Browse our core inventory of premium, precision-engineered extrusions fabricated directly from our specialized factory bases.
Founded in 2009, Aoli Aluminum (brand name: Aolijie) has established itself as an authoritative manufacturer integrating comprehensive metallurgical research and development, high-volume production, and precision custom processing. Headquartered in Sihui, Guangdong, and supported by modern branch offices in Foshan, we operate at the epicenter of China's aluminum industrial manufacturing cluster.
By leveraging an ISO-certified quality management framework, we guarantee structural integrity, compliance with strict international material directives, and unprecedented dimensional accuracy. From modular industrial frameworks to advanced dynamic movement architectures, our solutions support clean energy, industrial automation, and construction sectors globally.
Understanding structural differences is critical for high-efficiency mechanical engineering and modular frame assembly. While standard T-slot extrusions are typically designed for static frame connections and guards, V-Slot aluminum profiles integrate a flat, 90-degree chamfered edge along the inner slot. This specialized profile geometry allows V-wheels, bearings, and linear guides to seat directly and ride smoothly within the slot, functioning as both structural support and linear guide rails.
| Performance Indicator | V-Slot Aluminum Profile | Standard T-Slot Profile | Engineering Benefit |
|---|---|---|---|
| Primary Application | Linear motion systems, CNC machines, actuators | Static frames, enclosures, machine guards | Eliminates the cost of separate linear guide rails |
| Profile Groove Geometry | 90° V-shaped internal chamfered track | Square flat-bottom internal channel | Direct interface with V-guide wheels for smooth translation |
| Structural Materials | 6063-T5 / T6 Premium Structural Aluminum | 6061-T6 or 6063-T5 Extruded Aluminum | Maintains rigid stability under dynamic load cycles |
| Surface Finishes | Satin/Clear Anodized, Black Hard Anodized | Clear Anodized, Powder Coated | Enhanced wear resistance along linear track contact surfaces |
| Deflection Tolerance | Extremely low (Strict adherence to EN 755-9) | Standard industrial structural limits | Ensures precision alignment for moving toolheads |
As an industry-leading factory, Aolijie controls the chemical properties of raw billets prior to hot extrusion. The typical composition of our 6063 alloy optimizes Silicon (0.2-0.6%) and Magnesium (0.45-0.9%) ranges to produce profiles with excellent surface finish quality and anodizing receptivity, while retaining necessary mechanical properties: tensile strength ≥160 MPa, yield strength ≥110 MPa, and elongation ≥8%.
From a local standard extrusion facility to a global leader in high-performance aluminum engineering.
Our founder, Mr. Wong, began his venture in the structural construction materials sector in 2000, identifying the emerging need for low-carbon, robust, and recyclable framing solutions. This vision culminated in the establishment of the factory brand Aolijie in 2009.
A standard aluminum profile factory covering 10,000 square meters was established in Sihui City, Guangdong Province, launching the Aolijie brand into market sectors requiring strict dimensional tolerances.
Implemented robust ISO 9000 quality systems, developed specialized in-house thermal barrier methods, and obtained 13 proprietary product patents for profile architecture.
Constructed our modern 100,000 square meter factory base to scale annual production capacity to 100,000 metric tons. Supported high-volume international demand across the Americas and EU.
Established our main export sales division in Foshan City. Slated for 2026, our overseas regional branch in Malaysia will expand localized support and direct delivery for Southeast Asian projects.
Discover how procurement managers optimize their overhead and reduce logistics risk through our strategic integration.
We perform die-casting billet creation, tooling design, profile extrusion, surface anodizing, powder coating, and precision multi-axis CNC secondary processing under one unified facility system. This structure reduces handling times, eliminates third-party logistics markup, and guarantees complete process traceability.
Our quality verification processes execute random Acceptable Quality Level (AQL) inspection patterns conforming to ISO 2859 and ANSI/ASQ Z1.4. Each dispatch is validated with chemical composition analyses, tensile test documentation, and mechanical hardness metrics.
Our factories conform to international environmental policies. We supply V-Slot profiles compliant with RoHS, REACH, and energy-efficiency directives. By integrating high-performance thermal break technology, we assist global builders in achieving LEED building credentials.

Straightness and twist deviations are primarily controlled during the post-extrusion cooling and stretching phases. Our facility uses multi-directional hydraulic tension straighteners and precision induction hardening systems. We guarantee straightness deviations below 0.3mm per meter, exceeding the standard tolerance specifications of GB/T 5237 and EN 755-9.
Yes, we customize tooling in-house. Upon receiving CAD blueprints (.dwg, .dxf, .step), our engineering team designs and manufactures extrusion dies using slow-wire EDM cutting machines. Standard die preparation requires 10 to 14 days, followed by sample testing within 3 days. Production runs typically complete within 15 to 20 days post-sample approval.
For V-Slot extrusions supporting linear bearings, we recommend hard-coat clear or black anodizing (thickness 12μm - 15μm). Anodizing increases surface hardness and wear resistance, reducing friction and extending the operating life of carbon-steel or polyoxymethylene (POM) guide wheels.
We maintain long-term supply contracts with primary aluminum smelting operations in China to secure stable ingot supply. Pricing models can be indexed to either LME (London Metal Exchange) or SMM (Shanghai Metal Market) commodity prices, combined with fixed fabrication fees, providing clear cost breakdowns for overseas buyers.
