The stock is referred to as "Technology". Special new "small and medium-sized enterprises, provincial high-tech cultivation enterprises.

First of all, a big advantage of aluminum alloy wheels compared to iron wheels is heat dissipation. First of all, the heat transfer coefficient of aluminum alloy will be about 3 times that of ordinary iron hub. Aluminum alloy wheels quickly transfer heat to the air, which undoubtedly increases the safety factor of the vehicle.

Secondly, the weight of the aluminum alloy wheel will be about 2 kg lighter than the iron wheel, so the 4 aluminum alloy tires will be about 8 kg lighter than the iron tire. To a large extent, it helps the car's handling, cornering or cornering more nimbly. It can also reduce fuel consumption to a certain extent.

Based on the principles of technological innovation and independent research and development, the company has accumulated many years of production experience, and always adheres to the marketing purpose of "customer first, honest management"; the demand is "satisfy all customers", strong research and development capabilities ; The company has a complete and scientific quality management system. The company's integrity, strength and product quality have been recognized by the industry. Taking quality as the core, adhering to the business philosophy of "internationalization, branding, and scale", it is committed to "continuous improvement, pursuit of high-quality products, improvement of service quality, and satisfaction client needs". If you accidentally install inferior car wheels, it will not only bring hidden dangers to your own travel, but also endanger the lives of others.

In recent years, traffic accidents caused by poor quality of wheel hubs have occurred from time to time. It is difficult to distinguish by sight alone, and requires professional instruments to measure, but it can be distinguished by listening to the sound. Only from the appearance, it is difficult to see whether the car wheel is real or not.

Some quality parameters of automobile wheels can only be measured with professional instruments, and the appearance of the wheels does not have obvious anti-counterfeiting marks like RMB. Moreover, due to the application of related metal protection materials, it is more difficult to distinguish, so many car owners have suffered losses. Chang'an original wheel hub repair company was founded in 2011. After more than seven years of development and operation, the company has become a large-scale enterprise in the domestic aluminum alloy wheel industry with product serialization, large-scale production, and brand management.

Many people think that as long as the car hub does not touch the outer metal plate when installing, in fact, when disassembling the wheel, if you look carefully at the structure inside, it is easy to get stuck in many places, especially after the car is started, on rough roads, the shock absorber Instantly compresses. Therefore, make good use of large wheels. You must drive beautifully.

Also pay attention to the width of the rim. Second, the brake calipers snap onto the rim. Because cars these days often use large calipers for safety, a 4lb caliper is much bigger than a can.

Underbiased and poorly designed wheels often get stuck on the brake calipers. Fortunately, it's easy to spot in this case. When the temperature of the car hub is high, it should be allowed to cool naturally before cleaning.

Do not wash it with cold water, otherwise it will damage the aluminum alloy wheel hub, and even deform the brake disc, which will affect the braking effect. In addition, cleaning the aluminum alloy wheel with a high-temperature cleaning agent will cause a chemical reaction on the surface of the car wheel, which will lose its luster and affect the appearance. If the hub of the car is bent, broken or severely corroded, it should be replaced in time.

If damaged car wheels are not replaced, the tires are likely to slip off the car wheels, and the car may even lose control. But if it's just scratches, it's not a big problem. The adhesion of aluminum alloy wheels during the electroplating process is mainly manifested as blistering and peeling. Bubbles refer to the phenomenon of bulges in local areas between coatings. Small bubbles are difficult to pierce with a knife.

Large bubbles are similar to exfoliation after clearing and also exhibit the characteristics of exfoliation. Spalling refers to the phenomenon that the positive film area between the coatings can separate and tear off. Spalling can occur between zinc plating and nickel plating, between semi-gloss nickel and acid copper, and between plated hubs and nickel plating. Different Types have different applications and different solutions. How to repair the original Changan wheel hub is broken? Make color preparation according to the original color of the wheel rim, choose different types of sandpaper for grinding according to different damage degrees, and we need to repaint the car wheel hub.

But before painting, we tried to use waste newspapers to isolate the edge of the wheel hub to prevent the spray paint from splashing on the tires. Put it in the equipment at 100-120℃ to dry for 60 minutes, then grind it again to a matte finish. If it still feels a little hairy, you can continue to smooth it with sandpaper.

Cover the rim with a universal shielding film, wipe the surface of the rim with a degreaser, dry it with equipment, and wipe the surface dust with a dustproof cloth.
