Why do the world's top 5 AR brands choose JARKEL Casting's magnesium alloy structural parts? Revealing the manufacturing code of lightweight AR glasses

As augmented reality (AR) technology moves from concept to consumer market, users have higher requirements for the comfort and durability of the equipment. Traditional plastic or aluminum alloy structural parts can no longer meet the needs of high-performance AR glasses, and magnesium alloy AR glasses structural parts have become the new favorite of the industry with their unique performance advantages. JARKEL Casting, a world-leading precision casting company, relies on its innovative magnesium alloy process.

Part 1: Why has magnesium alloy become the "golden material" for AR glasses?

The king of lightweight, upgraded wearing experience
The density of magnesium alloy is only 1.8g/cm³, which is 33% lighter than aluminum alloy and 10 times stronger than engineering plastics. JARKEL Casting uses ultra-thin die-casting technology to control the weight of AR glasses frames to less than 15g, completely solving the problem of nose pressure caused by long-term wear.

Double breakthrough in heat dissipation and electromagnetic shielding
The Micro-OLED screen and computing module of AR glasses will generate high heat, and the thermal conductivity of magnesium alloy is as high as 140W/(m·K), which is 200 times faster than plastic. The honeycomb heat dissipation structure developed by JARKEL Casting, combined with the vacuum coating process, can reduce the temperature of core components by 12°C. At the same time, its electromagnetic shielding efficiency reaches 60dB, perfectly protecting 5G/Wi-Fi 6E signal transmission.

Military-grade impact resistance
Adopting JARKEL Casting's patented AZ91D-HD magnesium alloy formula, the yield strength is increased to 220MPa, passing 100,000 hinge opening and closing tests and 1.2-meter drop tests, far exceeding the MIL-STD-810G military standard.

Part II: JARKEL Casting's 4 core technologies
Nano-level precision die-casting system
Invested 20 million US dollars to introduce the German Frech 2800T vacuum die-casting machine, and cooperated with the AI-driven mold flow analysis system to control the flow rate of magnesium alloy melt at ±0.5m/s, and achieve 0.05mm precision microporous structure molding to meet the assembly requirements of waveguide lenses.

Global exclusive surface treatment solution
For the pain point of salt spray corrosion of AR glasses, JARKEL Casting has developed Micro-arc Oxidation+PTFE composite coating technology, with a corrosion resistance time of more than 1000 hours (ASTM B117 standard), and the surface friction coefficient is reduced to 0.08, which is convenient for traceless disassembly and maintenance.

Full-process digital twin quality control
Deploy 30 quality monitoring nodes from raw material spectral analysis to finished product CT scanning. Through blockchain technology, the traceability of each product is achieved, and the yield rate is stable at 99.98%, reaching aerospace grade standards.

Flexible mass production capability
In the Dongguan factory, JARKEL Casting has built a modular production line that can be quickly switched, supporting flexible orders from 100,000 to 5 million pieces, and shortening the delivery cycle to 15 days, helping customers seize market opportunities.

JARKEL Casting is planning three major innovation directions:

Degradable magnesium alloy: Research and develop Mg-Zn-Ca materials that can be decomposed in the natural environment to reduce electronic waste

3D printing integrated structure: Cooperate with EOS to develop SLM magnesium alloy printing process to achieve zero assembly error temple-mainboard compartment integrated design

Intelligent sensing structure: Embed optical fiber sensors in the magnesium alloy matrix to monitor deformation and temperature data in real time
