Explore our custom high-grade extrusion profiles and structural CNC-machined components engineered for key industries.
In modern mechanical design and manufacturing, the demand for precision, structural efficiency, and metallurgical integrity has intensified. As lightweighting becomes a core design criterion for automotive, aerospace, robotics, and renewable energy industries, finding a partner that seamlessly bridges heavy industrial aluminum extrusion with micron-accurate CNC machining is paramount.
Qingdao Kangjian Aluminum Industry Technology Co., Ltd. serves as a leading force in China's customized aluminum sector. Established in 2022, we operate a 200-mu industrial manufacturing base featuring 80,000 square meters of highly automated factory space in Qingdao, China. Equipped with advanced multi-ton press lines ranging from 700T to 2500T, and integrated with multi-axis CNC milling centers, we supply critical structural assemblies worldwide.
This whitepaper details our technological roadmap, material science capabilities, and factory workflows to illustrate how our engineering-driven manufacturing delivers substantial information gain and cost-efficiencies for international procurement organizations.
Integrating intelligent production paradigms with next-generation metallurgical engineering.
We are evolving our CNC lines toward fully automated 5-axis continuous milling centers. By consolidating operations, we minimize setup variances and maintain structural geometries within true position tolerances below 0.02mm.
We are developing advanced 6000 and 7000-series chemical matrices with customized silicon, magnesium, and copper ratios. This enhances grain structure alignment and mechanical performance during heavy extrusion phases.
Our engineering workflow leverages simulation software to forecast extrusion die wear and thermal deformation. This allows pre-emptive correction of tooling dimensions, ensuring consistent product runs over large batch quantities.
Tailoring structural performance to meet the demands of advanced vertical industries.
Modern robotic mechanical arms require high structural rigidity paired with low rotational inertia. Our precision 6061 and 6063 T6 structural base mounts and arm segments are extruded and then CNC-milled on all faces. This achieves lightweight performance without compromising load capacity, reducing motor wear and power usage in high-cycle packaging and assembly cells.
Solar frames must withstand environmental exposure, wind loads, and thermal expansion cycles. We extrude and punch photovoltaic aluminum alloy profile frames. These are finished with type III hard coat anodization to prevent atmospheric and chemical corrosion over their 25-year operational lifespans.
Our facility is certified to the stringent IATF 16949 and ISO 22163 (IRIS) standards. We supply structural chassis parts, train body panels, lightweight EV battery enclosures, and marine-grade components. These profiles are designed to absorb crash energy and provide consistent strength-to-weight performance.
Unmanned aerial vehicles depend on lightweight, high-strength frames to maximize payload capacity and flight times. We produce CNC-machined drone arms and structural hardware. These components are milled to thin-walled geometries from aircraft-grade aluminum, maintaining structural integrity under high dynamic forces.
How our manufacturing infrastructure translates to shorter lead times and stable supply chains for global enterprises.
Operating from Jimo District, Qingdao, our facility spans 80,000 square meters of production space. We feature a range of five extrusion lines—including 700T, 1150T, 1450T, and a heavy-duty 2500T extruder. This setup allows us to manufacture complex thin-walled sections as well as large structural profiles on a single site.
By combining extrusion and CNC machining, we eliminate inter-facility logistics delays, reduce the risk of handling damage, and simplify quality control. Our annual output capacity of 15,000 tons ensures we can handle high-volume procurement runs without compromising production schedules.
Proximity to the Port of Qingdao provides reliable ocean freight links to North American, European, and Asian markets. This reduces land transit times and mitigates international logistics bottlenecks.
Cross-referencing global standards to ensure seamless integration into international supply chains.
For international engineering teams, material specification alignment is critical. We work within ASTM, EN, and GB frameworks to guarantee that raw material properties match specified parameters, including tensile strength, yield strength, and elongation limits.
| Alloy (AA Standard) | Chinese Equivalent (GB/T) | European Standard (EN) | Tensile Strength (MPa, Typ) | Yield Strength (MPa, Typ) | Primary Industrial Applications |
|---|---|---|---|---|---|
| 6061-T6 | LD30 | AW-6061 / AlMg1SiCu | ≥ 290 | ≥ 240 | Robotic Arms, Structural Mounts, Drone Parts |
| 6063-T5 | LD31-T5 | AW-6063 / AlMg0.7Si | ≥ 186 | ≥ 145 | LED Profiles, Windows, Decorative Frame Parts |
| 7075-T6 | LC4 | AW-7075 / AlZn5.5MgCu | ≥ 540 | ≥ 480 | Aerospace Structures, High-Stress UAV Gears |
| 5083-H111 | LF4 | AW-5083 / AlMg4.5Mn0.7 | ≥ 275 | ≥ 125 | Marine Structures, Oil Drilling Platforms |
How we address international standards, regulatory compliances, and risk mitigation.
We hold certifications for EN15085-2 Class CL1 (railway applications), ISO3834-2 (fusion welding of metallic materials), and DIN6701 Class A2 (adhesive bonding of rail vehicles). These credentials demonstrate our capacity to produce assemblies capable of withstanding dynamic operational forces.
Our ISO9001:2016 management framework governs every phase of production. From raw billet spectrometry validation through dimensional metrology reporting, to final surface treatment testing, we provide full material and process traceability.
We offer a range of finishing options, including multi-color anodizing, hard coat anodization, powder coating, sandblasting, and chemical conversion treatments. This allows us to meet specific requirements for cosmetic appearance, electrical isolation, or corrosion protection.

Answers to technical and logistical questions for engineering and procurement managers.
For standard runs, we work to ISO 2768-m (medium) standards. For critical structural interfaces, we can achieve tolerances down to ±0.02mm using multi-axis CNC milling centers. Final tolerances depend on the cross-sectional geometry of the profile and the material temper.
The IATF 16949 certification requires a system of defect prevention and variance reduction throughout our supply chain. We apply failure mode effects analysis (FMEA) and control plans to all automotive-grade extrusions and CNC parts to maintain product consistency across large production runs.
Yes. We handle die design, extrusion production on our five press lines (up to 2500T), heat treatment, and subsequent CNC machining under a single manufacturing workflow. This saves handling time and consolidates quality accountability.
We provide custom surface finishing, including clear and color anodizing, hard coat anodization, sandblasting, powder coating, and PVDF coatings. For outdoor architectural or marine environments, we recommend a minimum anodizing film thickness of 15-25 microns to ensure long-term durability.
