Explore our precision-crafted wholesale frame lineup engineered for durability, optical clarity, and modern ergonomic compliance.
The global eyewear landscape is experiencing a structural evolution. According to modern industry analytics, the wholesale market for Men's Sunglasses is transitioning rapidly from traditional consumer-grade retail toward high-value, tech-infused, and material-optimized optical solutions. Modern male consumers no longer view sunglasses solely as seasonal UV-blocking accessories; they demand multi-scenario performance, bio-based sustainability, high structural resilience, and architectural frame aesthetics.
For international distributors, optical chain stores, brand owners, and e-commerce aggregators, identifying a robust Wholesale Men's Sunglasses Manufacturer & Factory is the single most critical factor in securing profit margins, brand equity, and supply continuity. Navigating macro-economic headwinds requires partnering with manufacturing nodes capable of delivering raw material traceability, agile turnarounds, precision CAD engineering, and automated production consistency.
Modern male frame ergonomics necessitate broader temple spreads, reinforced 5-barrel custom hinges, and precise pantoscopic tilt angles. Our engineering team recalibrates frame weight distribution to eliminate facial contact fatigue across extended wear.
Global environmental mandates require eco-friendly material adoption. We specialize in organic cellulose acetate derived from cotton fibers and wood pulp, entirely free of phthalates, guaranteeing non-allergenic skin contact and biodegradability.
Incorporating TAC polarized filters, Nylon anti-shatter lenses, and multi-layer hydrophobic Anti-Reflective (AR) optical coatings that provide complete UV400 coverage while eliminating high-glare back reflected light.
Yintai Eyewear is a premier optical manufacturer based in Shenzhen, Guangdong Province, China. Over 15 years of dedicated engineering evolution has elevated Yintai from an advanced workshop into a globally trusted enterprise integrating technological research and development, high-precision automated manufacturing, and end-to-end B2B supply chain solutions.
Operating within our modern industrial ecosystem at the Fuji Land Building industrial park, our production floor is equipped with 5-axis fully automated CNC machining centers, automated high-pressure hydraulic presses, Class 10,000 cleanroom lens assembly units, and multi-stage ultrasonic tumbling and polishing lines. This state-of-the-art infrastructure ensures absolute batch consistency, rapid prototyping turnaround, and strict tolerance management across complex frame geometries.
Our modern factory spans over 5,000 square meters. Featuring 5-axis CNC machining, automated wire-core insertion equipment, and cleanroom optical fitting environments, our facility provides stable foundations for volume orders without quality degradation.
Backbone strength lies in our workforce of over 200 dedicated professionals, including a 10-member technical R&D engineering team specialized in structural mechanics, 3D CAD modeling, custom hinge integration, and ergonomic calibration.
From raw block acetate cutting and custom titanium molding to precision electroplating, tumble polishing, laser marking, and final assembly—we control the complete value chain. This yields superior cost predictability and expedited shipping cycles.

Our integrated QC workflow encompasses IQC (Incoming Raw Material Inspection), IPQC (In-Process Digital Checks), and FQC (Final Quality Control). Over 99% first-pass yield rate verified under ISO9001 protocols, with CE mark, FDA registration, and RoHS material safety certifications.
Frame hinges undergo continuous mechanical tension tests up to 20,000 open-close cycles. Optical bridge stability is tested against salt spray environment corrosion for 72 consecutive hours without surface pitting or degradation.
Transform conceptual sketches into 3D CAD models within 48 hours. Physical sample engineering completed within 7 to 10 days. Mass manufacturing completed with reliable scaling, supporting custom branding, specialized hardware, and bespoke packaging.
Subtle architectural geometries, polished dark acetate, transparent crystal colorways, and sleek metal rivets tailored for metropolitan working environments. Designed for smooth transition between indoor computer screens and outdoor business commutes.
Engineered with polarized category-3 lenses, anti-reflective interior coatings, light-weight TR90/Titanium hybrid temples, and non-slip rubber nosepads. Perfectly tuned for automotive driving, yachting, golf, and aviation operations.
Thick-rimmed 8mm micro-milled acetate profiles featuring hand-carved arrow or cross rivets, custom core wire engraving, and classical tortoiseshell motifs designed for boutique retail chains and high-margin fashion labels.
Our baseline MOQ for custom OEM/ODM acetate frame production typically starts at 300 to 500 pieces per model/colorway, depending on material complexity and mold requirements. For ready-to-ship wholesale stock models with laser-etched custom logos, we support lower order thresholds to assist brands with fast market testing.
Every production batch is tested in-house and third-party certified. Lenses meet ISO 12312-1 and ANSI Z80.3 impact standards. Frame materials undergo toxicological screening for nickel release (EN 16128) and phthalate restrictions under RoHS. Detailed test reports and CE compliance declarations are provided with commercial documentation.
Rapid 3D CAD modeling is delivered within 48 to 72 hours. Prototype physical sample production takes approximately 10 to 14 days. Once pre-production samples receive client sign-off, mass production lead time typically ranges between 35 to 45 business days, backed by our monthly capacity of over 20,000 units.
Yes. We maintain direct sourcing channels with premium acetate suppliers globally, including Mazzucchelli 1849 (Italy) and Jiaming Acetate. We can also integrate client-specified titanium bridges, OBE spring hinges, or specialized photochromic lenses into custom production workflows.
