Alloy wheels wholesale manufacturer 2023: 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!! Find extra info at https://www.jjjwheel.com/products.
Gravity casting wheels:This is the most primitive processing method for aluminum alloy wheels, which can be formed by pouring high-temperature liquid metal into the mold and cooling it. This method is efficient and low cost, but the uniformity of each part of the manufactured wheel is poor, and the molecular density is relatively low, resulting in low strength, so it is not very suitable for high-strength use of passenger vehicles.
Cast aluminum wheels ultimately need to be processed by CNC machine tools, so no matter the roundness, end direction and radial accuracy of the wheels, they are not comparable to traditional rolled steel rings. The dimensional accuracy of the wheels directly affects the driving performance of the vehicle. Especially for high-speed vehicles, it is more prominent, such as the grip, yaw and stability of the whole vehicle during driving, and braking in case of an accident. The high speed and smooth driving of the car.
Pure electric vehicles are driven by electric motors. Unlike fuel vehicles, the engine combustion is not only loud, but also vibrates greatly. When pure electric vehicles are driving, there is no obvious shaking, and the front of the car does not need an air intake grille. Very quiet in the car. Of course, to drive a pure electric car, you need to master the switch. Many people are prone to motion sickness. Many people are used to driving a fuel car. When you start off with a kick of the switch, the power comes fast, the linearity is very strong, the speed is fast, and the back feeling is full. When braking, the switch is closed, and the power recovery function is added, and the power is lost instantly, and the head-up and nodding movements are more obvious.
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.
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”.
