Sheet metal has a light weight, high strength, conductive (able to be used for electromagnetic shielding), low cost, large-scale mass production performance, etc., and is now widely used in the field of electronic and electrical appliances, communications, automotive industry, medical equipment and other fields. For example, in computer chassis, cell phones, MP3, sheet metal is an essential component.
The chassis provides space for the power supply, motherboard, various expansion boards and cards, floppy disk drives, CD-ROM drives, hard disk drives, and other storage devices, and through the chassis internal support, brackets, various screws or cards clips and other connectors will be these spare parts securely fixed inside the chassis to form an intensive whole. Secondly, its solid shell to protect the board, power supply and storage devices, can be anti-pressure, anti-impact, dust, and it can also perform the function of anti-electromagnetic interference, radiation, electromagnetic radiation shielding role
