Alloy rims wholesale manufacturer in China: 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!! Discover more info on https://www.jjjwheel.com/products.
Flow formed wheel manufacturing process first requires processing the blank with low-pressure casting, then heating the wheel blank, while gradually extruding the final form by rotating the press through the machine. Under the appropriate temperature and pressure of the press, the metal molecules are more dense and fibrous, which can bring higher strength and toughness than low-pressure casting, and the rim after spinning has a thinner cut, so the overall weight of the wheel is reduced. Welcome to inquire about wholesale flow formed wheel price, JWHEEL is the best choice of forged wheels manufacturers.
One is size: don’t blindly increase the hub. Some people increase the wheel hub to improve the performance of the car. Under the condition that the outer diameter of the tire remains unchanged, the large wheel hub is bound to match the wide and flat tire. The lateral swing of the car is small, and the stability is improved. pass by. However, the flatter the tire, the thinner the thickness, the worse the shock absorption performance, and the greater the sacrifice in terms of comfort. In addition, the tires are easily damaged if there are some roadblocks such as stones. Therefore, the cost of blindly increasing the hub cannot be ignored. Generally speaking, it is most appropriate to increase one or two sizes according to the size of the original wheel hub.
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.
One piece forged wheels,Milling and forging,The use of impact or pressure to deform the metal between the upper and lower two against the iron (anvil) to obtain the required block of blanks, blanks after heat treatment and then through the machining center milling and forming, a piece of relatively lighter weight, can achieve the most lightweight dynamic balance better reliability, no hidden gas leakage. The main advantages of steel hubs are simple manufacturing process, relatively low cost and strong resistance to metal fatigue. But the disadvantages are also obvious, such as heavy weight, large inertial resistance, poor heat dissipation and so on.
