Precision CNC-milled folding hinges crafted from 7075-T6 aluminum alloy with natural anodized finish—engineered for superior strength, corrosion resistance, and smooth rotational performance, ideal for industrial equipment, aerospace components, and high-end custom machinery assembly.
ParameterKey Details
Material7075-T6 Aluminum Alloy: Ultra-high tensile strength (≥540 MPa), excellent fatigue resistance, and dimensional stability; outperforms 6061 aluminum for heavy-load folding hinge applications; ensures long-term structural integrity under repeated opening/closing cycles.
Processing Capabilities3/4-axis CNC precision milling, drilling (precision pivot holes), tapping (M3–M6 threads for assembly fastening), chamfering (edge radius 0.2–0.5mm for safe handling), deburring; custom hinge profiles (butt, pivot, concealed designs); 100% CMM dimensional inspection; torque testing for rotational smoothness; assembly compatibility verification with mating components.
Tolerance & PrecisionDimensional tolerance ±0.01–±0.03mm; pivot hole concentricity ≤0.008mm (ensures smooth, wobble-free rotation); hole position tolerance ≤0.02mm; surface roughness Ra 0.4–1.6μm (reduces friction between hinge joints); consistent precision for batch assembly interchangeability.
Surface Finish & TreatmentNatural Anodizing: Thickness 8–12μm, salt spray resistance ≥500 hours (ASTM B117), scratch-resistant; enhances corrosion protection without altering the aluminum’s natural metallic luster; improves wear resistance of hinge contact surfaces; optional lubrication of pivot points for silent operation; deburred edges eliminate sharp corners to protect assembly technicians and prevent component damage.
CompatibilityFits industrial machinery enclosures, aerospace equipment access panels, heavy-duty cabinet doors, custom automation fixtures, and high-precision instrument housings; compatible with aluminum/steel mounting frames, bolted assembly systems, and gasket seals; supports both manual and automated hinge installation processes.
Application Scenarios

  • Industrial Machinery Enclosures: 7075 aluminum folding hinges—high strength withstands heavy enclosure door weight, natural anodized finish resists factory floor corrosion, smooth rotation ensures easy access to internal components for maintenance.

  • Aerospace Equipment Panels: Precision CNC-milled hinges—strict tolerance ensures alignment accuracy for aircraft access panels, lightweight 7075 alloy reduces overall equipment weight, natural anodizing meets aerospace material corrosion resistance standards.

  • Heavy-Duty Cabinet Systems: Concealed folding hinges—custom milling enables flush mounting with cabinet doors, 7075 alloy’s fatigue resistance handles frequent opening/closing, natural finish complements industrial cabinet aesthetics.

  • Custom Automation Fixtures: Pivot-style folding hinges—tailored profiles fit unique fixture designs, precise pivot hole concentricity ensures stable fixture positioning, compatible with automated assembly line integration.
