The sheet metal is generally some sheet metal stamping die by hand or to produce plastic deformation, the formation of the desired shape and size, and further to form more complex parts through a
small welding or machining, such as chimney, commonly used in the family iron furnace, and the shell of the car are sheet metal. The main working procedure is cutting, bending, bending, forming,
welding, riveting, etc.
Sheet metal has the advantages of light weight, high strength and conductivity (can be used for electromagnetic shielding), low cost, mass production and good performance characteristics, widely
used in electronics, communications, automotive, medical equipment and other fields, such as computer chassis, mobile phone, MP3, sheet metal is an indispensable part of the. With more and more
extensive application of sheet metal, sheet metal design has become a very important part in the process of product development, mechanical engineers must master the design techniques of metal
parts, makes the design of sheet metal products not only satisfy the function and appearance requirements, but also can make the stamping die has simple manufacture and low cost.
