With the rapid development of information technology, more and more objects that cannot be seen by the naked eye are being used by people, but these objects are not entirely beneficial to the human body. Just like how our computers generate a large amount of electromagnetic radiation during operation, if not prevented, it can cause certain harm to the human body. In addition to the computer host, there are also many instrument devices that emit certain radiation. The chassis that stores these devices becomes a line of defense to shield electromagnetic radiation and protect the health of users. In addition, a well shielded chassis can effectively block external radiation interference, ensuring that the computer is not affected by external radiation. But ordinary computer cases are filled with heat dissipation holes everywhere, and these steel mesh holes used for ventilation cannot effectively block high-frequency electromagnetic waves emitted by some hardware inside the computer case. Nowadays, people's attention to electromagnetic radiation is increasing, and the demand for electromagnetic shielding products will only increase, leading to a growing demand for electromagnetic shielding chassis among consumers in the market.

The working principle of electromagnetic shielding chassis is that the higher the frequency of electromagnetic radiation, the better the conductivity of the metal, and the better the electromagnetic shielding effect. If the surface is non-conductive, it will seriously affect the metal's absorption of electromagnetic radiation. Therefore, most cases that have undergone anodizing treatment are made of aluminum or aluminum alloy materials, which have a very obvious effect on absorbing electromagnetic radiation.
