Flow forming technology is one of the most advanced manufacturing technologies to enter the wheel industry. Flow Forming Technology involves the application of pressure to the inner barrel of the wheel, while spinning and after it has been casted. This process stretches and compresses the aluminum, which increases tensile strength. In this respect the process shares similar properties to those found in the forging process. The final product is lighter, stronger, has increased elongation, and a much greater shock resistance as well as the ability to increase load capacity over a traditional cast wheel (of the same design).
Flow Forming Technology has a great number of benefits. Konig has been producing Flow Formed wheels since 2010 and is always improving on the process and efficiency to improve the end product. Below are some visual charts for you to see the drastic benefits as it relates to elongation and tensile strength vs a regular cast wheel. The numbers used are approximate and only for general comparison. These are based off of wheels similar in styling, size, width and other specification. One wheel was a conventional cast constructed wheel and the other is developed using Flow Forming Technology.
