Explore our high-precision structural and architectural profiles engineered to withstand harsh environments and mechanical loads.
An in-depth look into heat dissipation technology, alloy optimization, and the high-efficiency trends driving modern power electronics.
In the era of rapid industrial electrification, telecommunication upgrades (5G/6G), and Electric Vehicle (EV) advancements, thermal management has transitioned from a supporting engineering requirement to a key performance bottleneck. Efficient heat dissipation directly dictates the lifespan, safety, and operational efficiency of high-density semiconductor chips, power converters, and lithium-ion batteries. Custom aluminum extrusion heat sinks are the primary passive cooling mechanism utilized globally to address these challenging thermal loads.
Modern electronic packaging demands smaller form factors while dissipating greater quantities of thermal energy. Traditional stamped or cast heat sinks often fall short in high-performance applications due to material density limitations or inadequate thermal conductivity. Extruded aluminum profile heat sinks offer optimized longitudinal grain structures and flexible design pathways, enabling high-aspect-ratio fin designs (deep, narrow grooves) that maximize natural or forced convective cooling.
Procuring thermal components on a global scale requires balancing complex variables: raw material purity, geometric precision, and specialized post-processing. Strategic procurement managers prioritize suppliers utilizing verified 6063 or 6061 alloy configurations. While 6063-T5 aluminum provides superior thermal conductivity (~200 W/m·K), 6061-T6 offers higher tensile strength and structural integrity under heavy mechanical loads.
Our state-of-the-art facility maintains strict control over extrusion ratios and die wear, guaranteeing tight geometric tolerances that reduce gaps between heat sources and heat sinks. This dramatically lowers Overall Thermal Interface Resistance when paired with advanced Thermal Interface Materials (TIMs).
Engineered for maximum thermal conductivity, achieving up to 200 W/m·K. Excellent anodizing response ensures highly durable surface finishes.
Capable of producing complex thin-fin heat sinks with aspect ratios up to 15:1 to 20:1, yielding larger surface areas for maximum dissipation in confined configurations.
Fully integrated CNC vertical machining centers provide highly accurate hole drilling, counterboring, milling, tapping, and precise mounting surface flatness down to <0.05mm.

Our brand "Aolijie" is closely related to the development of aluminum profiles in China. Since 2000, our founder Mr. Wong has been engaged in the sales of building materials industry. At that time, China's real estate was in a rapid development trend, marking the official start of China's building aluminum profile industry.
Aluminum profiles are an environmentally friendly, low-carbon, sturdy, and durable material. Mr. Wong is keenly aware of the significance of aluminum profiles for future urban architecture, which will surely benefit the world. Therefore, the dream of producing high-quality aluminum profiles emerged from then on. In 2009, he finally established a factory for aluminum profiles under the brand name "Aolijie".
"AO" - A is the first of all letters (No. 1 meaning), O refers to "option", meaning "First Choice".
"LI" - L refers to "leading", I refers to "indicator", meaning "Leading Indicator".
"Jie" - Means "master work" in Chinese.
Aolijie: Your first choice - outstanding Chinese products guided by industry-leading indicators.
A standard aluminum profile factory covering an area of 10,000 square meters was established and put into production in Sihui City, Guangdong Province. 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 between 2010 and 2016.
Due to positive market feedback, we invested in the construction of a 100,000 square meter factory in 2017, increasing our annual output to 100,000 tons.
In 2024, we established a sales branch in Foshan, Guangdong, and will soon set up our first overseas office in Malaysia in 2026 to offer closer localized customer support.

Pioneering the next generation of high-power thermal solutions while maintaining absolute environmental compliance.
As cooling demands scale past traditional limits, Aoli Aluminum is aggressively expanding its engineering scope. Our technical roadmap focuses on three main pillars designed to resolve the thermal challenges of next-generation power electronics:
By utilizing FSW, we join multiple high-aspect-ratio extruded segments into extra-wide thermal cold plates. This achieves void-free joint lines with minimal thermal resistance, surpassing the dimensional restrictions of typical extrusion presses.
For local hot-spots, we integrate copper heat pipes directly into pre-milled grooves in the extruded aluminum base. This hybrid approach pairs the fast phase-change heat transfer of copper with the lightweight dissipation of aluminum.
We are scaling up production of multi-void microchannel tubes and liquid-cooled manifolds. These profiles feature complex inner geometries to facilitate high-pressure fluid flow, ideal for Electric Vehicle battery packs and server racks.
Our raw materials and manufacturing processes are strictly aligned with international directives. We guarantee that all exported industrial profiles are fully compliant with the European Union's RoHS (Restriction of Hazardous Substances) and REACH regulations. Every delivery is accompanied by complete material certifications, chemical analysis reports, and mechanical inspection sheets, ensuring absolute transparency for global electronics manufacturers.
Find direct answers to common queries regarding extrusion capabilities, custom tooling, lead times, and thermal engineering.
Our facility houses extrusion presses ranging from 900 tons to 2,000 tons. This machinery enables us to produce custom profiles up to 250mm in circle size. For wider profiles, we utilize advanced post-extrusion techniques such as Friction Stir Welding (FSW) to assemble modular profiles into extra-large configurations.
Alloy 6063 is the industry standard for extrusion heat sinks because it offers superior thermal conductivity (typically around 200-209 W/m·K) compared to 6061 (around 150-170 W/m·K). Furthermore, 6063 provides a smoother surface finish and is easier to extrude into complex, thin-finned structures. 6061 is preferred for structural components that require high mechanical strength.
We provide a comprehensive range of surface treatments in-house. For electronics heat sinks, anodizing (clear, black, or color) is the most common finish. It enhances corrosion resistance, provides electric isolation (under specific anodic layer thicknesses), and increases surface emissivity, which improves radiative heat transfer. We also offer powder coating, PVDF coating, and chemical conversion treatments.
For custom designs, die fabrication and initial sample production generally take 10 to 15 days. Once the samples are approved by the client, bulk production runs typically take 20 to 25 days depending on the complexity of the profiles and secondary processing (such as CNC machining and anodizing).
We follow strict ISO 2859 and ANSI/ASQ Z1.4 quality standards. High-precision calipers, projectors, and coordinate measuring machines (CMM) are used in our QC lab to ensure dimensional compliance. For critical mounting locations, we achieve tolerances down to ±0.05mm through precision CNC machining.
