Sheet metal with light weight, high strength, conductive (can be used to electromagnetic shielding), the cost is low, the large-scale mass production performance is good wait for a characteristic, is currently in the electronic appliances, communication, automobile industry, medical equipment and other areas to be a wide range of applications, such as in the computer case, mobile phones, MP3, sheet metal is an indispensable component.

With the application of sheet metal is more and more extensive, sheet metal parts design into the product development process is the important part, mechanical engineer must master the pieces of metal design techniques, which makes the design not only meet the function of sheet metal products and appearance etc request, and can make stamping mould manufacturing is simple, the cost is low.
