Men's Sunglasses | B2B Bulk Manufacturing & Wholesale

 

 

Engineered for optical clarity and structural durability, our men's sunglasses cater to bulk importers, retail brands, and corporate distributors. Production utilizes precision CNC machinery and automated injection molding lines, yielding consistent batch tolerances within +/-0.05 mm. Frames undergo strict stress testing to ensure joint stability, while optical lenses meet global UV protection standards. Available for private label customization (OEM) and custom mold development (ODM) with an annual manufacturing capacity exceeding 3,000,000 units.

 

 
 
 
Key Features

Optical Grade Lenses

Manufactured from TAC (Triacetate Cellulose) or polycarbonate cores with multi-layer scratch-resistant hard coats.

Structural Integrity

Reinforced multi-barrel metal hinges or integrated spring hinges tested for 20,000+ open-close cycles.

Ergonomic Fit

Optimized base curve (Base 6 to Base 8) designed for Western facial contours, minimizing wind drag and peripheral light leakage.

Coating Stability

Vacuum-deposited REVO and polarization filters bonded securely to prevent peeling or bubbling under thermal stress.

Specialty Coatings

Anti-reflective (AR) inner coating to eliminate back-glare, hydrophobic/oleophobic top coats to repel water and oil, and mirror flash finishes.

 

Frame Construction

 

 

TR90 Memory Polymer

Injected Swiss technology material. Flexible, lightweight (< 25 g total frame weight), and highly resistant to chemical and thermal degradation.

 

Handmade Cellulose Acetate

Plant-based plastic allowing rich color laminations and tumble-polished finishes. Ideal for classic and premium lifestyle collections.

 

Metal Alloys (Monel & Stainless Steel)

Electroplated using vacuum ion plating (IP plating) for corrosion resistance against sweat and saltwater exposure.

OEM / ODM Manufacturing

Prototyping & CAD Engineering

In-house industrial design team utilizing 3D stereolithography (SLA) printing and 5-axis CNC machining centers. Physical prototypes delivered within 7 to 10 days from IGES or STEP CAD files.

Precision Tooling Workshop

Dedicated mold-making facility equipped with high-speed CNC milling, wire EDM, and optical profile grinders, holding core cavity tolerances to +/-0.005 mm.

Mass Production Infrastructure

15 multi-station vertical injection molding machines for TR90 and PC frames, 8 automated metal stamping lines for alloy components, and 6 climate-controlled assembly lines maintaining an output capacity of 250,000 units monthly.

 

Quality Control & Testing Protocols

 

Optical Distortion & Prism Inspection: 100% automated diopter and prism screening to eliminate optical aberration and prevent eye strain.

 

Mechanical Stress & Fatigue Testing: Hinges undergo pneumatic cycling tests (20,000 continuous cycles) to verify screw torque retention and spring-back consistency.

 

Surface Durability Assays:
Cross-hatch tape adhesion tests on mirror and anti-reflective (AR) vacuum coatings.
48-hour neutral salt spray (NSS) corrosion testing for metallic alloy frames and barrel hinges.
High-velocity steel ball drop impact testing on lenses to verify structural resilience under ANSI Z80.3 protocols.

FAQ

 

Q: What is your standard Minimum Order Quantity (MOQ) for custom OEM production?

A: The standard MOQ is 300 pieces per model, which can be split across up to 3 different frame or lens colorways. For fully custom tooling (ODM), the MOQ starts at 1,000 pieces.

Q: How do you verify lens polarization efficiency before shipment?

A: Every production batch undergoes automated optical testing using polarization meters to confirm glare reduction exceeds 99%, alongside manual checks using polarized LCD test cards.

Q: Can you provide FDA and CE compliance test reports for our customs clearance?

A: Yes. Full compliance documentation, including EN ISO 12312-1 and FDA registration reports issued by accredited third-party labs (SGS/Intertek), is supplied with order shipments.

Q: What is the typical production lead time for repeat bulk orders?

A: Standard production lead time ranges from 25 to 35 days after sample approval and deposit receipt, depending on seasonal scheduling and custom packaging requirements.

Q: Are your metal frames nickel-free to comply with EU regulations?

A: All metal components undergo nickel-release testing to ensure compliance with the EU REACH regulation (EN 16128), preventing allergic skin reactions.

Q: Do you supply physical pre-production samples before mass manufacturing?

A: Yes. We provide pre-production physical samples for client sign-off on color matching, logo placement, and structural fit before initiating full-scale assembly.
