Analysis of the 4 core advantages: How JARKEL Casting reshapes the customization standards of magnesium alloy AR glasses frames

With the rapid development of AR (augmented reality) technology, users have increasing demands for wearing comfort, heat dissipation performance and lightweight of equipment. Traditional materials such as aluminum alloy and engineering plastics can no longer meet the stringent requirements of high-end AR glasses. In this context, JARKEL Casting has become the preferred partner of global AR glasses manufacturers with its innovative application and precision processing technology of magnesium alloy materials. This article will deeply analyze the 5 core advantages of magnesium alloy frames and show how JARKEL Casting promotes industry innovation through customized solutions.

1. Why has magnesium alloy become the "golden material" for AR glasses frames?
1. Ultra-lightweight and high strength
The density of magnesium-lithium alloy is only 1.35-1.65 g/cm³, which is 1/3 lighter than aluminum alloy, but its specific strength (strength/weight ratio) is significantly better than aluminum alloy and engineering plastics. For example, Thunderbird X2 AR glasses use a magnesium-lithium alloy frame, weighing only 98 grams, realizing a "wireless integration" design, which greatly improves wearing comfort.

2. Excellent heat dissipation performance
The thermal conductivity of magnesium alloy is 300-400 times that of plastic, which can quickly export the heat generated by the chip inside the AR glasses to avoid performance reduction or component damage caused by overheating. The magnesium alloy frame of Meta Orion AR glasses uses an efficient heat dissipation design to ensure long-term operation stability.

3. Shock absorption and electromagnetic shielding
Magnesium alloy has a high internal friction coefficient, which can absorb the vibration energy of the equipment and reduce the image blur problem caused by the jitter of the optical module. At the same time, its electromagnetic shielding performance can reduce signal interference and improve the communication stability of AR glasses.

4. Complex structure molding capability
JARKEL Casting uses a semi-solid injection molding process, which combines the efficiency of die casting with the precision of forging. This process reduces mold thermal stress and extends life by low-temperature filling (100°C lower than traditional die casting); at the same time, it achieves thin-wall (less than 0.5mm) forming and high dimensional accuracy to meet the needs of AR glasses for complex geometric structures.

2. Customized solutions of JARKEL Casting
1. Full-process material and process support
- Material optimization: Provide customized magnesium-lithium alloys containing 5%-16% lithium, balance lightweight and mechanical properties, suitable for key components such as frames, temples, and shafts.
- Precision manufacturing: Integrate semi-solid injection molding, CNC processing and die-casting technology to achieve rapid delivery from prototype design to mass production. For example, after the JARKEL process was adopted for the shell of Goertek AR glasses, the scrap rate was reduced by 60% and the material utilization rate was increased to 95%.

2. Integrated design of heat dissipation and structure
For the high-power chips of AR glasses, JARKEL has developed a bionic heat dissipation structure. Through the internal micro-channel design of the magnesium alloy frame and the surface nano-coating technology, the heat dissipation efficiency is increased by 40%. This solution has been applied to the Xiaomi wireless AR glasses exploration version.

3. Balance between lightweight and durability
Through finite element analysis (FEA) to simulate the frame force, optimize the topology structure, and reduce redundant weight while ensuring strength. For example, a customer project used this technology to reduce the frame weight from 28 grams to 19 grams, and the durability still met the 100,000 opening and closing tests.

III. Future Trends: Innovative Directions for AR Glasses Materials
As AR devices develop towards daily wear, JARKEL Casting is developing the following technologies:
1. Degradable magnesium alloy: Through surface modification technology, the corrosion resistance of magnesium alloy in humid environments is extended to adapt to diverse usage scenarios.
2. Intelligent sensor integration: Embed flexible sensors in magnesium alloy frames to achieve real-time monitoring of data such as pressure and temperature, and enable the active interaction capabilities of AR glasses.

With a deep understanding of the characteristics of magnesium alloy materials and innovative processes, JARKEL Casting provides the AR glasses industry with solutions that combine performance and cost. Successful cases have confirmed the irreplaceable nature of magnesium alloys in lightweight, heat dissipation and structural design. In the future, JARKEL will continue to promote the integration of material science and manufacturing technology, and help AR glasses move from "technological products" to a new era of "daily wear".
