Explore production-ready stock and custom OEM/ODM frame structures engineered for optometrists, retail chains, and international distributors.
Combining proprietary hinge patents, surgical-grade material procurement, and verified compliance documentation for global brand owners.
Our patented nylon-string soft-lock and screwless articulation systems eradicate regular screw loosening. Engineered to withstand over 25,000 continuous temple flex cycles without metal fatigue.
Full-lot testing protocols matching CE, EN ISO 12312-1, FDA registration, and REACH non-toxic screening. Frame reports encompass sweat resistance, nickel-release prevention, and bridge deformation thresholds.
From Swiss EMS-Grilamid TR90 polymers and ultra-flexible Japanese beta-titanium to high-density bio-acetate sheets, we verify structural memory, thermal tolerance, and hypoallergenic coatings.
Comparative structural breakdown for B2B procurement managers selecting bulk frames.
| Substrate Material | Density & Specific Weight | Flexural Fatigue Life | Adjustment Window | Target Market Segment |
|---|---|---|---|---|
| High-Density Cellulose Acetate | 1.28 – 1.32 g/cm³ | Standard (~12,000 cycles) | High (Thermal shaping at 65°C) | Boutique fashion, luxury prescription lines |
| Swiss TR90 Memory Polymer | 1.02 – 1.05 g/cm³ | Exceptional (>50,000 cycles) | Low (Self-returning elasticity) | Athletic sports eyewear, school-age youth frames |
| ULTEM (PEI Resin) | 1.27 g/cm³ | High (>35,000 cycles) | Moderate (High thermal resistance) | Ultra-light folding frames, clinical ergonomics |
| Beta-Titanium Alloy | 4.51 g/cm³ (High Strength) | Extreme (>100,000 cycles) | High (Cold mechanical bending) | Executive minimalist rims, premium hypoallergenic |
Actionable intelligence for optical brand buyers preparing supply chains for circular compliance, intelligent production, and smart integrations.
Global environmental mandates are expediting the shift away from petroleum-based plasticizers. Forward-looking procurement programs are standardizing on bio-acetate synthesized from renewable wood pulp and ISCC-certified castor-oil derived polymers. Bulk buyers can expect stricter ESG auditing and demands for carbon-neutral packaging.
The era of rigid 5,000-piece single-SKU manufacturing is transitioning into flexible high-precision production. By leveraging multi-axis CNC routers and modular molding matrices, Shenzhen factories can now offer accelerated prototyping and agile color batching, reducing carrying costs and enabling optical retailers to test seasonal variants rapidly.
With smart audio eyewear and head-up display units penetrating mainstream markets, structural frame cavities must accommodate transducers and battery harnesses without adding bulk. We are optimizing co-injected TR90/titanium chassis specifically designed to house electronics while retaining precise lens grooving geometry.
Detailed insights into minimum order volumes, tooling lifecycles, QC standards, and cross-border logistics.
For in-stock models across our TR90, acetate, and sports collections, our minimum order quantity starts as low as 12 to 50 pieces per SKU. For bespoke OEM/ODM custom frame development requiring dedicated tooling, the baseline is generally 300 to 500 pieces per model, distributed across 2–3 seasonal colorways.
Our quality control laboratory conducts AQL Level II sampling on every batch. Mechanical assessments include bridge deformation tests (EN ISO 12870), 500-cycle temple endurance testing, barrel screw loosening torque checks, cross-cut adhesion tests for coatings, and continuous 48-hour artificial sweat immersion to rule out oxidation.
Yes. We offer laser engraving, inner-temple hot stamping, high-resolution pad printing, customized metal temple core wires, and tailored acetate laminations. Our industrial design team in France collaborates with Shenzhen engineers to turn 2D vector concepts or physical prototypes into 3D CAD models within 5 business days.
For existing warehouse inventory, dispatch occurs within 48 to 72 hours via international air couriers (FedEx, DHL, UPS). For custom OEM production runs, sample iterations take 15–20 days, followed by mass production runs of 35–45 days depending on the structural complexity of metal forming and multi-step acetate tumbling.
