Sheet metal has the characteristics of light weight, high strength, conductivity, low cost, and good mass production performance. Currently, it has been widely used in fields such as electronic appliances, communication, automotive industry, medical equipment, etc. For example, in computer cases, mobile phones, MP3 players, sheet metal is an essential component.

With the increasingly widespread application of sheet metal, the design of sheet metal parts has become an important part of the product development process. Mechanical engineers must proficiently master the design skills of sheet metal parts, so that the designed sheet metal not only meets the functional and appearance requirements of the product, but also makes the manufacturing of stamping molds simple and cost-effective.
