Passenger car sheet metal parts are key components of the main structure of the automobile body and some interior parts, and their stamping quality plays a vital role.

[0003] Passenger car metal stampings account for 60% to 70% of the entire automobile manufacturing process, and each car contains an average of 1,200 to 1,500 stampings. These parts are not only used for external covers and internal supports of the car body, but also include key structural reinforcements and other important components. For example, the sheet metal parts inside the car dashboard are used to fix the host or screen.
