Aluminum alloy drone structural components

Product Overview: Aluminum Alloy Drone Structural Components

Our aluminum alloy drone structural components are precision-cast custom parts tailored for various UAV types, including industrial inspection drones, agricultural spraying drones, logistics delivery drones, and consumer-grade aerial photography drones. Core products cover drone fuselage frames, wing/rotor brackets, landing gear, battery compartments, and payload mounting bases—all crafted from high-performance aluminum alloys that balance lightweight and strength. The core functions include: bearing the overall weight of the drone, resisting aerodynamic pressure and vibration during flight, protecting internal electronic components, and ensuring precise assembly of key modules. Leveraging our professional experience in UAV components, we optimize product structures to reduce weight by 3-8% compared to conventional designs, perfectly matching the "lightweight and high-strength" core requirement of drones. Meanwhile, we supply matching auxiliary cast iron parts (such as anti-vibration bases) to meet comprehensive assembly needs. All products comply with international UAV component standards (RoHS, CE) and pass strict environmental adaptability tests (high and low temperature, humidity, salt spray), ensuring reliable performance in harsh flight environments.

Production Processes & Workflow (UAV-Specific Optimization)

Combining our expertise in UAV components and advanced aluminum alloy casting technology, we adopt a refined and visualized production process to ensure the precision, lightweight, and reliability of each drone structural part. The core production process (focused on gravity casting and low-pressure casting for UAV parts) includes:

1. UAV-Specific Demand Analysis & Design Optimization: Our technical team, with rich experience in UAV component design, conducts in-depth communication with customers to clarify requirements (flight load, flight environment, dimensional tolerance, assembly matching). Using CAD/CAM/CAE software, we perform 3D modeling and finite element analysis (FEA) to simulate flight stress and vibration. We optimize the part structure by adding lightweight ribs and hollow designs, ensuring structural strength while minimizing weight. For key parts like landing gear, we conduct fatigue strength tests in the design stage to avoid failure during takeoff and landing.

2. High-Performance Aluminum Alloy Selection & Inspection: Strictly select aluminum alloys suitable for UAV applications (A356, 6061, 7075, ADC12) with excellent casting performance, high specific strength, and good corrosion resistance. These materials are specially processed to reduce internal impurities, ensuring stable mechanical properties. We conduct comprehensive raw material testing, including chemical composition analysis (via spectrometer) and mechanical property detection (tensile test, hardness test), to ensure materials meet UAV flight safety requirements.

3. Precision Mold Making for UAV Parts: For drone structural components with high precision and complex shapes, we adopt high-precision mold manufacturing technology. The mold core and cavity are processed by CNC machining centers and EDM to ensure dimensional tolerance ±0.02mm. For small-batch custom UAV projects, we use rapid mold development technology, shortening the mold cycle by 25% to help customers accelerate new product launch.

4. Core Casting Process (Gravity/Low-Pressure Casting): We mainly adopt gravity casting and low-pressure casting for aluminum alloy drone parts—these processes ensure uniform material structure, low porosity, and high dimensional accuracy, which are critical for UAV flight stability. The casting temperature is precisely controlled at 670-710℃, and the pouring speed is adjusted according to the part thickness to avoid turbulence and internal defects. For large-size fuselage frames, low-pressure casting is used to ensure dense texture; for small precision parts like rotor brackets, gravity casting is adopted to improve production efficiency.

5. UAV-Oriented Post-Casting Processing: After casting, parts undergo trimming, shot blasting (SA2.5 standard), and deburring to remove surface defects. Precision machining is then performed using CNC lathes and milling machines to ensure key assembly dimensions (such as hole position tolerance) meet requirements. For parts requiring anti-vibration, we conduct dynamic balance testing and secondary correction.

6. Targeted Surface Treatment for UAVs: Provide surface treatment options adapted to UAV flight environments: anodizing (clear/black) to enhance corrosion resistance and wear resistance while maintaining lightweight; sand blasting to improve surface adhesion for subsequent coating; electrophoresis to achieve a smooth surface and reduce air resistance during flight. All treatments comply with RoHS environmental standards and do not increase excessive weight.

7. Strict UAV-Specific Quality Inspection: Implement multi-level quality control tailored to UAV components. Key inspections include: dimensional inspection (via Coordinate Measuring Machine, CMM) to ensure precision; non-destructive testing (ultrasonic, X-ray) to detect internal defects; weight testing to ensure lightweight requirements; vibration and fatigue testing to verify flight stability; and salt spray testing (≥48 hours) to confirm corrosion resistance. Only products passing all inspections can be delivered.

In addition to the core gravity/low-pressure casting processes, we also master die casting and investment casting technologies, which can be flexibly applied to auxiliary UAV components (such as cast iron counterweights) or special-shaped parts, providing comprehensive production support for UAV manufacturers.

Customer Case: Custom Drone Structural Components for a US Industrial UAV Manufacturer

A leading US industrial UAV manufacturer approached us to customize 6061 aluminum alloy fuselage frames and rotor brackets for their new high-altitude inspection drone. Their core requirements included: extreme lightweight (weight reduction by 18% compared to their original design), tensile strength ≥320MPa, dimensional tolerance ±0.03mm, resistance to -40℃~60℃ high-low temperature environments, and a delivery cycle of 22 working days (including mold development). Our UAV-specialized technical team conducted finite element analysis on the original design, optimizing the frame structure by adding hollow ribs and reducing redundant material—successfully achieving the weight reduction target while improving tensile strength by 5%. During mold development, we used rapid prototyping technology to complete the mold in 10 working days and provided 8 sets of samples for flight vibration testing. In production, we adopted low-pressure casting to ensure part density, and performed black anodizing and sand blasting to enhance corrosion resistance and surface adhesion. Finally, we delivered 1,200 sets of products 1 day in advance, all passing the customer's strict inspection (including high-low temperature test, vibration test, and dimensional testing). Up to now, we have maintained a long-term cooperative relationship, with an annual order volume of 3,000+ sets.
