Flow forming uses hydraulic rollers to achieve greater density in the material structure for the rims of our light alloy wheels. The rim well of the over 300 to 350 degree centigrade hot wheel blank is kept in a continuous rotational motion under high pressure and at high temperatures, and subsequently rolled out over a cylinder in one work step. The equipment functions according to the principle of a potter's wheel to remodel the wheel blank. The desired result: a thinner wall thickness of the original rim and therefore a lighter weight wheel. In addition it provides optimally dense material structure and greater material strength.
