2. Manufacturing Process

• Core Processing Method: CNC metal spinning forming combined with wiredrawing finishing, followed by secondary machining for precision. Equipment includes CNC metal spinning lathe and fully automatic wiredrawing machine.
  
  • CNC spinning spindle speed: 1000–1500 r/min
    
  • Roller feed rate: 8–12 mm/s
    
  • Single pass deformation: 0.3–0.5 mm
    
  • Wall thickness uniformity deviation: ≤ ±0.08 mm
    
  • Wiredrawing: axial direction, 15–20 m/min, belt grit 1200#
    
• Raw Material Preparation: 6063 aluminum alloy sheets undergo alkaline degreasing (50–60°C, NaOH 4–6%, 8–12 min), water neutralization, drying (80–100°C, 15–20 min), and flattening (flatness deviation ≤0.2 mm/m) to remove oil, oxide scale, and surface scratches.
  
• CNC Process Control: CNC metal spinning lathe with G-code programming defines spinning paths. Real-time diameter and height data acquisition at 12 Hz for closed-loop control:
  • Ø615 mm tolerance ≤ ±0.4 mm
  • H373 mm tolerance ≤ ±0.3 mm
  • End faces precision-turned on CNC lathe; perpendicularity error ≤ 0.1 mm

• Post-Processing: Mechanical deburring at 3200 r/min with 1500# abrasive wheel. Compressed air cleaning removes residual debris, followed by dimensional recheck and surface quality inspection per core parameters.
  

3. Quality Control

• Standards: ISO 9001:2015 quality management system, GB/T 3880.1-2012 aluminum building profiles standard. Full-process quality control from raw material intake to finished product delivery.
  
• Raw Material Inspection:
  
  • Spectrometer analysis: element deviation ≤ ±0.05% (Mg 0.45–0.9%, Si 0.2–0.6%)
    
  • Hardness test: ≥60 HB
    
  • Surface check: visual + 20× magnifier, no cracks, inclusions, dents
    
• Process Inspection:
  
  • Spinning Form Accuracy: curvature template, adherence ≥98%
    
  • Dimensional Inspection: CMM (±0.005 mm) for Ø615 mm, H373 mm, 2.0 mm thickness
    
  • Wiredrawing Inspection: visual uniformity, Ra measured with roughness tester
    
  • Edge Inspection: no burrs, sharp edges; chamfer R ≥ 1.5 mm
    
• Final Inspection: Sampling per GB/T 2828.1-2012, AQL 2.5. Items include dimensional verification, material recheck, surface, appearance, and assembly fit. Products are tagged with traceability codes including raw material batch, equipment, and inspector information.
