Custom Rim 411 - part 6 - More on Cast WheelsCasting is the most common method of producing custom wheels. The process basically involves getting molten aluminum inside of a mold to form a wheel. Gravity casting is the most basic process of pouring molten aluminum into a mold utilizing gravity to fill the mold. Since this process relys on gravity to fill the mold it is not as densely packed and has small air pockets that could create stress cracks. Additionally gravity cast custom wheels will have a higher weight. Low Pressure casting uses positive pressure to move the molten aluminum into the mold quicker to produce a wheel that is more dense and has improved mechanical properties. Tilt Die Casting is a fairly new process of casting wheels. The mold is tilted to 90 degrees and then the mold is filled quickly and moved back to it's original position. This process reduced the amount of bubles and air pockets. Due to the high cost few manfacturers use this process.
