In the current era of "Lightweighting" and "Sustainable Manufacturing," customized aluminum profiles have transitioned from simple structural components to critical enablers of high-tech innovation. From the aerospace chassis to the sleek thermal management of LED lighting, the precision of extrusion defines the performance of the end product.
Utilization of high-performance 6000 and 7000 series alloys to meet specific tensile strengths, corrosion resistance, and conductivity requirements for rail transit and automotive applications.
Leveraging state-of-the-art 2500T and 1450T extruders combined with AI-driven cooling systems to ensure dimensional stability and zero-defect surface finishes.
Transitioning toward low-carbon "Green Aluminum" sourcing and energy-efficient recycling processes, aligning with global sustainability mandates like the EU CBAM.
Located in the Jimo District of Qingdao, Qingdao Kangjian Aluminum Industry Technology Co., Ltd. is a leader in the R&D and manufacturing of specialized aluminum alloy profiles. Established with a vision to fill the void in high-end domestic extrusion, we have rapidly evolved into a global partner for Rail Transit, Aerospace, Automotive, and Marine industries.
Our infrastructure includes a 200 mu production base with 80,000 square meters of high-tech facilities. With an annual output of 15,000 tons and five advanced extrusion lines (up to 2500T), we are uniquely positioned to handle complex, large-scale industrial projects.
Qingdao offers a unique "Dual-Sea Layout," providing immediate access to primary aluminum smelting, specialized surface treatment providers, and world-class logistics through the Qingdao Port.
Chinese factories are no longer just "extruders." We provide vertical integration, including 5-axis CNC machining, precision drilling, and complex assembly for robotics and drone components.
The speed from CAD design to die-casting and first-article extrusion is significantly faster in China, reducing the Time-to-Market for global enterprises by up to 40%.
Customization is the heartbeat of modern industrial applications. Here is how customized aluminum profiles are solving complex engineering challenges:
High-strength, lightweight profiles for high-speed railways and subways. These profiles must meet rigorous safety standards (EN15085) and vibration resistance while reducing the overall weight of the carriage to enhance energy efficiency.
Anodized aluminum frames for photovoltaic brackets require 25-year corrosion resistance. For EVs, aluminum battery trays provide superior thermal conductivity and crashworthiness compared to steel.
Precision is paramount. Our extruded kits for smart robot cars and drone frames utilize 6061-T6 aluminum, ensuring a high strength-to-weight ratio for increased agility and battery life.
U-Channel and V-Shape profiles for LED linear lighting act as both a structural frame and a heat sink, significantly extending the lifespan of high-intensity LEDs.
When selecting a China-based aluminum factory, prioritize the following E-E-A-T factors:
MOQ varies depending on the profile's complexity. Generally, for standard 6063 alloys, the MOQ is 500kg. However, for specialized industrial components requiring new dies, we can support smaller trial runs during the R&D phase.
For marine environments, we recommend 5083 or 6082 alloys. These offer exceptional resistance to salt-water corrosion and maintain structural integrity under high-moisture conditions.
Yes, we provide a full range of finishes including clear/color anodizing, hard-anodizing for industrial wear resistance, electrophoresis, and architectural-grade powder coating (Qualicoat standard).
We utilize high-precision 3-axis and 5-axis CNC centers. Every batch undergoes CMM (Coordinate Measuring Machine) inspection to ensure tolerances as tight as ±0.01mm, depending on customer requirements.
Typically, die design and sample extrusion take 10-15 days. Upon sample approval, mass production is completed within 15-20 days, depending on the volume and surface treatment requirements.
Qingdao Kangjian Aluminum Industry Technology Co., Ltd. was officially registered in 2022. The enterprise mainly produces and processes aluminum and aluminum alloy products.
