What are the automobile production processes

Four major automobile processes: stamping, welding, spraying, general assembly. Among these four processes, the simplest is the stamping process. The stamping process is highly standardized, and a stamping line can produce a variety of models. Now there are also professional independent manufacturers in stamping to provide the necessary stamping parts for automobile manufacturers.

The process of automobile manufacturing mainly includes stamping process, welding process, painting process and general assembly process, commonly known as the "four major processes" of automobiles. Stamping is the first step of all processes, and each workpiece usually takes several processes to complete.It is realized through punching machines and molds.

In automobile manufacturing, those who know a little about cars should know that there are four major processes in car manufacturing, which are stamping, welding, spraying and general assembly.

Welding process: the stamped body panels are partially heated or heated and pressurized at the same time to form a body assembly. Spot welding is the most widely used in automobile body manufacturing. The quality of welding directly affects the strength of the body. Therefore, many manufacturers will emphasize that they are "laser welding" when talking about their body structure.
