Engineered to the highest industry tolerances, our heavy-duty profiles support diverse structural and enclosure applications globally.
In modern industrial electronics, communication nodes, and green energy applications, the aluminum enclosure acts as both a protective barrier and a thermal management component. As structural architectures shrink and power levels rise, thermal load demands have grown exponentially.
This comprehensive industry review explores modern extrusion dynamics, advanced precision manufacturing tolerances, thermal properties of specific aluminum grades (such as Al-Mg-Si alloys), and strict validation protocols that distinguish world-class Chinese aluminum fabricators. Through optimized engineering, our brand, Aolijie, delivers robust solutions tailored for heavy industry, telecommunication networks, EV infrastructure, and high-performance computing.
Explore the strategic shifts and material breakthroughs shaping the next generation of protective metallic housings.
Integration of low-profile, high-fin-density heat sinks directly into extruded enclosure designs. Utilizing high thermal conductivity alloys, we achieve structural protection and efficient passive cooling in a single component.
Modern electrical grids, RF networks, and high-frequency communication protocols require housings with integrated electromagnetic protection. Aluminum inherently blocks electromagnetic interference, protecting internal circuitry.
By applying controlled anodizing processes and specialized outdoor powders, our architectural and industrial enclosures withstand long-term exposure to salt spray, moisture, and chemical washes.
Founded in 2009 by Mr. Wong, the brand name "Aolijie" represents a commitment to high-quality manufacturing and service. The name reflects our values:
Our headquarters are located in Sihui, Guangdong, with sales and distribution hubs in Foshan, ensuring a seamless supply chain from extrusion to export shipping.
A history of continuous growth, capacity expansion, and technical development.
Aoli Aluminum established its first 10,000-square-meter facility in Sihui, Guangdong, producing standard profiles and industrial framing under the "Aolijie" brand.
Obtained 13 utility patents and ISO 9001 certification. Established rigorous quality controls to serve international markets.
Invested in a new 100,000-square-meter manufacturing site, increasing annual output capacity to 100,000 tons with high-tonnage extrusion presses.
Opened our Foshan branch to manage global exports. Planning to open a regional office in Malaysia in 2026 to support Southeast Asian customers.
A corporate culture designed to support customer success and structural integrity.

Aolijie profiles and enclosures are utilized in architectural and industrial projects worldwide.
A technical guide to chemical composition, mechanical properties, and surface finish options for aluminum enclosures.
Choosing the correct aluminum grade is critical for structural and thermal performance in industrial applications. We primarily utilize 6063 and 6061 grades. The chemical limits and silicon-to-magnesium ratios are tightly controlled to prevent structural weaknesses.
| Alloy Grade | Si (%) | Mg (%) | Fe (%) | Tensile Strength (MPa) | Thermal Conductivity (W/m·K) |
|---|---|---|---|---|---|
| 6063-T5 | 0.2 - 0.6 | 0.45 - 0.9 | ≤ 0.35 | ≥ 160 | ~ 200 |
| 6063-T6 | 0.2 - 0.6 | 0.45 - 0.9 | ≤ 0.35 | ≥ 205 | ~ 201 |
| 6061-T6 | 0.4 - 0.8 | 0.8 - 1.2 | ≤ 0.70 | ≥ 290 | ~ 166 |
Aolijie offers several surface finishing options to meet specific requirements for durability and aesthetics:
Our deep processing workshop offers precision services, including cutting, drilling, tapping, milling, deburring, and high-speed CNC routing. We maintain tight tolerances (up to ±0.05 mm), ensuring reliable fitment and assembly of enclosure lids, glands, and internal PCBs.
Answers to common questions regarding specifications, lead times, and engineering options.
We primarily use 6063-T5/T6 for complex profiles due to its surface finish quality and extrudability, and 6061-T6 for enclosures requiring higher mechanical strength and structural load support.
We apply specialized external coatings, such as PVDF or architectural-grade powder coatings. Additionally, we conduct regular salt spray testing (ASTM B117) and UV aging tests to ensure long-term durability in outdoor environments.
Die design and production typically take 10 to 15 days, depending on profile complexity. Sample approvals are processed shortly after, followed by full-scale production once approved.
Yes, we provide integrated services. Our facilities include multi-axis CNC machines, precision cut-off saws, punching presses, and tapping equipment, allowing us to deliver ready-to-assemble components.
We perform 100% visual inspections and random AQL sampling based on ISO 2859 and ANSI/ASQ Z1.4. Each shipment is accompanied by a material certificate and quality inspection report.
Yes. We manufacture customized thermal break profiles using high-quality polyamide (PA66-GF25) thermal barriers, helping to improve energy efficiency in window, door, and curtain wall installations.
