Explore our foundational range of premium custom extrusions, framing systems, and architectural profiles engineered for robust performance.
In modern electrical engineering, hardware design, and telecommunications infrastructure, the choice of enclosure material determines the longevity, safety, and functionality of sensitive electronics. Extruded aluminum boxes—often referred to as electronic aluminum enclosures or aluminum housings—have emerged as the global standard for protecting high-value industrial and electronic components.
Unlike plastic or sheet metal alternatives, extruded aluminum boxes offer a unique blend of structural rigidity, lightweight architecture, high thermal conductivity, and inherent electromagnetic interference (EMI/RFI) shielding. This makes them indispensable in demanding global sectors: from IoT edge gateway enclosures deployed in high-temperature oil rigs, to battery containment modules for micro-mobility electric vehicles, to high-frequency power inverter housings in solar micro-grids.
Because extruded profiles can integrate integral heat-sinking fins directly into the shell design, they act as their own passive cooling mechanisms, eliminating the weight, noise, and potential failure points of active cooling fans.
Choosing the correct alloy and temper ensures optimal structural properties and machinability. Our systems rely on high-grade 6000-series aluminum alloys.
We source architectural-grade 6063 for complex profile geometries with smooth surface finishes, and structural-grade 6061 for heavy mechanical load applications requiring high tensile strength and fracture toughness.
Aluminum is naturally conductive, providing effective shielding against electromagnetic and radio frequency interference without the need for secondary coatings, critical for sensitive telecommunications and EV floorboards.
Through controlled anodizing (Type II or Type III hard coat) and PVDF powder-coating systems, our aluminum enclosures withstand extreme outdoor and marine environments, complying with ISO and ASTM standards.
For international buyers and OEM partners, sourcing extruded aluminum boxes from Aoli Aluminum provides a strategic, cost-effective competitive edge. Operating out of Sihui City, Guangdong, with our specialized sales and engineering interface in Foshan, we sit directly within the world's most advanced aluminum industrial cluster.
This geographic concentration creates deep supply chain integrations. Raw ingot procurement, die design and custom tool production, high-capacity extrusion lines, comprehensive post-extrusion CNC machining, and state-of-the-art surface finish lines are all executed locally. This reduces transit times, minimizes manufacturing friction, and lowers overheads.
Our vertically integrated manufacturing setup permits high production speed. We turn custom profile drawings into production-ready dies within 7 to 10 days, allowing global engineering teams to complete hardware iterations rapidly.
Dedicated to engineering high-precision aluminum profiles and enclosures that support sustainable, modern infrastructure worldwide.
At the core of Aoli Aluminum lies the brand mission: Building sustainable cities for the world. We strive to strike a harmonious balance between operational output, environmental protection, and employee well-being, assuring our global buyers that their supply chain partner operates responsibly.
Our core value system rests on three pillars:
AO ("First choice") represents our goal of being our customers' primary option; LI ("Leading Indicator") points to our position within the industry; and Jie ("Master Work") reflects our focus on quality. Aolijie is your assurance of outstanding Chinese engineering guided by industry standards.
Trace the growth of Aoli Aluminum from a local extrusion plant in Guangdong to a globally recognized supplier of industrial aluminum systems.
A standard aluminum profile factory covering 10,000 square meters was established in Sihui City, Guangdong. The brand "Aolijie" was founded, dedicated to producing industry-leading standard aluminum profiles.
Based on strict requirements for product quality and production management, we obtained 13 product patents and ISO9000 certification during this era, cementing our market presence.
Driven by strong global demand, we expanded to a 100,000 square meter factory complex in 2017, elevating our annual production capacity to 100,000 tons of structural extrusions.
Establishing our specialized export sales division in Foshan (2024), we are expanding our supply chain reach with a planned international office in Malaysia (2026) to streamline B2B procurement across APAC and Western regions.
A look inside our 4 production bases featuring advanced extrusion presses ranging from 900 tons to 2,000 tons, surface treatment facilities, and CNC machining centers.
Our brand "Aolijie" features surface treatment lines including powder coating, anodizing, electrophoretic coating, PVDF coating, wood grain sublimation, die production, and CNC processing equipment, alongside specialized architectural window and door lines.
We implement a strict quality control matrix: 100% visual inspection, 5% secondary spot checks, and random AQL sampling (ISO 2859 / ANSI/ASQ Z1.4).
Every single batch of extruded enclosures is documented. Our in-house testing laboratory ensures mechanical compliance, alloy composition, and durability limits under hard service conditions.
Our standard testing sequence covers structural safety, chemical analysis, and coating endurance under harsh environmental conditions.
Aoli Aluminum is ISO 9001 and ISO 14001 certified. Material properties are verified through mill test certificates (MTC) and Third-Party inspections upon request.

A technical guide for procurement managers and design engineers seeking to optimize costs and mechanical performance.
For electronic enclosures, extrusion is simply the first step. Our factories provide full secondary processing via high-precision CNC machining centers. This includes drilling, milling out cutouts for LCD screens, tapping holes for cable glands, and engraving logos or indicators.
When design engineers specify layout dimensions, maintaining standard tolerances (typically DIN ISO 2768-m) ensures cost-effective production without unnecessarily tight, cost-prohibitive constraints.
For outdoor, automotive, or industrial plant environments, protecting internal PCBs against dust and water is vital. Extruded aluminum boxes can easily achieve IP65, IP66, or IP67 ratings through:
1. Precision-engineered tongue-and-groove enclosure joints.
2. Formed-in-place liquid silicone rubber (LSR) gaskets.
3. Anodized and sealed faceplates secured with corrosion-resistant stainless steel fasteners.
• Alloy Grade: 6063 for complex designs, 6061 for maximum strength.
• Wall Thickness: Typically 1.5mm to 4.0mm to balance weight with structural integrity.
• Thermal Dissipation: Fin density and height calculations relative to passive heat loads.
• Surface Coatings: Clear, black, or custom color anodizing for corrosion and aesthetic appeal.
• Tooling Amortization: Custom mold costs are typically amortized and refunded over high-volume production orders.
