ODM Custom Precision CNC Turned Black Anodized Aluminum Lens Barrel & Optical Housing Components Manufacturer, Service
Product Description
Product Overview
Shenzhen Sunmy Hardware Co.,Ltd. specializes in the manufacturing of high-precision optical components. This product line features Precision Turned Parts specifically designed for the optical, photography, and instrument industries.
Our lens barrels and housing parts are manufactured from high-grade aluminum alloys, undergoing rigorous CNC turning and milling processes. The signature feature is our premium Black Anodized finish, which provides not only a durable, scratch-resistant surface but also essential anti-reflective properties required for high-end optical performance. Whether you need complex internal threading for lens retention or exterior knurling for grip, Sunmy delivers components that meet the exacting standards of global optical brands.
Application Scope: Camera lenses, microscope bodies, telescopic sights, laser housing, and night vision devices.
Process & Manufacturing Insights
To achieve high concentricity and superior finish quality (such as precision requirements like "0.85m/2.8ft Φ67"), we employ a rigorous multi-stage manufacturing process:
Precision CNC Turning
We utilize multi-axis turning centers to machine complex geometries with tight tolerances. This ensures that the lens barrel maintains perfect circularity and alignment, which is critical for optical clarity.
Micro-Machining & Milling
For parts requiring side holes, slots, or complex mounts (like T-shaped adapters), we integrate CNC milling to add functional features without sacrificing structural integrity.
Surface Treatment - Anodizing
After machining, parts undergo bead blasting followed by Type II or Type III Hard Black Anodizing. This creates a matte black surface that absorbs stray light, preventing ghosting and flaring.
Laser Engraving
We offer in-house laser marking for technical specifications, focal length indicators, or custom branding logos directly onto curved surfaces with high contrast precision.
