What are the four major processes in automobile manufacturing?

[SanMakayla]

The four major processes in automobile manufacturing are stamping, welding, painting, and assembly. Stamping: A forming processing method that uses presses and molds to apply external force to sheets, strips, pipes, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces (stamped parts) of the desired shape and size. Stamping and forging both belong to plastic processing (or pressure processing), collectively known as forging and stamping. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. Welding: Known as the mechanical tailor, it is responsible for welding the stamped workpieces together and is widely used in manufacturing. In the automobile manufacturing process, the four steps are: stamping - welding - painting - assembly, where the automation and flexibility of welding determine its development prospects and future. Painting: An important part of the surface manufacturing process for construction machinery products. The quality of rust-proof and corrosion-proof painting is one of the important aspects of the overall product quality. The appearance quality of the product not only reflects its protective and decorative properties but also constitutes an important factor in the product's value. Assembly: The process of assembling parts into the complete product.
