تطبيق أجزاء المغنيسيوم thixomolding الطائرة الوسطى للهاتف المحمول

Mobile phones are a tool for people’s daily communication. Mobile phones have appeared many years ago. The most impressive one may be “Big Brother”. This kind of mobile phone is expensive and heavy, and it is inconvenient to go anywhere. Mobile phones are becoming lighter and more functional. Now people pay more and more attention to mobile phones, the weight of mobile phones, the functions of mobile phones and so on.
Now manufacturers use magnesium alloy materials to make mobile phones, and mobile phones become lighter and bring a lot of convenience to people’s travel.

Advantages of thixomolding magnesium parts mobile phone midplane
1. Scale inhibition stability: This is one of the characteristics of magnesium. When the product is removed from the mold, only a small residual casting stress is required, so annealing and stress relief treatments are not required. Under load, this metal can also have good creep resistance. For example, when an am die casting is subjected to a temperature exceeding 120°C for 100 hours, it only needs 0.1%~0.5% of the total elongation.

2. Excellent machinability: Magnesium has better machining and cutting characteristics than aluminum and zinc, making it the easiest metal to machine.

3. High damping performance: Magnesium has excellent hysteretic damping performance, which can absorb vibration and noise, which is important for reducing noise transmission, providing shock resistance and dent resistance.

4 is very important. Lightweight: One pound of magnesium is as strong as 1.8 pounds of aluminum and 2.1 pounds of steel at the same hardness. In short, magnesium can produce parts as messy as aluminum, but only one-third lighter than aluminum. The above features are very important for some modern portable products.

5. High heat dissipation: Magnesium alloys have high heat dissipation properties and are suitable for densely planned electronic products. The thermal conductivity of magnesium alloys is better than that of general structural metals, and it can quickly disperse the heat source. Once a laptop overheats, it can easily destabilize the system.

6. Recyclable: Magnesium alloys can be extracted from seawater, and it is not difficult to obtain raw materials. In addition, magnesium alloy defective products can be fully recovered and refined, and cast as secondary data of AZ91D, AM50 or AM60. Due to the ever-increasing demand for die castings, recycling capabilities are very important. This meets environmental requirements and makes magnesium alloys more attractive than many plastic materials.

The current heat dissipation method is to use a heat pipe to guide the heat source in the engineering plastic shell, add finned heat sinks, or use an electric fan to force convection. Therefore, the thermal conductivity of magnesium-aluminum alloy can reach more than 150 times that of plastic, which is the best choice for advanced notebook computers in the future. Excellent casting performance: Under the condition of maintaining good structure, the wall thickness of magnesium castings can be as small as 0.6mm. This is a wall thickness that plastic products cannot achieve with the same strength. Aluminum alloys can only be compared with magnesium alloys in the range of 1.2~1.5mm. In addition, magnesium alloys do not undergo structural changes after long-term use and temperature rise, and there is no embrittlement problem at low temperatures (below -10 °C).

With the advancement of science and technology, we utilize the green engineering materials of the 21st century, reduce the weight of people’s travel, and reduce the damage rate. If you want to know more, please contact us.
