China Wholesale Designer Eyewear Factory & Exporters

Our standard production runs are structured around material processing constraints. For ready-to-ship catalog frames (such as our featured stock lines), the MOQ starts at just 50 to 100 units per model with neutral branding. For custom OEM/ODM acetate frame production requiring bespoke CNC milling, the standard MOQ is 300 pieces per model, which can be subdivided across up to 3 distinct colorways (e.g., 100 Havana Tortoise, 100 Classic Onyx, 100 Crystal Olive). For pure titanium and beta-titanium wire-drawn models, the MOQ is typically 500 units per tooling configuration due to the metallurgical extrusion runs required for specialized temple components.

We manage complete regulatory documentation for overseas customs clearance. For the United States, our optical frames and lenses comply with FDA Device Registration standards (21 CFR Part 801.410), which mandates Drop Ball Impact Testing (a 5/8-inch steel ball dropped from a height of 50 inches onto the ophthalmic lens without shattering). For the European Union, frames are manufactured under ISO 12870:2018 (Ophthalmic optics – Spectacle frames) and CE marked in accordance with the Medical Device Regulation (EU) 2017/745 (MDR) for Class I non-invasive corrective devices. We also furnish independent laboratory certificates certifying zero nickel release (<0.5 μg/cm²/week) pursuant to EN 16128.

Our agile production pipeline is divided into three distinct phases:
Phase 1 (Technical CAD & 3D Prototyping): 7 to 10 working days from 2D vector submission to high-density SLA resin 3D prototype for physical fitting review.
Phase 2 (Master Mold Tooling & Pre-Production Sample): 20 to 25 calendar days for CNC mold fabrication, hand-polishing, and color master approval.
Phase 3 (Mass Assembly & Barrel Finishing): 45 to 60 days for cellulose acetate and injection TR90; 65 to 75 days for multi-stage vacuum IP titanium. Rush protocols are available for recurring re-orders.

Absolutely. We maintain direct procurement accounts with world-class acetate houses including Mazzucchelli 1849 (Italy), Jinyu Acetate, and Jimei New Material. B2B clients can either select from our inventory of over 65 verified in-stock patterns or commission custom multi-layer laminated color acetates. For custom sheet patterns (e.g., custom tortoiseshell matrices with internal silk-screened cores), the minimum raw block extrusion order is 50 kilograms, which translates to approximately 400 to 500 optical frames.

A frame's lifespan is governed by its hinge mechanism. We offer three primary mechanical grades:
1. German OBE & Comotec Barrels: 3-barrel, 5-barrel, and 7-barrel soldered or riveted hinges engineered from nickel-silver alloy for maximum stability.
2. Redundant Spring Hinges: Internal self-lubricating flex cartridges that allow temple arms to deflect outward by an additional 15 degrees, accommodating broader facial topologies without straining the front acetate plate.
3. Screwless Titanium Hinges: Advanced interlocking cylindrical friction joints that eliminate loose screws entirely, ideal for modern architectural minimalist frames.

We support all standard international commercial terms, including FOB Shenzhen/Hong Kong, CIF, and full DDP (Delivered Duty Paid) to your logistics warehouse in the US, Canada, Australia, or the EU. Our freight management partners utilize bonded express couriers (DHL, FedEx, UPS) for priority shipments, as well as consolidated air-cargo and ocean-container shipping for high-volume orders. Our customs documentation specialists classify all goods under accurate Harmonized System (HS) codes (e.g., HS 9003.11 for plastic optical frames, HS 9003.19 for metal frames, HS 9004.10 for sunglasses) to prevent border inspection holds.
