Explore our custom-engineered aluminum extrusions, precision machined, finished, and optimized to meet rigorous application standards globally.
Established in 1991, Foshan Golden Source Precision Manufacturing Co., Ltd has developed into an internationally recognized manufacturer specializing in high-strength, high-precision customized aluminum profiles, structural components, and post-machined assemblies. Our manufacturing complex spans a modern, environmentally conscious area of over 73,000 square meters.
We solve the complexities of modern engineering by providing an integrated, "one-stop" production sequence. Our services encompass alloy melting & casting, custom mold design and manufacturing, advanced extrusion, precision CNC machining (drilling, milling, tapping), welding (robotic & manual), surface finish treatments, and final structural assembly. This full integration ensures structural predictability, absolute dimensional accuracy, and cost efficiency for demanding industries.
By leveraging certified quality systems including ISO9001, ISO14001, ISO45001, and pioneering environmental compliance like GRS (Global Recycled Standard) and RCV certifications, our products fully meet the safety and eco-conscious parameters of the European Union’s REACH and RoHS regulations. Our multi-alloy capability supports 1XXX, 3XXX, 5XXX, 6XXX, and 7XXX series alloys, accommodating requirements across automotive, 3C electronics, railway transit, outdoor sports, and home structural fixtures.

Why global procurement offices and structural engineers prioritize Golden Source for custom profile development.
We refine and melt raw aluminum in-house, optimizing chemical compositions to enhance the physical properties of our finished profiles. Precise micro-alloying ensures metallurgical purity, which prevents defects during high-ratio extrusion and results in consistent anodizing outcomes.
By conducting tooling design, extrusion, precision CNC machining, and surface treatments under a single roof, we eliminate double-handling, transit wear, and third-party markup. This integrated capability allows us to offer premium structural quality at competitive prices.
Our vertically integrated operations minimize lead times between different production stages. Seamless coordination from tool-making to finished assembly speeds up prototyping and shortens supply chains for high-volume orders.
Different engineering challenges demand specific alloy compositions. Review our capabilities across the major aluminum categories.

Our integrated processing line transforms raw ingots into functional component assemblies with strict quality checks at every step.
Pure raw ingots are melted in-house to tailor metallurgical characteristics and cast precise billets.
Our in-house design team engineers and cuts dies using CNC EDM to meet precise tolerance specifications.
Billets are pre-heated and pressed through custom dies, followed by controlled air/water quenching.
Extrusion lengths undergo multi-axis CNC milling, drilling, tapping, and custom bending.
Profiles are finished with sandblasting, brushing, clear/color anodizing, or custom powder coating.
Individual elements are joined via precision welding or mechanical fasteners and packed for dispatch.
Operating out of Foshan, the capital of aluminum manufacturing, we offer reliable logistics and global compliance standardizations.
Foshan is a major global hub for aluminum extrusion. This concentrated industrial ecosystem provides access to raw materials, specialized tooling houses, surface finish specialists, and experienced logistical networks. Consequently, we can secure material components and auxiliary treatments at lower costs and with shorter lead times than geographically isolated factories.
Proximity to major ports in Guangzhou, Shenzhen, and Hong Kong facilitates international shipping. We offer flexible shipping arrangements, including FOB, CIF, DDU, and DDP terms, to streamline delivery to regional warehouses and manufacturing facilities.
Global procurement offices must navigate evolving environmental regulations. Golden Source has obtained GRS (Global Recycled Standard) and RCV certifications to address the growing demand for low-carbon products, especially in the European Union.
Our materials comply with EU REACH and RoHS regulations, preventing heavy metal contamination and facilitating customs clearance. Whether you are building components for automotive systems, consumer electronics, or architectural frameworks, our compliance documentation supports your local regulatory reporting.
Our commitment to quality, environmental responsibility, and workplace safety is backed by international certifications and government awards.
We maintain certifications for ISO9001, ISO14001, and ISO45001 to ensure consistent quality and safety standards. Our GRS and RCV certifications demonstrate our commitment to meeting environmental regulations in international markets. In addition, we have received regional and provincial awards recognizing our investments in clean production, technological upgrades, and creditworthiness.
Learn how industrial manufacturers structure extrusion prices, and discover strategies to optimize your procurement budget.
Industrial aluminum extrusion pricing typically follows a structured formula to ensure transparency across fluctuating global markets:
The raw ingot cost fluctuates with metal market indices (such as the London Metal Exchange or Shanghai Metal Market). The processing fee reflects production variables, including profile complexity, wall thickness, and alloy difficulty (e.g., 7075 requires more tonnage and slower extrusion speeds than 6063).
Several critical factors dictate the final cost of customized aluminum extrusions:
Answers to common technical, commercial, and logistics questions from procurement and engineering teams.
More industrial profiles engineered to close tolerances, featuring specialized surface finishes and assembly preparation.
