Production Process of Motorcycle wheel
We are the motorcycle wheels manufacturer, production motorcycle wheels since 2009.
We can supply different type aluminum alloy wheels, like forged wheels or casting wheels.
There are two types of rim manufacturing: forging and casting.
The forged wheel is made of high-strength forging. Under the same size and the same style, the forged wheel has lighter weight, better heat dissipation, higher strength, less smashing after impact, higher safety, strong plasticity, and can be customized.
The casting wheels is divided into gravity casting and low pressure casting. Gravity casting: The aluminum ingot is converted into aluminum water, which is mainly poured into the mold cavity by the gravity of the aluminum water itself. The pressure in the flow comes from the weight of the aluminum water itself, but gravity casting belongs to the most primitive casting hand, technology The content is low, so most of them use labor, and the process level is difficult to guarantee.
Low-pressure casting: The aluminum ingot is converted into aluminum water, which is directly extruded into the rim model through a conveying pipe, and is pressed down and pressed for 30 minutes. Low-pressure casting is the process in which aluminum water enters the mold under pressure and the aluminum liquid solidifies and crystallizes under pressure. The whole process is mechanized, so the process level is very stable. In terms of production cost, the cost of low-pressure casting is greater than that of gravity casting. However, due to the need for mass production, automobile manufacturers now specify the use of low-pressure casting products to ensure product quality.
The performance of the motorcycle wheel is the key to ensuring safe driving of the motorcycle. Motorcycle wheels will withstand a variety of alternating loads during high-speed driving. If the line runs at a constant speed, the ground will produce radial load on the wheel; when the motorcycle turns, the vehicle will generate centrifugal force, and the wheel must withstand the bending moment caused by centrifugal force; during the start, brake, acceleration and deceleration of the motorcycle, the wheel needs to be Torsion torque is applied; when the motorcycle crosses an obstacle, the wheel is subjected to an impact load. Therefore, all motorcycle wheels must be tested before leaving the factory. For example: 1. Rotational bending fatigue performance test, 2. Radial load fatigue performance test, 3. Torsional fatigue performance test, 4. Radial impact test.
