Explore our premium architectural, industrial, and high-conductivity thermal solutions manufactured at our state-of-the-art facilities.
In the era of hyper-computation, electrification, and 5G telecommunication, thermal management has transitioned from a supporting engineering challenge to a core performance differentiator. High-density electronics generate unprecedented heat fluxes that must be dissipated rapidly to protect components and sustain operational longevity. This is where extruded aluminum heat sink profiles emerge as the premier solution.
Aluminum alloys, particularly the 6xxx series, offer a highly optimized balance between high thermal conductivity, low weight, high mechanical strength, and exceptional design versatility. By leveraging the extrusion process, custom manufacturers can produce intricate fin structures and geometry profiles that maximize convective surface area while minimizing airflow resistance.
Whether cooling EV traction inverters, heavy-duty photovoltaic converters, industrial power modules, or compact LED channel components, optimized aluminum extrusions act as the primary conduit for conductive and convective heat dissipation. High-performance factories must control grain structures, alloy purities, and dimensional tolerances with sub-millimeter precision.
Guangdong represents the absolute global epicenter of aluminum extrusion manufacturing. Sourcing from a leading Chinese manufacturer offers structural and operational advantages.
From aluminum ingot smelting and custom alloy formulation to complex mold/die engineering, precision extrusion (900T - 2000T), surface anodization, and high-precision multi-axis CNC machining, our entire process is synchronized under a single system to minimize waste and lead times.
With access to over 100,000 sets of existing molds, we significantly reduce tooling costs for common profiles. For custom components, our dedicated in-house mold tooling design and testing lab ensures we can prototype high-aspect-ratio heat sinks and multi-port hollow profiles rapidly.
By producing over 100,000 tons of aluminum alloy profiles annually, we command immense raw material purchasing power. Through lean management, automated production lines, and optimized logistics routing from Guangdong (Sihui & Foshan), we achieve sustainable competitive pricing.
Industrial thermal management is evolving rapidly. Discover how our customized aluminum profiles solve real-world problems in high-growth sectors.
Modern EV battery packs require consistent temperature zones to maintain charge capacity and prevent thermal runaway. We manufacture high-precision EV floorboard profiles and thin-walled multi-void cooling plates that integrate liquid-coolant channels directly into the structural aluminum framework.
By utilizing high-conductivity 6063 alloys and controlled T5/T6 tempering, our components provide both structural rigidity for crash safety and rapid heat transfer routes to the vehicle's active refrigeration loop.
5G transceivers process enormous volumes of data, generating localized heat fluxes in sealed outdoor enclosures. Our custom high-fin-density aluminum heat sinks are extruded with high aspect ratios, allowing natural convection to cool sealed housings without active fans.
Specialized surface treatments, such as heavy-layer black anodizing, improve radiation heat transfer coefficients, ensuring operations survive intense solar loading and marine-grade atmospheric corrosion.
Solar and wind power conversion setups rely on heavy-duty IGBT modules to invert DC current to grid-compliant AC. These IGBTs produce severe localized heat bursts. We supply heavy industrial comb-profile heat sinks with base plate thicknesses up to 20mm and heights up to 100mm.
Our precision CNC processing ensures the mounting faces are machined to extreme flatness tolerances (under 0.05mm), eliminating thermal contact resistance when bolted to power semiconductors.
High-output LED linear lighting systems decay rapidly if junction temperatures exceed critical thresholds. We manufacture miniature custom micro-channels and aluminum profiles that double as modern design elements (such as cornices, skirting boards, and window framing) and heat sinks.
Combining function and aesthetics, our anodized and powder-coated LED channels offer high heat dissipation while integrating with high-end modern interiors.
Established in 2009, Aoli Aluminum is a leading enterprise integrating research and development, manufacturing, and international sales. Under our flagship brand "Aolijie", we specialize in high-quality aluminum alloy profiles for construction, industrial machinery, and electrical engineering.
Our strategic journey began in 2000 when founder Mr. Wong recognized the vast environmental and structural benefits of aluminum extrusion. In 2009, we built our first 10,000 square meter factory in Sihui, Guangdong. Today, we operate 4 manufacturing plants covering 100,000 square meters, delivering over 100,000 tons of high-grade extrusion products annually.
"Our mission is building sustainable cities for the world. Committed to achieving a win-win situation for employees, customers, and society has always been our business vision."
A history of continuous investments in heavy machineries, certifications, and global footprint expansion.
Our initial Sihui City factory was built, offering specialized extrusion lines to supply standard profiles. The "Aolijie" brand was established: A (First choice), LI (Leading Indicator), JIE (Masterwork in Chinese).
During this period of intense R&D, we secured 13 product utility patents, modernized our extrusion processes, and implemented ISO9000 quality systems to qualify for international infrastructure supply chains.
To keep pace with the boom in structural solar and industrial electronics, we built our new 100,000 square meter facility, integrating high-capacity lines ranging from 900 tons to 2,000 tons.
Following the establishment of our domestic sales hub in Foshan in 2024, we are planning the launch of our regional service office in Malaysia in 2026 to support Southeast Asian and Western procurement managers directly.
Thermal profiles must meet strict internal metallurgical and tolerance standards. We perform 100% inspections and random AQL sampling based on ISO 2859 / ANSI/ASQ Z1.4.
Selecting the optimal alloy ensures the proper balance of thermal performance, machinability, and mechanical strength.
