Flow forming is one of the most advanced manufacturing technologies to be introduced to the alloy wheel industry. This process involves placing a low pressure and heat treated casting unique to Flow Forming Technology onto a flow forming mould. Extensive heat and pressure are applied to the barrel which draws and compresses the aluminium to form the finished shape, this, in turn, alters the mechanical properties of the metal resulting in forged like tensile strength. Advantages over a conventional cast wheel are the wheel is thinner, stronger and significantly lighter, being comparable to a more expensive forged aluminium wheel.
