China Best Browline Glasses Frames Manufacturer & Suppliers

For ready-to-ship catalog frames from our 19 core collections, our MOQ starts at just 50 to 100 units per model with mixed colorways, supporting low-inventory testing. For custom OEM manufacturing featuring bespoke acetate sheet color formulations, private-label laser stamping, and custom tooling modifications, our standard production threshold is 300 units per colorway, or 1,200 units per mold series. We also offer prototype batch sampling (5 to 10 units) for verification prior to high-speed tooling commitment.

All metal chassis, bridges, and pad arms comply strictly with the EU REACH Annex XVII entry 27 standard for nickel release (rate <0.5 μg/cm²/week) and ISO 12870 Clause 4.7. Our electroplating process applies an intermediate palladium or white bronze barrier layer beneath the gold, ruthenium, or chrome finish, sealed by a clear cathodic electrophoresis nano-coating. Every batch is subjected to a 72-hour artificial perspiration test and a 24-hour neutral salt spray (NSS) test without showing bubbling, pitting, or green discoloration.

Yes. Our eyewire profiles are specifically engineered with an inward V-groove depth of 0.65mm ±0.03mm and an included angle of 115°, tailored for modern optical edging wheels (Santinelli, Briot, Essilor). The dual mechanical anchors securing the acetate brow cap to the metal chassis ensure that high-minus lenses (up to -10.00D with 1.67 or 1.74 high-index materials) can be glazed without splaying the bridge or twisting the pad arms. The frame holds true pantoscopic tilt (8° to 10°) and face-form wrap (4° to 6°) permanently.

Replenishment orders from our active catalog typically ship within 7 to 14 business days from our distribution nodes. For fully custom ODM/OEM programs: Rapid SLA 3D prototype models are delivered within 5 days; mold tool steel machining and pilot injection/stamping require 35 to 40 days; final production, including multi-stage tumbling, ultrasonic cleaning, hand assembly, and ISO-compliant optical inspection, requires 45 to 60 days following sample sign-off.

We integrate cold-forged German OBE or Italian Visottica-Comotec 5-barrel and 7-barrel hinges with PTFE-coated friction-damping washers to preserve smooth temple drag resistance over years of use. For extended-width collections such as Wide Guyz, we employ internally housed micro-spring box hinges that provide an additional 15° of outward flexion, preventing temple fatigue and lateral pressure against temporal bones.

Every production batch must pass ANSI Z80.5 and ISO 12870 standard inspections using an AQL 1.0 (Critical) / 2.5 (Major) statistical sampling plan. Our factory QA laboratory executes six standardized tests: 1) Bridge deformation and lens retention test; 2) 20,000-cycle temple endurance flexure; 3) Cross-cut adhesion test on lacquered parts; 4) Acetate dimensional stability in 60°C dry ovens; 5) Artificial sweat and cosmetics immersion; and 6) Drop-ball impact testing (5/8-inch steel ball dropped from 50 inches) to guarantee absolute clinical safety.

Yes. Our turnkey service includes internal fiber-laser core-wire etching, metallic foil pad printing on temple interiors, diamond-engraved endpiece emblems, and cast metal temple tips. We also manufacture custom-branded hard-shell clamshell cases, microfiber cloths with digital sublimation printing, recyclable Kraft retail boxes, and pre-printed GS1-compliant EAN/UPC barcode hangtags for streamlined retail shelf-stocking.

Our hybrid supply chain pairs high-precision manufacturing, tooling fabrication, and volume scale in China with our longstanding curation, inventory buffering, and logistics center in St. Cloud, Minnesota. North American practices can order domestic replenishment with zero customs friction, while international enterprise distributors can order direct FOB/CIF container loads from Shenzhen or Hong Kong ports, maximizing cost-per-unit margin efficiency.
