1. Sheet metal has the characteristics of light weight, high strength, conductive (can be used for electromagnetic shielding), low cost, large-scale mass production performance and so on. At present, sheet metal has been widely used in the fields of electronic appliances, communication, automobile industry, medical devices and so on. For example, in computer case, mobile phone, MP3, sheet metal is an essential part.
2. With the application of sheet metal more and more widely, the design of sheet metal parts has become a very important part in the process of product development. Mechanical engineers must master the design skills of sheet metal parts, so that the designed sheet metal can not only meet the requirements of product function and appearance, but also make the stamping die manufacturing simple and low cost.
3. Sheet metal is sometimes used as trigger gold. The word comes from English sheet metal. Generally, some sheet metal is pressed by hand or die to produce plastic deformation, forming the desired shape and size, and further forming more complex parts by welding or a small amount of machining, such as the chimney, tin furnace, and car shell are sheet metal parts.
4. Modern sheet metal technology includes: filament power winding, laser cutting, heavy processing, metal bonding, metal drawing, plasma cutting, precision welding, roll forming, metal plate bending forming, die forging, water jet cutting, precision welding, etc.
