1 Answers
The four major processes in automobile manufacturing are described in detail as follows: 1. Stamping: Sheet metal parts are formed according to design requirements using molds. Stamping forming process plays an important role in automobile body manufacturing, especially for large body panels which often have complex shapes, large structural dimensions, some with spatial curved surfaces, and high surface quality requirements. 2. Welding: Various sheet metal parts are welded together to form the car body-in-white according to design requirements. Welding process depends on factors such as welding methods, and operators need to determine the appropriate approach based on the material, grade, chemical composition of the workpiece, structural type, and welding performance requirements. 3. Painting: The body-in-white undergoes pretreatment, primer coating, and top coating. Automobile painting process can generally be divided into two main parts: one is metal surface treatment before painting (also called pretreatment technology), and the other is the painting construction process. 4. Final Assembly: All interior and exterior components including the engine are assembled onto the car body, eventually forming a complete vehicle. After passing various quality inspections, the vehicle is considered finished.
