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 completely beneficial to the human body. Just like the computer in the work will produce a lot of electromagnetic radiation, if not prevented will cause some harm to the human body. In addition to the computer mainframe, there are many instruments and equipment also exists a certain amount of radiation, and the storage of these devices chassis has become a shielding electromagnetic radiation, to protect the health of the user a line of defense, in addition, well-shielded chassis can also effectively block external radiation interference, to ensure that the computer is not affected by external radiation. But ordinary cases are open everywhere with heat sink holes, these small holes for ventilation of steel mesh, is not effective in blocking some hardware inside the chassis issued by high-frequency electromagnetic waves.
Nowadays, people are more and more concerned about electromagnetic radiation, the demand for electromagnetic shielding products will only increase, resulting in the market consumer demand for electromagnetic shielding class chassis is growing. Electromagnetic shielding chassis work on the principle that the higher the frequency of electromagnetic radiation, the better the conductivity of the metal, the better the electromagnetic shielding effect, if the surface is not conductive will seriously affect the metal for electromagnetic radiation absorption. Therefore, the general anodized chassis, the material used is aluminum or aluminum alloy, and this material has a very obvious effect on the absorption of electromagnetic radiation.
Dongguan Jiatong Precision Hardware Manufacturing Co., Ltd. is a professional engaged in all kinds of chassis product development and design, production and sales and service in one of the production-oriented enterprises, the research and development technology owned by the industry has taken the lead in the same industry, product quality and service level has also won many praise. The main products have been widely used in photoelectric equipment, electric power communication, data transmission, instrumentation and other industries.
