Men's Wayfarer Sunglasses

Men's Wayfarer sunglasses utilize a classic trapezoidal silhouette engineered for structural durability and high-volume commercial retail distribution. The frame architecture features reinforced bridge geometry and optimized pantoscopic tilt to fit diverse facial profiles while maintaining frame rigidity. Built for high-turnover retail and promotional markets, these frames balance impact-resistant polymer structures with precision-ground optical lenses. Production utilizes automated injection molding and CNC barrel tumbling, achieving consistent dimensional tolerances of +/- 0.1 mm across bulk production runs.

Classic Trapezoidal Geometry: Universally accepted retro-contemporary silhouette compatible with standard optical conversion and direct-to-retail packaging.

Reinforced Core-Wire Temples: Stainless steel wire cores embedded within injection-molded temples allow custom heat-adjustment and prevent structural warping under tension.

Precision 5-Barrel Metal Hinges: Industrial-grade alloy hinges secured via threaded steel screws, rated for over 15,000 open-close mechanical cycles without loosening.

Ergonomic Saddle Bridge: Integrated fixed nose pads designed for extended daily wear without localized pressure points or skin indentation.

Base-6 Curved Frame Architecture: Optimized curvature reduces peripheral optical distortion and accommodates prescription (Rx) sun-lens replacements.

Available Materials:
• TR90 (Grilamid): Memory polymer, density 1.05 g/cm3, extreme flexibility and thermal stability.
• Handmade Cellulose Acetate: Plant-based polymer, rich color depth, polishable surface finish.
• Injection Polycarbonate (PC): Cost-effective, high tensile strength, rigid structure.

Dimensional Tolerances: Lens width: 52 mm - 55 mm; Bridge width: 18 mm - 20 mm; Temple length: 140 mm - 145 mm.

Surface Finishes: Matte rubberized coating, high-gloss tumble polish, or laser-etched carbon fiber texture.

Color Matching: Pantone C and custom physical color swatches supported via masterbatch pigment compounding.

Regulatory Compliance: CE (Regulation (EU) 2016/425), UKCA (UK Regulation), FDA General Controls, ANSI Z80.3-2018 (Non-prescription sunglass optics), AS/NZS 1067.1.

Surface Coatings: Hard coating (anti-scratch, pencil hardness >= 2H), Anti-Reflective (AR) back-surface coating, Hydrophobic / Oleophobic top coat (water and grease repellent).

Drop Ball Test: Lenses withstand a 16 mm steel ball drop from 1.27 meters without fracturing.

Environmental Stress Resistance: Nickel-release compliance tested to EN 1811; sweat and cosmetic resistance verified via artificial perspiration exposure for 48 hours.

Weight Distribution: Total frame weight ranges from 22 g (TR90 configuration) to 34 g (Standard Acetate), minimizing nasal load.

Temple Tension: Calibrated spring tension applies inward pressure of 0.15 N to 0.25 N, securing the frame during movement without temple pinching.

Pantoscopic Angle: Set at 8 to 10 degrees to prevent lower frame rim contact with high cheekbones.

Retail Optical Chains: Over-the-counter sunwear collections for department stores and specialized optical retail outlets.

Outdoor & Action Sports Apparel: Companion accessories for lifestyle, streetwear, and water-sport merchandising lines.

Corporate & Promotional Programs: Custom-branded eyewear for large-scale events, corporate gifting, and promotional merchandise distributors.

PPE Secondary Sun Protection: General outdoor industrial utility where standard eye protection from glare is mandated without strict impact-shielding requirements.

Private Labeling Capabilities:
Temple Branding: Laser engraving (precise depth control for metallic or matte textures), pad printing, or color-filled hot stamping on exterior and interior temple arms.
Lens Laser Etching: Micro-laser etching of brand logos on the upper corner of the left or right sun lens without disrupting visual fields.

Tooling & Mold Engineering:
Custom mold development utilizing advanced multi-cavity steel tooling (P20 or NAK80 steel grade) derived from client-supplied STEP or IGES CAD data.
Rapid prototyping via SLA/SLS 3D printing within 7 business days for physical form-factor and ergonomic verification prior to steel cutting.

Packaging Ecosystem Integration: Full custom retail packaging solutions including collapsible paper tuck boxes, rigid magnetic closure boxes, custom dye-sublimated microfiber cleaning pouches, and embossed leatherette hard cases engineered to client retail specifications.

Injection Molding Machinery: 12 automated Haitian and Fanuc electric injection molding machines ranging from 90 to 200 tons, maintaining precise melt temperature control (+/- 1°C).

Lens Edging & Assembly: Automated CNC lens edging equipment cuts lenses to a 0.05 mm precision margin to prevent frame distortion or lens pop-out.

Quality Control Inspection Protocol:
• Incoming Material Inspection: Melt flow index (MFI) testing for raw polymer granules; spectrophotometer testing for lens tint transmission accuracy.
• In-Process QC: Dimensional checks every 100 units using digital optical comparators; hinge torque and alignment testing.
• Final AQL Inspection: Conducted in accordance with ANSI/ASQ Z1.4 (ISO 2859-1) Level II Normal sampling standards (AQL 1.0 for major defects, 2.5 for minor defects) prior to carton sealing.

Inner Protection: Each frame is enclosed in a virgin-grade PE protective sleeve, preventing micro-scratches during transit.

Bulk Master Cartons: 12 pieces per inner display box, 10 inner boxes per 5-ply double-wall corrugated master carton (120 pieces/carton). Carton burst strength rated at 275 lbs/in2.

Logistics Data: Average master carton dimensions: 60 cm x 40 cm x 35 cm; Gross weight: approximately 11 - 13 kg per carton.

Shipping Terms: FOB Ningbo/Shanghai, CIF, or DDP via partnered ocean and air freight forwarders.
