Engineered with medical-grade acetate, ultra-light TR90 polymers, and aerospace titanium. Each model supports bespoke logo engraving, customized pantone colorways, structural bridge modifications, and private label packaging architectures.
Procurement directors and brand executives navigate structural shifts across resin pricing, sustainable polymer certifications, near-zero inventory supply networks, and ergonomic customization.
Global optical retail conglomerates and independent boutique distributors are enforcing strict ESG and ISO 14001 benchmarks. Traditional petrochemical-derived diethyl phthalate plasticizers are being replaced with bio-based triethyl citrate plasticizers, rendering frames biodegradable under industrial composting setups within 115 days.
B2B contract buyers who secure certified bio-acetate billets from traceable cotton and wood pulp feedstocks mitigate impending European supply chain due diligence tariffs while commanding a 15% to 22% retail margin premium.
Traditional rigid supply networks demanding massive 2,000-piece Minimum Order Quantities (MOQs) per Stock Keeping Unit (SKU) are yielding to modular CNC production systems. Sourcing teams prioritize vendors providing high SKU versatility through low-MOQ sample runs (200-300 units) paired with rapid replenishment contracts.
This structural transformation mitigates warehouse dead-stock risks, accommodates micro-seasonal color stories, and leverages live point-of-sale sell-through metrics before initiating high-volume automated injection and milling batches.
Wholesale distribution is increasingly consolidating frame machining with digital free-form surface ophthalmic lens edging under single-roof manufacturing contracts. Brands eliminate fragmented logistical middle-steps where raw unglazed demo frames were shipped across multiple regional finishing labs.
By shifting procurement directly to OEM/ODM partners capable of integrated prescription lens glazing, blue-light vacuum coatings, and direct optical distribution, brands compress supply cycle lead times from 14 weeks down to under 21 calendar days.
High-precision multi-axis CNC cutting, morphologically calibrated pad systems, and hybrid lightweight metallics are resetting expectations across global optical trade shows from MIDO to SILMO.
Traditional barrel hinges rely on micro-threaded mechanical screws vulnerable to continuous micro-vibrations, thermal expansion cycles, and thread-stripping. Modern women's optical collections demand sleek, zero-maintenance architectural joints.
Proprietary screwless flex-lock mechanics use interlocking interlocking titanium sheets or nylon-core tensile components that absorb lateral stress without loosened screws, extending cycle life beyond 35,000 standard flex repetitions without torque degradation.
While retro cat-eye and thick-rim oval geometry remain consistent sales drivers, consumer demand has rejected heavy, pressure-inducing frames that leave unsightly nasal bridge marks. High-end manufacturing leverages 5-axis CNC diamond profile milling.
Front-rim profiles are hollow-carved to a featherweight 2.8mm thickness while preserving a dramatic 6mm visual acetate face silhouette, blending rich visual depth with featherweight ergonomics across long screen-viewing workdays.
Global export success hinges on versatile bridge seating. Fixed-bridge frames designed strictly for Caucasian cranial morphology frequently fail fit checks across East Asian, Hispanic, and African demographic groups due to bridge sliding and check-rim resting.
Engineering advancements integrate embedded adjustable beta-titanium goose-neck pad arms hidden directly within the acetate structure, enabling opticians to execute bespoke 3D adjustments in vertex distance, pantoscopic tilt, and wrap angle without compromising frame lines.
Compare raw physical tolerances, modulus elasticity, yield strengths, and finish longevity across core eyewear frame material classes prior to tooling commissioning.

Combining over six decades of heritage in optical grinding, European design studios, and high-precision Asian manufacturing infrastructure for zero-defect production.
Originating from foundational optical grinding workshops established by our Chairman in Singapore in 1960, we bring 60+ years of ophthalmic understanding into every frame. We design frames not merely as decorative fashion accessories, but as calibrated medical-grade instruments engineered for exact lens retention, optical center stabilization, and all-day ocular comfort.
Our collaborative industrial design studio in France and historical R&D center in Japan provide undeniable commercial authority. Having accumulated 21 global recognitions—including citations across the iF Design Award, Red Dot Award, and SILMO d'Or nominations—we inject market-ready aesthetic IP directly into your brand's OEM/ODM product pipeline.
Our Shenzhen engineering plants house end-to-end processing lines: multi-axis CNC acetate carving, high-pressure TR90 micro-injection molding, ultrasonic tumbling, German-engineered vacuum PVD ion-plating, micro-laser welding, and specialized cleanroom final assembly. We manage every single manufacturing layer without unregulated subcontractor leakage.
Every batch shipped leaves our facility backed by rigorous laboratory testing documentation. We supply CE Declarations of Conformity, FDA Registration documentation, full compliance with EN ISO 12870 (Ophthalmic Optics - Spectacle Frames), EN ISO 12312-1 for tinted lenses, and chemical screening adhering to EU REACH Annex XVII (nickel release, lead, and phthalate levels).
Differentiate your women's optical collections with exclusive mechanical engineering. We provide private-label access to our proprietary Screwless Hinge and Active Hinge architectures, offering functional durability and distinctive technical marketing stories that empower retail staff to convert premium frame sales effortlessly.
Streamline your enterprise procurement pipeline. A single commercial agreement with Urband opens access across women's fashion (GLOSSI), high-performance active optics (URBAND PARIS), specialized reading glasses (COUPLE), and flexible children's frames (EYELET), condensing supplier administration into a unified, reliable shipping channel.
Clear, direct technical answers covering tooling lead times, MOQ thresholds, sampling protocols, and compliance files for professional optical buyers.
For custom ODM acetate collections utilizing in-stock material acetate sheets, our standard production runs start at 300 pieces per model (divided across 2-3 custom color variations). Bespoke OEM projects requiring custom-extruded acetate pattern sheets or specialized injection tooling for TR90/titanium typically require 500 to 1,200 pieces per tooling setup to amortize initial mold development costs efficiently.
Following final 2D/3D CAD design approval, initial rapid 3D SLA functional prototypes are dispatched within 7 business days. CNC-machined physical acetate counter-samples require 18 to 25 business days. Once golden samples receive formal procurement authorization, mass production runs are completed and packed for outbound export within 45 to 60 calendar days.
All metallic and hybrid alloy components intended for skin contact conform strictly to European Standard EN 1811 (nickel release rate < 0.5 μg/cm²/week). We use advanced vacuum ion PVD sputtering techniques topped with dual-layer transparent electrophoretic polyurethane coatings, providing complete resistance to skin sweat acidity and ensuring zero contact dermatitis across sensitive wearer demographics.
Yes. We offer complete private label branding ecosystems: high-definition laser temple etching, high-relief metallic hot-stamping, core-wire pad printing, micro-inlaid end-tip brand badges, custom anti-counterfeit cleaning microfiber cloths, branded collapsible hard-cases, and FSC-certified retail outer carton packaging tailored precisely to your brand guidelines.
Every manufactured batch undergoes rigorous quality assurance checking before dispatch. We perform and document bridge endurance deformation tests, temple flex fatigue cycles (exceeding 20,000 continuous openings), thermal salt-spray exposure checks, cross-hatch coating adhesion testing, and lens retention grooving verifications, providing batch QA inspection reports with shipping documentation.
Client confidentiality and IP integrity are backed by formal non-disclosure agreements (NDAs) executed prior to file sharing. Custom tooling molds, proprietary color formulas, and bespoke hinge tooling remain the exclusive, contractually protected asset of the commissioning partner. We guarantee that proprietary client designs are never commercialized through open catalogs or trade show showcases.
