Premium-grade structural frames, thermal barrier systems, and specialized industrial enclosure profiles developed for global scale projects.
Aluminium extrusion cases represent the pinnacle of structural protection for sensitive electronics, EV power distribution nodes, and communications architecture. Globally, enterprises are transitioning from standard stamped steel sheet-metal enclosures toward customized, high-precision extruded aluminium designs. This structural evolution is driven by aluminium's superior high strength-to-weight ratio, native electromagnetic interference (EMI) shielding capabilities, and phenomenal natural thermal conductivity.
For procurement officers, engineering departments, and global system integrators, selecting the ideal manufacturing partner in China is no longer merely about driving unit costs down. It is an intricate equation balancing alloy purity (typically 6063-T5 or 6063-T6), dimensional wall-thickness tolerances, structural design complexity, localized compliance profiles, and surface treatment integrity.
Extruded enclosures feature seamless monolithic walls that optimize structural load pathways. They integrate integrated interior card guide rails, heat sink fins, and slide-in slots, which completely eliminates post-assembly steps and vastly improves mechanical integrity.
Established in 2009, Aoli Aluminum merges high-level research & development with industrial-scale extrusion and CNC deep processing capabilities.
Aoli Aluminum (brand name "Aolijie") operates as an ISO-certified, vertically integrated manufacturer of premium-grade aluminium alloy profiles. Headquartered in the major industrial zone of Sihui, Guangdong, with specialized corporate branches in Foshan, Guangdong, we have built a manufacturing footprint designed to satisfy complex architectural and industrial engineering needs globally.
Our proprietary brand "Aolijie" encompasses 4 state-of-the-art production bases. Equipped with advanced extrusion lines ranging from 900 tons to 2,000 tons capacity, we handle surface treatment technologies including powder coating, clear & color anodizing, electrophoretic coating, PVDF coating, simulated wood grain transfer, and custom tool/die manufacturing alongside CNC deep processing systems.
With an annual production capacity reaching 100,000 tons and an archive of over 100,000 sets of existing molds across 100 distinct series, Aoli offers unparalleled scalability. We customize components using thermal-break engineering, precision mechanical checks, and high-performance alloy formulations for key markets in the Middle East, South America, Africa, and Southeast Asia.
Our mission is building sustainable cities for the world. We firmly prioritize client-first relationships, considering our customers' success as our responsibility. Employee development and brand reputation remain the non-negotiable cornerstones of our operational framework.
Our primary brand "Aolijie" is deeply linked to the historical modernization of structural metallurgy in China. In 2000, our founder Mr. Wong began working within building materials sales. Observing the explosive growth of urban architecture in China, he realized that high-strength, lightweight, and recyclable aluminium extrusions represented the sustainable future of urban infrastructure.
By 2009, he established the production facility to manufacture these advanced profiles under a brand that carries our deep engineering intent:
Sihui City, Guangdong, became our primary home with a 10,000 square meter factory designed to satisfy regional and global profiles.
Obtained 13 core technological patents and secured full ISO 9001:2015 certification for standard-setting process management.
Invested heavily in scaling up to a 100,000 square meter production center, setting up a 100,000-ton capacity baseline.
Opened our Foshan branch to service international trading and finalized operations for a localized sales office in Malaysia to support ASEAN customers.
How localized material sourcing and advanced industrial clusters optimize cost, efficiency, and engineering precision.
Our facility handles every phase under a unified roof: raw aluminum ingot casting, computer-aided die design and wire-EDM cutting, extrusion, thermal-break assembly, customized electrochemical surface treatment, and precision multi-axis CNC drilling and milling.
Situated within the South China aluminum cluster, Aoli benefits from direct access to premier primary smelting centers, auxiliary hardware manufacturers, and direct logistical ports. This proximity reduces overland transport times and optimizes material lead-times.
Our internal mold design department optimizes flow channels dynamically, minimizing material waste during production starts. Furthermore, we amortize tool engineering across high-volume production, offering competitive pricing margins without sacrificing quality.
Our quality system features 100% manual inspections and strict AQL spot checks (ISO 2859 / ANSI/ASQ Z1.4) conducted at our internal laboratories.

To maintain strict performance metrics, each production lot undergoes: (1) Alloy verification via spectrometer chemical testing; (2) Mechanical testing for yield and tensile strength limits; (3) Webster hardness checks; (4) Digital caliper dimensional tracking down to ±0.02mm; (5) Eddy-current coating checks; (6) Corrosive resistance evaluation; (7) UV weatherability exposure testing; and (8) 100% physical surface checks prior to packing.
From electric vehicle chassis members to modern building envelopes, Aolijie extrusions meet demanding industrial specifications.
Modern battery electric vehicle (BEV) architectures require structural under-trays that serve dual purposes: protecting battery cell matrices during physical impact and conducting heat away from critical modules. Our precision-engineered floorboard profiles integrate internal hollow multi-chamber designs that absorb deformation energy while supporting cooling channels.
Large structural projects require profile designs that can handle wind-load deflection while limiting thermal transfer. Our high-performance thermal break window frames utilize reinforced polyamide (PA66-GF25) strips to separate the exterior and interior aluminum structures, improving energy efficiency.
For outdoor telecommunication boxes and high-capacity power bank enclosures, aluminum's innate EMI shielding isolates internal electronics from RF interference. Anodizing finishes provide outstanding environmental protection, passing extended salt spray tests for offshore deployments.
T-slot modular solutions enable engineers to construct machine bases, structural guards, and custom workstations dynamically. Our T-slot components maintain precise slot positioning for secure connections and reliable heavy-duty industrial assembly.

Expert answers regarding engineering specifications, custom tool designs, alloy selection, and lead times.
We primarily utilize raw premium grades of 6063-T5 and 6063-T6 aluminum alloys. 6063 provides a balance of surface finish quality and tensile strength, making it ideal for precision enclosure walls, thermal management fins, and structural framing. For high-stress applications, we also manufacture 6061-T6 on request.
Our multi-axis CNC milling, drilling, and cutting equipment maintains high precision, holding dimensional tolerances as tight as ±0.02mm to ±0.05mm. This accuracy ensures that PCB guide channels, dynamic faceplate mountings, and seal gaskets fit securely during final product assembly.
We operate dedicated, state-of-the-art lines for: (1) Anodizing, which yields a hard, corrosion-resistant surface ideal for heat sinks and electronics cases; (2) Powder Coating, which provides a durable finish in a wide range of colors; (3) Electrophoretic Coatings, which deliver uniform coverage; and (4) PVDF Coating, which offers excellent UV and weather resistance for outdoor installations.
We maintain an in-house tool design department. Customers send us their physical drawings (DWG/DXF) or 3D files (STEP/IGS). Our engineering team reviews the profile for proper flow, cuts the custom dies using wire-EDM machines, runs a test sample for approval, and then schedules production. This end-to-end integration reduces lead times.
For new custom profiles, die manufacturing and sample testing usually take 10 to 14 working days. Once the sample is approved, bulk production is typically completed in 15 to 20 days, depending on order size and chosen surface finishes. We coordinate logistics from our Sihui and Foshan hubs to optimize shipping schedules.
We operate under a strict quality management system based on ISO standards. We perform 100% visual checks on the lines, backed by random sampling under AQL systems (ISO 2859). Each production run receives a Quality Inspection Report detailing composition, mechanical properties, coating thickness, and dimensions.
