Engineered with sub-millimeter magnetic dock integration, aspherical precision optics, and aero-grade titanium alloys. Review our core production benchmarks ready for bespoke private-label manufacturing.
The standard failure mode of commercial clip-on spectacles lies in mechanical clip fatigue, magnetic decoupling under lateral torque, and aesthetic bulkiness. In our custom OEM manufacturing protocol, magnetic clip eyewear transcends basic add-on accessories by operating as a unified biomechanical system.
We deploy micro-encapsulated NdFeB (Neodymium Iron Boron) permanent magnets rated at N50 to N52 thermal resistance grades. These magnets are integrated via high-precision CNC micro-milling directly into the temporal lugs and bridge junctions of the chassis, shielded with 24K gold or physical vapor deposition (PVD) anti-corrosive multi-layer plating.
| Component | OEM Enterprise Grade | Generic Wholesale Grade |
|---|---|---|
| Magnet Class | N52 NdFeB (Nickel+PVD Capped) | N35 Industrial (Exposed/Epoxy) |
| Extraction Force | 4.8 N ± 0.3 N (Optimized retention) | < 2.2 N (Prone to detachment) |
| Chassis Substrate | Beta-Titanium / Block Bio-Acetate | Recycled PC / Zinc Alloy |
| Salt Spray Resistance | 120 Hours Continuous (ISO 9227) | 24 Hours (Oxidation risks) |
| Optical Alignment | Zero-Prism Parallel Offset (<0.05°) | Noticeable Prism / Parallax Distortion |
Independent optical practices and high-tier brands cannot afford inventory commoditization. Our OEM manufacturing pipeline delivers differentiated, high-margin eyewear platforms tailored to demanding clinical standards.
From 2D technical sketches to functional 3D photopolymer mockups within 72 hours. Our Design for Manufacturing (DFM) team fine-tunes temple weight distributions, magnetic draft angles, and pantoscopic tilt for immediate clinical satisfaction.
Every production batch complies with global regulatory standards: FDA Registered (21 CFR), CE Certified under Medical Devices Regulation (EU) 2017/745, and rigorously evaluated against ISO 12870 mechanical strength parameters.
Protect your cash flow. We offer universal base-chassis platforms that accept interchangeable magnetic add-ons: Cat.3 polarized sun clips, high-contrast driving filters, and 420nm digital blue-blockers on a single base frame SKU.
Key technological inflections shaping bulk purchase specifications and procurement decisions over the next five years.
Global optical retailers are phasing out petrochemical plastics. Procurement contracts are shifting rapidly toward bio-acetate (cotton linters & plasticizers derived from bio-sources, DIN CERTCO certified) coupled with recycled titanium rims, demanding lead-free soldering and nickel-free coatings.
End consumers demand 3-in-1 convenience. Optical brands are shifting catalog allocations from single-purpose frames to 4-clip sets (Polarized Grey + High-Contrast Amber Driving + 3D Display + 450nm Gaming Amber), packaged in customized compact travel cassettes.
Next-generation OEM clip frames integrate low-profile magnetic docks prepared for micro-hearing assist attachments and Heads-Up Display (HUD) modules. Strategic suppliers must hold internal tolerances under ±0.015mm to guarantee electronic contact pin alignment.
Direct technical and operational answers to address common engineering, compliance, and supply chain queries.
We solve galvanic corrosion through dual-step passivation. First, all N52 magnets receive an electroless Nickel-Copper-Nickel (Ni-Cu-Ni) triple coating topped with a PVD titanium vacuum finish. Second, magnets are seated in CNC-undercut mechanical slots and secured with aerospace-grade anaerobic polymer adhesives, resisting 120 hours of salt spray and over 15kgf push-out shear force.
No. Our magnetic flux leakage calculations ensure the magnetic field drops below 0.5 Gauss at a distance of 10mm from the chassis. This makes them entirely compliant with international standards regarding cardiac pacemakers and ensures no demagnetization occurs to payment cards stored in standard pocket proximities.
For custom acetate and titanium frames with proprietary magnetic clip tooling, standard MOQ is 300 units per model, split across up to 3 colorways (100 units/color). For stock base frames requiring bespoke custom logo engraving and private-label packaging suites, low-volume trial runs start at 100 units.
Yes. The clip-on bridge is engineered with a deliberate 0.6mm anterior offset tolerance. This ensures that even high minus prescriptions (up to -6.00D with standard base curves of 4.00 or lower) mounted into the optical chassis will not contact the interior surface of the polarized clip, eliminating surface scratch hazards.
All OEM consignments are released with complete Certificate of Conformity (CoC) dossiers: ANSI Z80.3 (US), EN ISO 12312-1 (EU), and AS/NZS 1067.1 (AU/NZ) optical clarity reports. UV400 spectral analysis charts and Drop Ball Test (21 CFR 801.410) impact certification are provided with every batch.
We provide multiple high-end finishing methods: high-precision laser ablation on the titanium inner core or clip brow-bar, micro-injected metal foil logos embedded inside acetate temples, hot stamping, and silk-screen pad printing using non-toxic German Marabu inks.
