Engineered for seamless Rx glazing, tactile luxury, and modular private-label customisation. Each model incorporates validated mechanical tolerances, CNC multi-axis milling, and laboratory-tested optical ergonomics.
As a dedicated original equipment manufacturer, we eliminate the friction between conceptual design and commercial-scale production. Our facility bridges fine Italian hand-finishing traditions with cutting-edge German and Japanese precision tooling.
From sketches and 2D blueprints to fully functional 3D prototypes in 72 hours. Our engineering lab fine-tunes pantoscopic tilt, temple tension, face-form wraps, and groove depths prior to committing to mass tooling steel blocks.
Direct supply agreements with world-class substrate makers including Mazzucchelli 1849, Jinsheng bio-resins, and certified Japanese titanium smelters. We guarantee authentic chemical stability, scratch resistance, and low nickel release.
Our multi-stage 72-hour automated pumice-and-beechwood tumbling process is succeeded by hand-buffing by master craftsmen with over 15 years of bench experience. We achieve a liquid-smooth mirror finish that resists sweat degradation.
Strategic shifts in end-consumer values and international trade compliance require optical buyers to rethink vendor selection. Modern eyewear sourcing relies on four overarching technological disruptions.
Traditional petroleum-derived cellulose acetate is giving way to bio-acetates synthesized with plant-derived triethyl citrate plasticizers. Sourcing teams prioritize biodegradable certifications (ISO 14855) to align with strict EU Green Claims Directives and consumer appetite for conscious luxury.
Modern boutique retailers minimize stocking risks by deploying paired inventory strategies: offering identical frame architectures across optical prescription demo glasses and Sol sunglasses lines. This doubles floor sell-through velocity while minimizing custom tooling and lab glazing setup overheads.
B2B buyers report increasing demand for hypoallergenic pure titanium and beta-titanium chassis under 10 grams. Screwless cylinder hinges and laser-micro-welded rim-locks reduce clinic repairs and warranty claims by up to 68% compared to standard five-barrel rivet assemblies.
We test every production lot against rigorous mechanical, environmental, and chemical benchmarks to protect private label reputations on the global stage.
| Testing Metric | Industry Regulatory Standard | Factory In-House Benchmark | Buyer Safety Advantage |
|---|---|---|---|
| Bridge Deformation & Endurance | ISO 12870:2016 / Section 4.7 | < 1.0mm deflection after 500 N force | Maintains optical center pupillary alignment during long-term wearer adjustment. |
| Nickel Release Testing | EN 16128:2015 / REACH Annex XVII | < 0.1 μg/cm²/week (Zero direct contact) | Hypoallergenic guarantee preventing dermatitis and consumer skin irritations. |
| Thermal Endurance & Humidity | ANSI Z80.5 / AS/NZS 1067.1 | 60°C & 95% RH exposure for 48 Hours | Prevents acetate warpage, blistering, and delamination across tropical/arid zones. |
| Hinge Torque & Pivot Fatigue | Custom Lab Cyclic Benchmark | 25,000 continuous opening cycles | Maintains smooth, premium friction feel without loose temples or screw drop-out. |
| Optical Bevel Groove Precision | DIN 58203 Mechanical Eyewear Tolerance | ±0.05mm uniform channel depth | Flawless bench glazing for high-minus, poly, and high-index lenses without stress cracking. |
Everything opticians, supply chain directors, and brand developers need to know about bespoke OEM production parameters, order management, and international freight.
For bespoke custom acetate eyewear utilizing custom mold tooling, our standard MOQ starts at 300 pieces per model (divided across up to 3 custom colorways, 100 pcs/color). For in-stock private label cores or open-tooling models, we accommodate trial runs starting at 100 pieces to assist independent opticians in piloting new collections.
Yes. All bespoke optical models are engineered with calculated V-bevel groove depths, base-4 pantoscopic curvatures, and reinforced temple cores. This guarantees that edging labs can insert high-minus, astigmatic, and multi-focal progressive lenses without frame rim splay or lens popping.
We provide complete turnkey private labeling: temple core custom wire-filigree engraving, laser-etched hinges, hot-stamped inner temples, pad-printed demo lenses, RFID embedded barcode temple tips, alongside custom branded vegan leather cases, microfiber cleaning cloths, and FSC-certified rigid presentation boxes.
Physical prototype sampling generally takes 14 to 21 working days. Upon final approval of golden samples and color chips, mass manufacturing lead times run 45 to 65 days for acetate/TR90 series, and 60 to 75 days for complex pure titanium, multi-layer wood, or genuine buffalo horn lines requiring specialized bench curing.
All optical frames and sunglasses comply with ISO 12870, EU Medical Device Regulation (MDR 2017/745 Class I), FDA 21 CFR 801.410 impact resistance testing, and UKCA registration. We provide complete documentation, Declaration of Conformity (DoC), and drop-ball safety certificates for customs clearance.
We enforce rigorous OEM Intellectual Property protections. We execute enforceable bilateral Non-Disclosure Agreements (NDA) before accepting 2D sketches or tech packs. Custom molds and bespoke temple core dies remain the exclusive intellectual property of the commissioning client and are never showcased in public open catalogs.
