Explore our high-precision custom aluminum profiles and industrial sub-assemblies engineered for critical field operations.
Established in 1991, Foshan Golden Source Precision Manufacturing Co., Ltd has built a strong reputation over three decades as a premium manufacturer of high-strength, high-precision custom aluminum profiles and machined parts. Over the past 30+ years, we have transitioned from a localized extrusion plant to a global one-stop industrial supply chain partner.
Operating a state-of-the-art, eco-friendly manufacturing base spanning over 73,000 square meters, our facilities are built to support massive production scales while maintaining tight structural tolerances. We offer fully integrated in-house manufacturing capabilities, starting from custom alloy smelting and casting to mold research, design, extrusion, precise CNC machining, welding, structural assembly, and specialized surface finishing.

Why Tier-1 engineering firms, construction groups, and automotive manufacturers source from Golden Source.
We melt and cast aluminum alloys in-house. This allows us to adjust raw chemical compositions dynamically to achieve optimal physical and mechanical properties. By controlling trace elements like Iron, Silicon, and Magnesium, we improve extrusion profiles and deliver clean, consistent alloy structures required for high-purity anodizing.
Our facilities combine extrusion, CNC machining, stamping, and surface finishing under a single QA protocol. By keeping operations in-house, we eliminate external transport risks, reduce production cycles, and pass down cost-efficiencies. This ensures our components match tight dimensional tolerances and perform reliably in the field.
By handling tooling development, extrusion, precise cutting, CNC milling, surface finishing, and custom packaging in a single facility, we offer shortened lead times. This integrated setup simplifies communication for our global clients, cutting logistics delays and accelerating time-to-market.
The structural integrity of an aluminum tube or custom profile starts with its microstructural grain configuration. Industrial extrusion requires tailored compositions depending on whether the profile needs high tensile strength, bendability, or a clean surface finish. We process a range of standard and custom alloys to meet these specific demands:
| Alloy Grade | Temper | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) |
|---|---|---|---|---|
| 6063 | T5 | ≥ 160 | ≥ 110 | ≥ 8 |
| 6063 | T6 | ≥ 205 | ≥ 180 | ≥ 8 |
| 6061 | T6 | ≥ 265 | ≥ 245 | ≥ 8 |
| 6082 | T6 | ≥ 310 | ≥ 260 | ≥ 10 |
| 7075 | T6 | ≥ 540 | ≥ 480 | ≥ 7 |
Custom-engineered aluminum profiles supporting modern infrastructure, logistics, and consumer tech.
Our structural extrusions, like our CNC-machined roof rack supports, help reduce vehicle weight in EV designs. Engineered from 6063-T5 alloy with powder-coated finishes, these structural profiles withstand high mechanical loads while keeping vehicle weight down.
Automotive Light-weightingWe supply high-precision sliding tracks and hanging kit door components for metro trains. Machined from 6063-T6 alloy with a sandblasted and clear anodized finish, these components are designed to withstand continuous cycles in daily transit operations.
Rail Transit & LogisticsOur custom anodized wave boards, angles, and framing brackets provide structural support and clean aesthetics for modern building envelopes. These profiles are treated for high UV and environmental resistance, ensuring long-term durability in outdoor installations.
Structural Glazing & FacadesTo support global supply chains, our production processes align with rigorous international quality and environmental standards. We maintain comprehensive certifications to ensure seamless integration into automotive, electronics, and structural projects:
A closer look at our custom engineering capabilities, from initial tool design to advanced surface finishing.
Our in-house design team works with custom specifications, modeling hollow shapes and thin-walled profiles in CAD/CAM to ensure correct metal flow during extrusion.
We run multiple extrusion presses with automated handling. Nitrogen shielding helps minimize surface oxidation and maintain profile dimensions.
We provide secondary operations including multi-axis CNC milling, precision cutting, stamping, and drilling to deliver assembly-ready parts directly to your production line.
We offer standard anodizing, bronze anodizing, sandblasting, and powder coating. All surface finishes are checked for thickness and salt-spray resistance.
