Production process of Used Car subframe

As an important part of the chassis of Used Fuel Car, the subframe plays a vital role in the handling, comfort and safety of the vehicle. Its production process involves multiple complex processes and strict quality control, and is an indispensable key link in the manufacture of Used Fuel Car.

The production of Used Car subframes usually starts with the selection of raw materials. Excellent steel is the main material for manufacturing subframes. It has high strength, good toughness and fatigue resistance, and can meet the requirements of subframes to withstand various complex stresses during vehicle driving. The raw materials are processed by cutting, stamping and other preliminary processing to make the sheets or pipes into blanks for various parts of the subframe.

In the component forming stage, common processes are welding and forging. The welding process can connect multiple parts into a whole. Through automated welding equipment, such as robot arc welding, the stability and consistency of welding quality can be guaranteed, so that the weld strength meets the design requirements. Forging is suitable for some parts with high strength requirements. Forging can improve the internal structure of the metal and improve its mechanical properties.

After Used Car parts are formed, they still need to undergo mechanical processing, including drilling, milling, grinding and other processes, to ensure the accuracy of each installation hole and mating surface, and to ensure that the subframe can be accurately connected with other components when the vehicle is assembled.
