The computer-controlled mold gradually levels as the molten aluminium fills it. This method prevents any air bubbles from remaining in the molten aluminium, and have quick filling enable. Once the filling is complete, coolant is circulated through the mold’s water jacket and quickly cools the casting.
The cooling process is minutely computer controlled so that the temperature of the coolant, the rate of cooling, and the degree of cooling are all kept at the level that ensures the strongest castings.
Of course, the superb mechanical properties of aluminium alloy itself are taken into consideration and the best possible combination of metals is used to create the alloy which PDW wheels
are made of.
The combination of all these aspects results in a dense, uniform composition throughout the casting.
