Our Operational Advantages

Vertically integrated systems engineered to maximize dimensional accuracy, reduce manufacturing costs, and speed up lead times.

Material Properties Control

We melt and cast aluminum alloys in-house. This gives us tight control over the exact chemical compositions of our raw billets. By keeping trace elements in check, we achieve excellent mechanical properties in our extrusions, structural integrity under high loads, and high purity for clean surface finishes like anodizing.

Integrated Process & Quality Control

Our facility handles every step of production under one roof, from extrusion and precision multi-axis CNC milling to custom surface finishing. By eliminating mid-process outsourcing, we lower transport costs and keep strict quality control in place. We deliver premium components at competitive prices.

Fast & Predictable Delivery

Our integrated manufacturing line keeps production moving efficiently. Transitioning smoothly from billet casting to extrusion and high-speed CNC milling cuts down on delays. This allows us to offer shorter, reliable lead times that support just-in-time procurement schedules for global supply chains.

Global Corporate Procurement & Solutions

How our manufacturing capabilities solve design, engineering, and supply-chain challenges across global industrial sectors.

Automotive & Electric Vehicles

Our high-strength 6XXX and 7XXX alloy components meet the automotive industry's focus on lightweight design. We produce crash management systems, structural chassis links, battery enclosures, and precision acoustic profiles. These parts improve structural strength while reducing vehicle weight to extend EV range.

Consumer Electronics & 3C

For consumer electronics, we manufacture thin-walled, heat-dissipating enclosures and structural frames. We use multi-axis CNC milling, ultra-fine sandblasting, and chemical anodizing to create premium, durable finishes. Our parts feature high thermal conductivity, EMI shielding, and precise tolerances.

Architectural & Envelope Systems

We supply heavy-duty curtain wall structures, dynamic skylight hinges, and weather-resistant door profiles. These components are designed to withstand high wind loads and thermal expansion. Offered with bronze anodizing and electrophoretic coatings, they ensure long-term durability in challenging outdoor environments.

Technical Roadmap: Alloy Chemistry & Extrusion Limits

Engineered chemical structures and precision processing ranges to meet demanding applications.

To ensure stability under load and clean finishes after machining, we customize the microstructural phases of our aluminum alloys. By controlling the ratios of magnesium (Mg) and silicon (Si) in our 6000 series, we prevent cracking during extrusion and optimize the distribution of Mg2Si precipitates. For high-stress applications, our 7000 series alloys (like 7075) undergo custom aging treatments (T6, T651) to increase tensile strength while maintaining resistance to stress corrosion cracking.

Alloy Class Key Elements Tensile Strength (MPa) Machinability Index Primary Industrial Applications
1XXX Series (e.g. 1060) Al ≥ 99.00% 70 - 100 Low Busbars, heat transfer tubes, chemical process vessels.
3XXX Series (e.g. 3003) Mn (1.0 - 1.5%) 110 - 160 Medium Heat exchangers, condenser cores, general sheet metal parts.
5XXX Series (e.g. 5052) Mg (2.2 - 2.8%) 190 - 260 Good Marine fittings, fuel tanks, transport sheet components.
6XXX Series (e.g. 6063) Mg (0.45-0.9%), Si (0.2-0.6%) 150 - 240 Excellent Intricate extrusions, architectural profiles, heat sinks.
6XXX Series (e.g. 6061) Mg (0.8-1.2%), Si (0.4-0.8%) 260 - 310 Excellent Structural frames, precision CNC parts, automotive links.
7XXX Series (e.g. 7075) Zn (5.1-6.1%), Mg (2.1-2.9%) 500 - 570 Excellent High-stress structural parts, aerospace fittings, climbing gear.

OEM Aluminum Milling Pricelist Framework

A transparent breakdown of how material rates, processing times, and surface treatments influence our pricing structure.

OEM aluminum machining costs are calculated using a structured formula. This includes the raw material weight (adjusted to global metal markets like the LME/SHFE index), extrusion press time, CNC cycle times, tool wear, and surface treatment requirements. Performing casting, extrusion, machining, and anodizing under one roof helps reduce transport costs and eliminate middleman markups.

Raw Metal Index Pricing

Calculated using current market rates per metric ton for raw ingots, plus a conversion fee for specific alloys (such as 6063, 6061, or 7075).

Extrusion Tooling Amortization

Custom profiles require an initial tool tooling investment. For high-volume production runs, this cost is fully amortized, which reduces the per-unit cost.

Machining Cycle Time

Pricing is based on the complexity of features. Multi-axis CNC milling, drilling, tapping, and tight tolerances (under ±0.01 mm) determine the cycle time cost.

Surface Treatment Scale

Finishing costs depend on the type of treatment. Options range from standard industrial sandblasting and clear anodizing to specialized multi-stage bronze anodizing or powder coating.

International Certifications & Awards

Certified management, material traceability, and environmental compliance supporting international supply integration.

To serve global markets, we maintain a certified quality system. We operate under ISO 9001, ISO 14001, and ISO 45001 standards. Additionally, we hold newer, stringent environmental certifications like GRS (Global Recycled Standard) and RCV. These ensure our alloys use high proportions of recycled content, helping global brands meet circular economy requirements. All extruded and machined materials comply with the EU’s REACH and RoHS directives.

Technical & Commercial FAQ

Answers to key questions regarding alloy chemistry, machining capabilities, and shipping processes.

What makes Foshan Golden Source different from other CNC machining factories?
We operate a fully integrated 73,000 SQM facility that handles billet casting, die design, extrusion, precision CNC machining, welding, and surface treatment. By avoiding outsourcing, we control chemical purity for better anodizing, lower costs, and offer faster, more predictable shipping.
Which aluminum alloys do you cast and machine?
We process 1XXX, 3XXX, 5XXX, 6XXX, and 7XXX series alloys. For structural parts, we often use 6063-T6, 6061-T6, and high-strength 7075-T6, adjusting chemical compositions to optimize strength and anodizing quality.
Do your materials comply with environmental regulations in the EU and US?
Yes. Our products comply with REACH and RoHS standards. We also hold GRS (Global Recycled Standard) and RCV certifications, which document the use of recycled metal in our alloys to help brands meet sustainability goals.
How are tooling costs handled for custom OEM designs?
We design and build dies in-house to lower tooling costs. A tooling deposit is charged initially, but this cost can be fully amortized or refunded once order volumes reach agreed-upon quantities.
