ODM Custom CNC Turned Black Anodized Aluminum Lens Barrel & Housing Components - China Factory Suppliers Factories, Factory
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 the concentricity and finish quality required for advanced optical components, we employ a comprehensive 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, 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 process creates a matte black surface that absorbs stray light, preventing internal reflections within the optical system.
Laser Engraving
We offer in-house laser marking for technical specifications, focal lengths, or branding logos directly onto the curved metal surfaces.

Technical FAQ
-
QCan Sunmy handle the assembly of optical glass and metal parts?Yes. We have the capability to perform mechanical sub-assembly. However, for specific optical glass installation, please discuss your clean-room requirements with our engineering team.
-
QWhat file formats do you accept for quotation?We accept 3D files in STEP (.stp), IGES (.igs), or Parasolid (.x_t) formats, along with 2D PDF drawings specifying tolerances and threading details.
-
QHow do you ensure the anodized layer does not affect the thread fit?We calculate the coating thickness (typically 10–25 microns) during the machining stage, deliberately under-sizing threads so that after anodizing, they meet the perfect "Go/No-Go" gauge specifications.
-
QWhat is the MOQ (Minimum Order Quantity)?We support both rapid prototyping (1–5 units) for R&D verification and mass production. Contact us to discuss your specific volume needs.
-
QWhat quality inspection methods are used for optical components?All precision parts undergo CMM (Coordinate Measuring Machine) inspection to verify dimensional accuracy. We also conduct Go/No-Go gauge checks on threaded features and surface roughness measurements to ensure compliance with optical industry standards.
-
QCan you produce custom diameters and lengths for specialized optical instruments?Absolutely. Our CNC turning centers accommodate custom diameters ranging from 5mm to 300mm, with lengths tailored to your design drawings. We recommend submitting a STEP file or detailed 2D drawing to ensure accurate quoting and first-article approval.
