· Product Overview

· Core Specifications

• Material: 6061-T6 Aluminum Alloy
  • Density: 2.7g/cm³ (lightweight to reduce drive load)
  • Tensile Strength: ≥290 MPa (rigid for high-speed operation)
  • Thermal Conductivity: 167 W/m·K (excellent for heat dissipation)
  • Corrosion Resistance: Enhanced via natural anodization (scratch-proof and fade-resistant)
• Manufacturing Standard: ISO 9001-Certified
  • Key Processes: 5-Axis CNC Milling (blade profile + hub) → Precision Drilling (keyway bore) → Deburring → Natural Anodization → CMM Inspection
  • Standard Parameters:
    • Overall Diameter: 100–200mm (customizable 50–300mm)
    • Central Hub Bore: 10–15mm (with 2mm keyway for shaft locking)
    • Blade Thickness: 2–3mm (optimized for rigidity and efficiency)
    • Dimensional Tolerance: ±0.02mm (ensures balanced rotation at high speeds)
  • Surface Finish: Natural anodized (50–80μm thickness; corrosion-resistant and smooth for low turbulence)

· Application Scenarios

• Industrial Cooling: Heat exchanger fans, CNC spindle cooling systems, and 3D printer hotend cooling.
• Fluid Agitation: Chemical mixing tanks, aquarium circulation pumps, and wastewater treatment aerators.
• Marine & Hobby Use: Small boat propulsion propellers, RC boat drive systems, and model ship thrusters.
• HVAC & Ventilation: Compact fan units for server racks, workshop exhaust systems, and portable cooling devices.

· Production Process Introduction

1. Raw Material Preparation: Cut 6061-T6 aluminum billets to match the impeller’s overall diameter and thickness.
2. 5-Axis CNC Milling: Use precision 5-axis mills to machine the aerodynamic blade profile and central hub in a single setup for maximum balance and accuracy.
3. Keyway Bore Drilling: Create the central bore and keyway to ensure secure shaft locking and torque transfer.
4. Deburring & Finishing: Remove sharp edges from blades and hub to reduce turbulence and ensure safe handling.
5. Natural Anodization: Submerge the impeller in electrolytic baths to enhance corrosion resistance and surface durability.
6. Balance & Quality Inspection: Perform dynamic balance testing and CMM dimensional scanning to verify high-speed stability and tolerance compliance.

· Packaging and Shipping Methods

• Packaging:
  • Individual Units: Wrapped in anti-scratch foam padding and sealed in moisture-proof plastic bags to protect the anodized finish.
  • Bulk Orders: Packed in foam-lined cardboard boxes with dividers to prevent blade deformation during transit.
• Shipping Options:
  • Express Delivery (DHL/FedEx): 3–5 business days for prototype or small-quantity orders.
  • Air Freight: 7–10 business days for medium-batch production runs.
  • Sea Freight: 20–25 business days for large-volume bulk orders.All shipments include full tracking and damage insurance.
