High quality custom alloy wheels provider: At present, the performance test standards of wheel hub mainly include: Japanese JWL VIA standard; German TUV standard; American SAE Standard. German TUV standards are the most stringent, which is why European wheel brands are heavy. The following European BBS 19X8.5J cast wheel hub weighs 11.65KG, compared with other cheap cast wheel 19X8.5J hub weight is 10.68kg. Attached is the hub weight reference table, if you buy a particularly light hub , pay attention. Change HUB SAFETY FIRST!! Read even more information on wholesale alloy wheels.
Gravity casting: Alloy aluminum is melted into liquid state and poured into the casting mold, after cooling and solidification, cleaning treatment to get the casting with predetermined shape, size and performance, after molding for mechanical processing (deburring, trimming appearance, polishing) and made. The casting wheels product needs to be molded according to the requirements, and the price is lower for mass production.
Second, the hole distance, screw eye distance and eccentric distance must be suitable for the model. This means that when choosing, you can’t choose the shape you like at will, and you must follow the advice of the technician to consider whether the three distances are suitable. The third is the shape: the complex and dense wheel hub is indeed beautiful and classy, but it is easy to be refused or overcharged when washing the car, because it is too troublesome to wash. The simple wheels are dynamic and clean.
Fuel vehicle: If you use fully synthetic engine oil, a small maintenance every 10,000 kilometers, a single cost of 600 dollar, then 100,000 kilometers need to be maintained 10 times, the total cost is 6,000 dollar, a major maintenance every 30,000 kilometers, a major maintenance Counting 1,000, 100,000 kilometers of maintenance 3 times, the cost is 3,000, so calculated, the total maintenance cost of 100,000 kilometers is 9,000 dollar.
The characteristics of high thermal conductivity of aluminum alloy wheels are extremely beneficial to the heat dissipation effect of the car tires due to high-speed driving, so that they are better than steel under the same conditions. It reduces the possibility of hot tires during long-distance high-speed driving, and significantly improves the safety performance of high-speed driving. It is easier to realize the “tubeless” of modern wheels. For a tubeless wheel, the original rubber inner tube is directly replaced by an aluminum rim. If a “puncture object” such as a nail is inserted into the outer wheel while driving, as long as it is not pulled out, it will not be removed. There will be an accident that the car rolls over due to a sudden flat tire like a tire with a tube. After a tubeless wheel encounters a “puncture object”, it can generally last for at least an hour or even longer, which is particularly important for the safety of cars driving on the highway.
We not only have the traditional low-pressure casting technology, but also have the high strength and light weight manufacturing technology of “low-pressure casting + spinning”. We always maintain various advanced technology advantages in aluminum alloy wheel manufacturing to meet customers’ needs and lead the industry development. The formula has perfect testing equipment, including material testing machine, hardness tester, solid aluminum alloy containing slag quantitative tester, X-ray diffractometer, bending fatigue tester, radial fatigue tester, biaxial fatigue tester, 13° impact tester, 30°/90° impact tester, salt spray test chamber, humidity and heat test chamber, etc., which can carry out the four major testing areas of wheels (dimensional testing, alloy material performance, reliability and safety, coating.
