Sheet metal parts have the characteristics of light weight, high strength, electrical conductivity (can be used for electromagnetic shielding), low cost, and good mass production performance. They have been widely used in electronics, telecommunications, automotive industry, medical equipment and other fields. Sheet metal parts are an indispensable part in computer cases, mobiles phoness, and MP3s.

With the increasing application of sheet metal, the design of sheet metal parts has become an important part of the product development process. Mechanical engineers must be proficient in designing sheet metal parts so that the designed sheet metal can meet the requirements of the product. Functional and appearance requirements can also make the manufacture of stamping dies simple and low cost.
