OEM/ODM Oversized Sunglasses Wholesale Factory & Supplier

Mass Distribution & Bridge Physics

Oversized silhouettes (56mm to 64mm eye sizes) historically suffer from gravitational descent and nose bridge pinching. Our factory implements high-density CNC routing that varies rim thickness from 6.0mm along the temporal ridge down to 2.8mm at the lower eyewire, shifting the center of gravity backwards towards the mastoid bone.

• 35% reduction in nasal bridge load
• Balanced pantoscopic tilt (8° - 11°)

Decentered Optical Decalibration

Large frame apertures cause substantial prismatic displacement if lenses are cut along geometric centers rather than pupil centers. We calibrate our OEM nylon and CR-39 polar molds with a built-in optical center compensation factor, preventing peripheral chromatic aberration and distortion in high-wrap styles.

• Zero-distortion Base Curve 2.0 to 6.0
• EN ISO 12312-1:2022 Certified

Multi-Barrel Structural Anchors

Oversized temples exert excessive torque on hinge assemblies. Our production standard replaces conventional 3-barrel friction pins with custom heat-embedded 5-barrel and 7-barrel nickel-silver hinges bonded through ultrasonic fusing directly into the wire core, passing 25,000-cycle temple flexion trials.

• Teflon-coated locking screws
• Zero play hinge tolerance (<0.02mm)

1. Bio-Based Acetates & Carbon Neutrality

Global regulatory shifts (such as EU Corporate Sustainability Due Diligence) are accelerating the demand for non-phthalate plasticizers. Procurement directors are moving from standard petro-acetate to bio-cellulose acetate derived from FSC-certified cotton seed fibers and wood pulp, achieving >68% bio-carbon content while retaining optical polish brilliance.

2. Hybrid Material Laminations

The convergence of architectural aesthetics and lightweight ergonomics has triggered massive B2B orders for metal-rimmed acetate channels and TR90 inner skeleton wraps. Laser-sintered titanium core wires encapsulated inside translucent oversized silhouettes deliver distinct multi-depth refraction that mass-market injection molds cannot match.

3. Rx-Capable Sunglass Engineering

Oversized styles are no longer limited to vanity non-prescription lenses. Independent optical retailers are demanding OEM sunglasses engineered with step-bevel grooves and 4.0-base curvetures capable of accommodating high-minus (-4.00D to -6.00D) ophthalmic progressive and single-vision surfacing without lens pop-out.

Full In-House Prototyping

From CAD rendering and 3D resin mockups to functional brass mold development within 7 to 10 working days, radically shortening your time-to-market.

Agile Low MOQ Flexibility

We respect growing collections. While conventional plants enforce 1,200+ units, our flexible line setups support custom colorways starting at just 300 pieces per SKU.

Global Compliance Ready

Every frame production batch is pre-tested for nickel-release compliance (EN 16128), California Prop 65, FDA Registration (Device Class 1), and CE conformity.

Direct B2B Distribution Logistics

End-to-end overseas logistics assistance including duty drawback handling, secure carton palletizing, and door-to-door dropshipping for key distribution hubs.
