Extrusion Technology & Metallurgical Engineering

We deploy advanced extrusion technology and strict quality workflows to meet extreme architectural performance metrics.

Alloy Selection & Precision Mechanical Properties

We primarily utilize AA6063, AA6061, and AA6005 high-grade virgin aluminum billets. For window systems, 6063-T5 and T6 tempers offer optimized tensile strengths up to 250 MPa, yielding high wind-load resistance and durability for structural curtain wall profiles.

Thermal Barrier (Polyamide Strip) Integration

To comply with modern building insulation standards (such as Energy Star and EU thermal regulations), we integrate PA66-GF25 structural fiberglass-reinforced polyamide strips. This lowers the thermal transmittance (U-factor) of window profiles by up to 50%, minimizing condensation and HVAC costs.

Advanced Surface Treatment Protocols

Our production bases house fully automated lines for electrostatic powder coating (AAMA 2604/2605 compliant), acid-etch anodizing, electrophoretic sealing, and PVDF coatings. These treatments ensure a durable outer layer resistant to UV degradation and salt spray corrosion.

Sihui & Foshan Supply Chain Resilience

China's Pearl River Delta is the world's most dense ecosystem for non-ferrous metal manufacturing. The integration of Aoli Aluminum's production bases in Sihui with our logistics hub in Foshan provides our global clientele with a significant competitive advantage:

  • Vertically Integrated Operations: From billet casting and custom die fabrication to CNC deep machining, surface coatings, and protective packaging, every step is controlled in-house. This cuts out middle-man logistics markups and ensures production efficiency.
  • Rapid Tooling Turnaround: With a library of over 100,000 active molds, standard profiles can be extruded immediately. Custom dies are engineered by our design division and cut using high-precision CNC wire EDM machines within 7 to 10 days.
  • Strategic Raw Material Sourcing: By purchasing raw aluminum in bulk contracts directly from major domestic smelters, we hedge against volatile LME price swings, passing the cost savings onto our wholesale buyers.
Aoli Aluminum Automated Extrusion Production Lines

Our Brand: "Aolijie"

The story of Aolijie reflects the rapid expansion and modernization of China's industrial aluminum extrusion industry.

The brand name "Aolijie" carries a deep commitment to excellence: "AO" represents the absolute first choice (No.1 option), "LI" signals our position as a leading indicator of global standards, and "JIE" translates to a masterwork (outstanding craftsmanship) in Chinese. Thus, Aolijie represents high-performing products guided by industry-leading indicators.

2009: Factory Establishment & Brand Creation

A standard manufacturing plant covering 10,000 square meters was established and commissioned in Sihui, Guangdong. The brand "Aolijie" was launched to specialize in high-precision structural and architectural profiles.

2010-2016: Quality Standardizations

Focused on quality management, securing 13 key structural patents and full ISO9001:2008 and ISO14001 certifications. Standardized chemical and mechanical inspection testing labs were integrated into the plant.

Quality Standardizations and Certifications

2017-2020: Manufacturing Upscaling

To support growing international orders, we invested in a new 100,000 square meter production facility. We upgraded our hardware with extrusion presses ranging from 900 to 2,000 tons, pushing annual capacity to 100,000 metric tons.

New Automated Manufacturing Plants

2024-2026: Global Reach & Expansion

Established a specialized export branch in Foshan to handle direct international sales. Plans are underway to establish a Southeast Asian service center in Malaysia by 2026, offering local support and technical advice to global developers.

Global Application & Regulatory Compliance

Our engineering division configures structural extrusions to meet local building codes across various key regions.

North America (AAMA & ASTM Standards)

We supply window frames engineered to meet AAMA 101 standards for water penetration, air leakage, and wind load. Our electrostatic powder coatings can be formulated to meet AAMA 2605 specifications, providing 10+ years of color retention in coastal areas.

Europe (EN standards & CE Marking)

Our thermal break profiles align with EN 14024 tests for mechanical resistance and thermal insulation. We assist structural engineers with CE marking requirements by providing detailed declaration of performance (DoP) data sheets.

Oceania & SEA (AS2047 & Local Wind Loads)

To withstand extreme wind zones in coastal regions, our profiles are designed with deeper glazing pockets. This allows for thicker laminated double-glazed units (IGUs) that satisfy the AS2047 window performance standard.

Engineering & Wholesale Procurement FAQ

Key technical answers to guide procurement, architectural specification, and logistics planning.

1. What are the key chemical differences between 6063 and 6061 alloys for window extrusions?
6063 alloy is formulated with lower levels of silicon and magnesium, making it highly extrudable. This yields cleaner surface finishes ideal for anodizing and powder coating. 6061 is a structurally superior structural alloy containing higher concentrations of magnesium, silicon, and trace elements of copper. It is typically reserved for heavy-duty industrial framing and structural components rather than highly decorative window frames.
2. How does the thermal break system prevent heat transfer?
Aluminum is a highly conductive metal. A thermal break system inserts a low-conductivity material (typically PA66-GF25 structural polyamide strips) between the interior and exterior aluminum profiles. This creates a thermal barrier that interrupts the path of heat conduction, reducing the system's overall U-value and helping prevent interior surface condensation.
3. What is your custom die tooling cost policy for new profile designs?
We charge a standard tool steel die fee for customized designs. However, once your combined order volume for that specific profile reaches a set threshold (typically 3 to 5 tons, depending on profile dimensions), the tooling fee is fully refunded or credited back to your account.
4. How do you package extrusions to prevent surface damage during ocean shipping?
Each profile is individually wrapped with protective PE film or interleaved with paper. The bundles are then packed into heavy-duty cardboard boxes, steel racks, or wooden crates. This packaging is designed to withstand moisture and movement during sea transit, ensuring the profiles arrive at your facility in pristine condition.
