· Product Overview
Introducing the YITECH Precision Anodized Aluminum Flange Washer Ring — a CNC-machined functional-aesthetic component engineered for structural support, visual branding, and color-coded system identification in electronics, optics, medical devices, and premium consumer hardware.
This ring delivers:
- Solid 6061-T6 aluminum construction — lightweight (2.7 g/cm³), strong (UTS 310 MPa), non-magnetic, and thermally conductive
- Six vibrant, industry-grade anodized finishes: Black, Silver (natural), Red, Gold, Purple, Blue — all Type II anodize (15 μm), with color-fastness ≥ Grade 8 (ISO 105-B02) and UV resistance (ΔE < 1.2 after 1,000 hrs QUV)
- Precision-machined geometry:
- Outer diameter: Ø25.0 ±0.01 mm
- Inner bore: Ø12.5 ±0.01 mm (H7 tolerance)
- Thickness: 3.5 ±0.02 mm
- Radial tool marks on faces (for subtle texture & light diffusion)
- Chamfered edges (0.2 mm × 45°) for safe handling and clean assembly
- Tight tolerances: ≤0.008 mm concentricity — ensures perfect centering on shafts, lenses, or PCBs
Unlike stamped steel washers or injection-molded plastic rings (prone to warping, inconsistent color, or poor fit), our flange rings offer monolithic rigidity, dimensional repeatability, and brand-ready aesthetics — even after repeated disassembly/reassembly.
Ideal for engineers building LED lighting modules, camera lens assemblies, medical device interfaces, or branded IoT enclosures where form and function must align.

· Application Scenarios
These flange washer rings excel where precise centering, visual differentiation, and structural integrity are essential:
- LED & Lighting Systems
→ Lens retention rings for COB modules (color = CCT: blue = cool white, red = warm white)
→ Heat sink interface spacers (aluminum = thermal path + EMI shield)
→ Architectural fixture bezels (purple/gold = luxury branding) - Optics & Imaging
→ Camera lens mount rings (red = IR filter, blue = UV filter)
→ Laser diode collimator housings
→ Microscope objective adapters - Medical Devices
→ Sensor housing front rings (blue = sterile field, green = calibration mode)
→ Infusion pump display bezels
→ Wearable device faceplates (ESD-safe anodize available) - Consumer Electronics
→ Smartwatch bezel accents
→ Speaker grille rings (knurled version available)
→ Drone motor caps with color-coded voltage levels - Industrial IoT & Automation
→ PLC module status rings (red = fault, green = OK — custom colors supported)
→ HMI panel decorative trim
→ Robotic end-effector identification bands
💡 Why engineers choose YITECH flange rings:
- Color = System Language — reduces assembly errors by up to 65% (client data)
- CNC from billet = zero warpage — unlike stamped or cast alternatives
- H7 bore = precision fit — no play on shafts or optics
- Custom colors in 5 days — no MOQ for hue changes
· Production Process Introduction
We follow a rigorous, traceable workflow for high-precision aesthetic hardware:
- Raw Material Verification
Certified 6061-T6 aluminum bar stock; hardness 95 HB minimum. - CNC Turning (High-Precision Lathe)
- Facing, centering, rough/finish turning of OD/ID/thickness
- Radial tool-path finishing on faces for uniform texture
- Edge chamfering (0.2 mm × 45°) for safety and aesthetics
- No secondary operations needed — all features in one setup
- Deburring & Cleaning
Thermal deburring + ultrasonic cleaning (IPA/water) → removes micro-burrs at bore edges. - Anodizing (Type II, 15 μm)
- Pre-treatment: Alkaline clean → etch → desmut
- Anodizing: Sulfuric acid bath, 15 μm thickness
- Dyeing: High-fastness organic pigments (all 6 colors validated for lightfastness)
- Sealing: Hot DI water (ASTM B580)
- Bore interior masked to ensure clean, uncoated surface for slip-fit assembly
- Laser Marking (Optional)
Part number, orientation arrow, or QR code (on outer edge — invisible in assembly) - Quality Assurance
