Polarized Sunglasses

Product Overview
 

Engineered for industrial safety, outdoor sports, and retail distribution, our polarized sunglasses eliminate horizontal glare caused by reflective surfaces such as water, snow, and asphalt. Manufactured in our 12,000-square-meter ISO 9001-certified optical facility-equipped with 25 precision injection lines and dedicated optical lamination cleanrooms-each production batch undergoes rigorous drop-ball testing, salt-spray corrosion resistance tests, and digital spectrophotometer UV transmission checks. We supply global B2B importers, retail brand owners, and safety equipment distributors with fully customizable OEM and ODM manufacturing runs, backed by complete third-party compliance documentation and scalable production capacity of up to 300,000 pairs monthly.

Manufacturing & Quality Control

 

Precision Injection Molding: 25 Haitian injection molding machines utilizing hot-runner molds to prevent sink marks, gas lines, and internal structural stress in TR90 frames.

 

Lens Polarization Lamination: Automated optical film alignment lines ensure vertical axis tolerance strictly within +/- 0.5 degrees.

 

Vacuum Coating Deposition: Hard-coat and anti-reflective (AR) vacuum chambers applying uniform scratch-resistant layers on both lens surfaces.

 

Rigorous Quality Assurance Protocols:
• Drop Ball Test: 16g steel ball dropped from 1.27 meters onto lenses to verify impact-resistant integrity.
• Polarization Axis Test: Digital spectrometer verification of light extinction efficiency across every batch.
• Hinge Fatigue Test: Mechanical test arms cycle temple arms 25,000 times to test long-term tension retention.
• AQL 2.5 Sampling: Final outgoing quality inspection conducted per ISO 2859-1 standards prior to master carton sealing.

FAQ

 

Q: What is the minimum order quantity (MOQ) for custom private-label branding?

A: The standard MOQ for custom logo printing on temples or lenses is 300 pieces per SKU, which can be split across up to 3 lens/frame color variations. For custom Pantone injection colors and custom retail packaging boxes, the MOQ starts at 500 pieces.

Q: How do you verify the authenticity and performance of the polarization?

A: Every production lot is tested using a polarized light meter and digital spectrophotometer. We provide factory test reports confirming a minimum 99% extinction rate and supply testing cards with each shipment for immediate retail verification.

Q: What international optical standards do your sunglasses meet?

A: Our products comply with EN ISO 12312-1 (Europe), ANSI Z80.3 (United States), and AS/NZS 1067.1 (Australia/New Zealand). Full test reports issued by independent third-party laboratories (SGS and Intertek) are available upon request.

Q: Can you provide pre-production samples before confirming bulk manufacturing?

A: Yes. We supply physical pre-production samples featuring your custom logo and color specifications within 7 to 10 days. Mass production begins strictly after receiving written sample sign-off or digital approval photos.

Q: What is your standard production lead time for wholesale orders?

A: Standard production runs take 25 to 35 calendar days following deposit confirmation and packaging artwork approval. Expedited production schedules can be arranged for recurring contract orders and framework agreements.

Q: What warranty terms do you offer for manufacturing defects?

A: We offer a 12-month manufacturing defect warranty covering optical coating delamination, frame hinge structural failure, and polarization layer separation under normal commercial use conditions. Defective units are replaced in subsequent shipments.
