Explore our custom OEM/ODM CNC machined, extruded, and assembled aluminum solutions engineered to tight industry tolerances.
Founded in 1991, Foshan Golden Source Precision Manufacturing Co., Ltd. stands as a benchmark in custom aluminum profile assembly and precision manufacturing. Operating from our environmentally conscious, modern production complex spanning more than 73,000 square meters, we maintain complete control over the fabrication value chain.
Our end-to-end operational structure eliminates external reliance, managing in-house alloy casting, structural mold research, development and tooling production, precise profile extrusion, high-accuracy multi-axis CNC machining, structural welding, and advanced protective surface finishes. By consolidating these steps under one roof, we guarantee minimal material handling delay, rapid turnaround, and robust dimensional control.
We work across a broad range of alloy matrices—including the 1XXX, 3XXX, 5XXX, 6XXX, and 7XXX series—tailoring thermal temper, mechanical yield strengths, and grain structures to match the specifications of industries such as rolling stock components, automotive parts, structural architecture, consumer devices (3C), and functional interior systems.

Why global OEMs partner with Foshan Golden Source for complex structural systems and profile assemblies.
By melting and compounding our aluminum alloys in-house, we control trace element chemistry to ensure excellent grain uniformity, predictable extrusion yields, and superior anodizing quality.
With extrusion, high-precision machining, and surface treatment managed under a single manufacturing flow, we maintain strict control over tolerances, minimize defect rates, and offer competitive unit costs.
Our vertically integrated production steps cut lead times, simplify supply chains, and enable prompt project updates from raw extrusion to finished, assembled modules.

| 1XXX Series (e.g., 1060, 1070) | O, H14, H24 | High electrical & thermal conductivity; high ductility; excellent corrosion resistance. | Electrical busbars, heat sinks, electronic shielding frames. |
| 3XXX Series (e.g., 3003) | O, H14, H18 | Moderate strength; excellent workability & weldability; good corrosion resistance. | Heat exchangers, cooling tubes, battery housing shells. |
| 5XXX Series (e.g., 5052, 5083) | O, H32, H34, H112 | High fatigue strength; excellent saltwater corrosion resistance; good weldability. | Marine fittings, transportation fuel tanks, sub-structural frames. |
| 6XXX Series (e.g., 6061, 6063, 6082) | T4, T5, T6 | Balanced tensile strength, yield strength, workability, and anodizing response. | Structural framing, CNC housings, heat sinks, vehicle structural members. |
| 7XXX Series (e.g., 7075) | T6, T651 | Very high tensile strength (equivalent to structural steels); high fatigue resistance. | Aerospace linkages, military tooling, high-load structural assemblies. |
Precision profiles require careful handling after extrusion. Our facility is equipped with multi-axis CNC machining centers, automated cutting systems, precision mills, and indexable drills to work with tolerances as close as ±0.01mm, depending on size. This precision ensures that components align perfectly during final assembly, preventing structural stress and saving time during installation.
Beyond producing basic extrusions, we deliver complete, ready-to-install structural systems. We offer several joining options depending on load, sealing, and service requirements:
To shield parts from harsh environments and meet styling requirements, we provide comprehensive, in-house surface treatment options:
Delivering tailored aluminum solutions across diverse global industries.
Lightweight components for EVs, battery tray structures, suspension links, and heavy-duty metro car doors. Engineered for crash absorption and strict weight targets.
Thin-wall extrusions and structural chassis for portable consumer electronics, high-efficiency heat dissipation structures, and outdoor cellular enclosures.
Robust profiles for solar panel mounts, weather-resistant curtain walls, architectural framing, and specialty window structures designed for high wind resistance.
Modern global logistics require reliable manufacturing partners. Foshan Golden Source leverages advanced production systems to ensure reliable, high-volume capacity and consistent, documented quality.
Our centralized production campus houses melting, tooling, extrusion, machining, and finishing lines in a single location. This vertical integration reduces logistics costs, prevents transit damage, and keeps lead times predictable.
Through active capacity monitoring and automated production scheduling, we minimize bottlenecks and scale output smoothly to match seasonal demand spikes.
We maintain a comprehensive suite of quality, safety, and environmental certifications to comply with strict international regulatory requirements.
Our operations are certified to ISO 9001:2015 (Quality Management), ISO 14001:2015 (Environmental Management), and ISO 45001:2018 (Occupational Health & Safety). Our products comply with European environmental regulations, including REACH. We also hold newer GRS (Global Recycled Standard) and RCV (Recycled Content Verification) certifications to support sustainable, low-carbon manufacturing initiatives.
How we are evolving our materials, processes, and technology to support next-generation designs.
Industrial manufacturing is increasingly focused on reducing its environmental footprint. We continue to expand the use of recycled alloys under our GRS framework, working to lower carbon emissions without compromising mechanical performance.
We are also optimizing our casting and heat treatment processes to reduce energy consumption, helping our customers hit their Scope 3 sustainability targets.
As modern systems demand lighter, stronger materials, we are developing advanced 6XXX and 7XXX series alloys. These formulations are designed to offer high tensile strength, good energy absorption, and excellent stability for structural automotive and electrical components.
Additionally, we are refining our tooling and die designs to allow for thinner walls and more complex geometries, reducing raw material usage while maintaining structural integrity.
