What processes are involved in shaping car panels?

Shaping car panels primarily involves processes that create the desired form and structure of the metal used in manufacturing. Pressing and folding are two critical techniques used in this process. Pressing involves using a stamping machine to form sheet metal into specific shapes and contours required for various car body components. This method not only allows for precision in shaping but also optimizes the use of material, resulting in panels that are both lightweight and strong.

Folding is a complementary process where edges of the panel are bent to create stiffening features, such as flanges and seams, which improve the overall structural integrity of the car panel. Both processes are essential in achieving the automotive industry's rigorous standards for quality and functionality.

In contrast, the other processes listed, while important in manufacturing, do not align as closely with the specific requirements for shaping car panels. Welding and soldering are primarily joining methods, milling and drilling are more suited for machining operations, and cutting and stitching do not directly relate to the forming of panel shapes in automotive applications.
