aluminum casting is an important part of the automobile industry, including electric pedal, cylinder, water tank, oil pump, transmission, chassis, hub and so on. The content of aluminum in the earth’s crust is relatively rich, and the finished product can be obtained through the process of casting and casting of aluminum.

    aluminum alloy hub has many characteristics which can not be compared with many steel wheels, so the aluminum alloy hub has been widely used in cars, motorcycles and other vehicles. By 2002, the loading rate of China’s car aluminum alloy wheels has reached nearly 45%. The development of low pressure casting technology is greatly promoted because of the high quality requirements of the automobile hub and its structure suitable for low pressure casting and large demand. At present, low pressure casting has become the main process of aluminum alloy wheel production, and most of the domestic aluminum alloy wheel manufacturing enterprises use this process.

    as the small editor said, the aluminum alloy wheel hub of the automobile is used for low pressure casting, and the low pressure cast aluminum can achieve high mechanization and automation. It can not only improve the productivity (10~15 type /h), but also reduce the human factors which are not conducive to the production process, increase the rate of finished products, and greatly reduce the labor intensity of the workers. However, the quality of low pressure casting parts is influenced by such factors as process plan, process parameters, die structure and manual operation, and the mutual influence between them. The improper design or improper operation of any link may lead to the defects of the low pressure casting parts. Hangzhou Hongcheng Pml Precision Mechanism Ltd is a low pressure casting aluminum manufacturer, also has aluminum foundry casting, gravity casting technology, I wish you all business prosperity.
