’

s more attractive than other metals2. Fraction of the wait, so less energy to rotate it with les fuel

3. Better control ,handling and acceleration

Manufacturing begins with high-grade aluminum alloy

• Containing ninety-seven percent aluminum a furnace

• Heat the furnace to 750 degrees Celsius• They liquefy in 25 min in the furnace

• Then Aluminum pour into mixer with argon gas is inject in toremove the hydrogen so increase its density and less porous

• Adding powder titanium to further strength the alloy• Then a flux is appeared so it must be remove

The wheel mold is made of high-strength steel

It consist of 3 parts

1. The upper which form the inside face

2. Four parts make the wheel edge

3. Lower mold which made the other face

,it is the intricate mold

• This machine is design to fill the mold from the bottom by pressuredinjection

• The injection is from the bottom to reduce the

air bubbles and defects parts

Heat treatment

The casting then goes complex heat treatment

They heat the casting to 500c

Quenching which submerge the casting in water

For 30 sec

Then reheat the wheel to 100c for 9hours

And so on

MACHINING

The rough edges shown is trimmed

The wheel goes CNC lathe machine which remove the edges

And making finishing

INSPECTION

Then they submerge the wheel in water to

If any air bubbles appear this mean defect part because shrinkage takeplace
