Forged hub 

First, Maple explains that the manufacturing process for cast and forged wheels is different. Casting is the process of melting metal into a liquid that meets certain requirements and then pouring it into a casting tool. After cooling, solidification and cleaning, the casting basically has a predetermined shape, size and performance. Forging is the use of forging machinery to exert pressure on the metal material, so that it has plastic deformation, so as to forge a certain mechanical properties, shape and size of the forging production and processing method.

The cost between the two wheels is not necessarily the same. Compared with the casting process, the casting process is simple and rough, easy to mass production. Of course, the cost is lower, and the forging process is more complex, so the manufacturing cost is higher. Then there are the forged wheels made of constant tempering. Of course, its molecules are very dense and lined up, resulting in better strength and toughness than the cast, that is, the forged hub is stronger.

In terms of weight, the raw materials of forged wheels are constantly pressed during the production process, so they can withstand higher pressure after forming. At the same time, in the case of similar size and strength, forged wheels are lighter than cast wheels, and most qualified cast wheels are about 20% heavier than forged wheels. However, one disadvantage of forged wheels is that the metal ductility is not good, and the price is more expensive. Mostly suitable for high-end cars.

To sum up, Maple still advocates the preferred forged wheel hub. Such wheels are more secure in details and can get a better experience. If you feel that the forged hub is too expensive, you can choose to spin the hub with the forged embryo. Such wheels are similar to forged wheels in performance, but they are cheaper and more cost-effective.

In addition, when selecting the hub, it is not only necessary to look at the manufacturing type of the hub, but also pay attention to the structural size of the hub. Although oversized wheels can improve the stability of the car, it will be poor in terms of shock absorption and comfort. Of course, follow the advice of professionals and choose the right three-pitch hub.

1, the characteristics are different: through forging can eliminate the cast state of the metal loose, welded holes, etc., so that the density of aluminum is higher, compared with forging and casting will find that the cast finished product will have the feeling of osteoporosis.

2, the advantages are different: the price of casting wheels is low, the production cycle is short. Forged wheel is light weight, good heat dissipation, high strength, not easy to crush after impact, higher safety, strong plasticity, can be customized.

Wheel hub precautions

When the temperature of the wheel is high, it should be cleaned after natural cooling, and must not be cleaned with cold water; Otherwise, the aluminum alloy wheel will be damaged, and even the brake disc will be deformed and affect the braking effect. In addition, cleaning with detergent at high temperature will cause chemical reaction on the surface of the wheel, lose luster, and affect the appearance.

Clean the wheel hub. We can use paint thinner to wipe around the scar to remove dirt. The deepest part of the scratch is difficult to remove the dirt, then you can use a toothpick to clean it thoroughly. When cleaning, in order to prevent the mistake of painting the irrelevant part, it is best to carefully stick the adhesive paper around the scar.
