Wheels may be manufactured in a variety of ways. Two of the most popular manufacturing processes are “cast” and “forged” wheels. Each type is manufactured in a different manner and associated with different advantages and disadvantages.
Process of Manufacturing Cast Wheels
The casting process involves pouring or using a vacuum to insert molten aluminum into a mold that is formed into the shape of the wheel in different dimensions. Positive pressure is used to move the aluminum alloys into the mold more quickly and to achieve a product that has a greater density than a gravity cast wheel. It’s allowed to cool. Then, minor modifications are made into the wheel, such as drilling and trimming. This manufacturing process is preferred over others because it’s fast and inexpensive. It’s also less complicated than other processes.
Advantages of Cast Wheels
Cast wheels offer a good value for a tire while also maintaining strength and a lighter weight. They are easier to make, so the cost savings are often passed on to the buyer.
Disadvantages of Cast Wheels
Allowing the molten aluminum to solidify can result in inconsistencies that can cause cracking and oxidation in the wheel. The wheel’s structural integrity can be reduced through this manufacturing process. The wheels may be made heavier to compensate for this potential problem.
Process of Manufacturing Forged Wheels
Forged wheels begin as a solid piece of metal that is then exposed to heat and intense pressure that compresses the material. This material is forged into different dimensions based on the wheel design.
In contrast to casting, a forged wheel begins as a solid piece of metal referred to as a “billet.” This billet is then subjected to heat and intense pressure, which compresses the material to form a raw forging. These raw forgings are “forged” into different profiles to allow for the creation of different wheel designs.
Advantages of Forged Wheels
Forged wheels are less porous than cast wheels because of the forging process. The forging process makes these wheels stronger, more durable and more resistant to corrosion and oxidation. Additionally, the wheel’s structural integrity is not compromised. Forged wheels tend to have greater overall vehicle performance and enhanced fuel efficiency.
Disadvantages of Forged Wheels
Forging is a more time-consuming and precise process. This makes the process more expensive, making the wheels more expensive to consumers. Cast wheels can be quality wheels, so some consumers may not be willing to pay the higher price point demanded of forged wheels. However, forged ones offer an incomparable value to consumers.
