In baking paint and electroplating, the circuit hub is a better material. Compared with the painted wheel hub, the color of the electroplated wheel hub is more vivid and beautiful.

Electroplated wheels can be divided into three types: silver plating, water electroplating and pure electroplating. The color retention time of silver electroplating wheel and water electroplating wheel is short, so the market price is relatively cheap, ranging from 300 yuan to 500 yuan. Pure electroplated wheels have longer color retention time and better quality. As the saying goes, the market price of pure electroplated wheels is correspondingly higher, around 800 yuan and 900 yuan.

Although there are many kinds of vehicles, their structures are similar. This should be said to be the credit of standardization and the need of large-scale production line. With the development of society, the progress of science and technology and the change of demand, the appearance of railway vehicles has also begun to change, especially the passenger cars are no longer the same old faces. However, their basic structure has not changed obviously, but the specific parts have more scientific and advanced structural design.

Generally speaking, the basic structure of a vehicle consists of five parts: body, underframe, running gear, coupler buffer device and braking device.

The car body is the part of the vehicle carrying goods or passengers, and it is also the basis for installing and connecting other parts of the vehicle. The bodies of early vehicles were mostly wooden structures, supplemented by steel plates and bow bars. Modern automobile body is mainly steel structure or light metal structure.
