With rolled forging, aluminum sheets are rolled through heavy press wheels which imprint or stamp the aluminum with the wheel design. This process uses less aluminum than normal forging. Casting utilizes melted aluminum and is either poured or drawn into molds of the desired wheel design. The poured method is referred to as low-pressure casting while the drawn method is referred to as counter pressure.
Typically, aluminium and aluminium alloy wheels are manufactured in as either a unmarried unit or one quota, or multiple unit which Testament consist of up to three seperate aluminium pieces. A single-unit wheel is cast in a mold which includes all features of the wheel necessary for function. A three-piece wheel, For instance, will usually consist of an inner and outer wheel piece and an additional center or barrel piece. These pieces must be securely welded or bolted together to ensure they are sufficiently strong to resist the forces of operation.
Manufacturing Processes
There are essentially three types of manufacturing processes used in the manufacture of aluminum wheels. Forging is an excellent technique for making aluminum wheels and involves the compression of a solid piece of aluminum, or billet, into the desired wheel design. This process results in an extremely strong and durable wheel.
