Throughout the present in the field of electronic and electrical appliances, communications, automotive industry, medical equipment, etc., sheet metal has been widely used and developed, and sheet metal has the characteristics of light weight, high strength, etc., but also has the ability to conduct electricity (able to be used for electromagnetic shielding), low cost, large-scale mass production of good performance, etc., as if in the computer chassis, mobile phones, MP3, sheet metal has become an indispensable part of the components. Sheet metal parts appear frequently in daily life, and sheet metal technology is becoming more and more important and favoured by people.

And as the application fields of sheet metal become more and more extensive, the design of sheet metal parts has become a very important part of the product development process, so mechanical engineers must be skilled in the design of sheet metal parts, in order to make the design of the sheet metal not only to meet the functionality of the product and the appearance of the requirements of the product, but also to make the stamping mould manufacturing is more simple, lower cost. We believe that in the future development trend, sheet metal technology will become more and more popular, more room for development.
