Application of Metal Precision Die Casting Technology in the Field of Digital Electronics

The electronics industry is one of the most rapidly developing industries today, and it has also become an important application field of magnesium alloy die-casting technology. These portable electronic products mainly focus on the product's light weight, heat dissipation, sturdiness, and electromagnetic wave insulation and aesthetics. Compared with the traditional materials used in these 3C products, the advantages of magnesium alloys are mainly reflected in the following aspects.

●Lightweight and material stiffness

Although magnesium alloys are denser than general engineering plastics, engineering plastics are far less rigid than metal materials. In addition to the high rigidity of metal materials, magnesium alloys are also the lightest material among all structural alloys. Suitable for use in portable products.

●Vibration damping performance and recyclability

The specific damping capacity of magnesium alloy is 10~25 times that of aluminum alloy, which can greatly reduce noise and vibration, which helps to reduce the interference of external vibration on internal precision electronic and optical components. In the environment of high environmental awareness, magnesium alloys have great advantages compared with other materials such as engineering plastics.

●Excellent electromagnetic wave insulation

The high-frequency electromagnetic waves emitted by the chips of portable computers and mobile phones often penetrate the casing, interfere with each other and become noise sources, affecting the quality of communication and computing. In terms of mobile communication, the current quality of mobile phone calls with plastic casings is not high. However, the use of magnesium alloy die-cast casings instead of plastic casings has greatly improved this problem, and at the same time, it can also reduce the damage of electromagnetic waves to the human mind.

●Heat dissipation

Generally, the thermal conductivity of metal is hundreds of times that of plastic. Therefore, when it is used in electronic product casings or components, if the structure and thermal conductivity can be comprehensively designed, the function of heat sink can be used to divert the heat generated by electronic parts. exclude. Considering the heat dissipation requirements of notebook computers and other products, magnesium alloy shells transfer heat quickly and are not easy to get hot, so they are undoubtedly excellent candidates.
