· Product Overview

· Core Specifications

Material Performance

• 6061-T6 Aluminum Alloy
  • Density: 2.7g/cm³ (lightweight for unobtrusive integration)
  • Tensile Strength: ≥290 MPa (rigid enough for structural load support and vibration resistance)
  • Thermal Conductivity: 167 W/m·K (excellent for heat dissipation from electronics or optical components)
  • Corrosion Resistance: Enhanced via natural anodization (scratch-proof, fade-resistant, and chemical-resistant)

Manufacturing Standards

• Certification: ISO 9001-Certified
• Key Processes: CNC Turning (cylindrical profile) → Precision Threading (external multi-groove threads) → Deburring → Natural Anodization → CMM Inspection
• Standard Parameters:
  • Outer Diameter: 50–80mm (customizable 30–100mm)
  • Overall Height: 40–60mm (customizable 25–80mm)
  • Thread Pitch: 1.5–2.0mm (optimized for secure locking)
  • Internal Bore Diameter: 45–75mm (matched to outer diameter for consistent wall thickness)
  • Dimensional Tolerance: ±0.01mm (ensures precise mating with threaded caps or components)
  • Surface Finish: Natural anodized (30–50μm thickness; low-friction and corrosion-resistant)

· Application Scenarios

• Optical & Imaging Equipment: Camera lens extension sleeves, filter adapter housings, and laser component enclosures.
• Sensor & Electronics: Proximity sensor protective sleeves, LED driver housings, and industrial control module enclosures.
• Industrial Automation: Hydraulic/pneumatic system adapters, conveyor component housings, and tool changer connection sleeves.
• DIY & Hobby Projects: Custom flashlight bodies, drone camera lens adapters, and workshop jig component housings.
• Medical & Laboratory Devices: Diagnostic instrument component sleeves, sample storage enclosures, and calibration tool housings.

· Production Process Introduction

1. Raw Material Preparation: Cut 6061-T6 aluminum bars into cylindrical blanks matching the sleeve’s overall diameter and height.
2. CNC Turning: Use high-precision CNC lathes to machine the hollow cylindrical profile and external thread base in a single setup for maximum concentricity.
3. Precision Threading: Create the multi-groove external threads with high accuracy to ensure secure, tool-free assembly.
4. Deburring & Finishing: Remove sharp edges from threads and bore surfaces to prevent component damage and ensure safe handling.
5. Natural Anodization: Submerge the sleeve in electrolytic baths to apply a durable, corrosion-resistant natural coating that enhances surface hardness.
6. Quality Inspection: Perform CMM dimensional scanning, thread fit testing, and surface finish analysis to verify compliance with design specifications.

· Packaging and Shipping Methods

• Packaging:
  • Individual Units: Sealed in anti-scratch plastic bags and labeled with thread specifications to prevent damage and ensure traceability.
  • Bulk Orders: Packed in foam-lined partitioned boxes (prevents sleeve deformation, thread damage, and mixing of sizes).
• 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.

· Frequently Asked Questions (FAQ)

• MOQ (Minimum Order Quantity): 500 pieces for standard configurations; 200 pieces for custom designs (with valid technical drawings).
• Lead Time: Standard lead time is 7–10 working days (includes CNC machining, anodization, and inspection); expedited production (5–7 working days) is available for urgent orders (additional fees apply).
• Customization Capability: Full customization is supported—adjust diameter, height, thread pitch, wall thickness, or switch to black anodization for enhanced aesthetics. We also offer internal bore modifications and laser-etched logos. Our engineering team validates designs for structural rigidity and thread fit.
