What are the advantages of forged wheels than cast wheels?

Do you really know the value of forged wheels?

What is casting?

That is, after the metal is smelted into a liquid, it is poured into the model, and after it has cooled and solidified, the casting is taken out of the model, and the taken-out casting is called a blank and needs to be processed. The cast materials are mostly metals (such as iron, copper, aluminum, etc.), and the materials of the molds are mainly divided into three types: sand, metal and ceramics; they are often used to manufacture mechanical parts with complex shapes or under static load and compressive stress.

The price of cast wheels is more affordable.

·Advantages: low mold cost and high efficiency in manufacturing complex shaped castings.

·Disadvantages: Relative to forging, it is easy to have bubbles and the strength of castings is low.

What is forging?

It is to heat the metal blank to the ideal working temperature and apply external force to it to change its shape, density, mechanical properties and grain structure. According to the temperature range of the workpiece during processing, it can be divided into three types: hot forging, warm forging and cold forging. It is often used to manufacture mechanical parts that bear relatively large dynamic loads.

When modifying a vehicle, forging wheels often cost more!

·Advantages: Reduce air bubbles and change grain structure due to pressurization, and forgings have higher strength.

·Disadvantages: Due to the high mold cost, it is not suitable for small-scale production, the manufacturing process is complicated, and the shape complexity is limited.

Why is wheel forging better than casting?

Because forgings have higher strength and density and can withstand higher stresses, compared with rigid cast wheels, forged wheels are lighter in weight. The advantages of lightweight wheels are as follows:

·Reduce the energy consumption of the engine transmitted to the rear wheels, thereby improving the acceleration performance

·Reduce unsprung mass, better suspension response, improved road quality, and improved braking performance

·Because the wheel hub is lightweight and uniform in mass distribution, the wheel set gyro effect is reduced and the vehicle handling performance is improved
