Product Architecture & Technical Scope

Frame Construction: Metal alloy selection, electroplating quality, hinge mechanism durability, and nose-pad adjustability determine structural fit, aesthetic profile, and daily wearability.

Lens Performance: Lens substrate composition, polarization efficiency, ultraviolet radiation blocking levels, and visible light transmission (VLT) metrics dictate regulatory compliance and visual utility.

Core Product Characteristics
Structured Metal Silhouettes: Aviator, round, square, rectangular, slim minimalist, and rimless/semi-rimless frame geometries.

Glare Reduction: Polarized lenses featuring specialized filters designed to minimize blinding horizontal light reflections from surfaces such as roads, water, and snow.

Surface Finishes: Controlled electroplating procedures providing consistent metallic finishes (e.g., gold, silver, gunmetal, matte black).

Private-Label Branding: Customized laser etching, pad printing, or metal badge application suited to specific temple and lens designs.

Retail-Ready Accessories: Coordinated protective cases, microfiber cleaning cloths, and soft pouches.

OEM & ODM Customization Routes

OEM (Original Equipment Manufacturing)
Executed strictly according to your technical design packs, blueprints, or proprietary physical samples. Complete customization of frame alloy composition, specific geometry, laser branding, and tailored packaging boxes.

ODM (Original Design Manufacturing)
Accelerate go-to-market schedules by selecting from proven metal frame catalogs. Adapt lens tint options, choose electroplating finishes, apply custom laser branding, and configure matching retail packaging solutions.

Manufacturing Facility & Quality Control

Production operations are executed within a dedicated 2,000 m² manufacturing facility equipped with 3 automated lines, CNC precision machinery, cutting equipment, and laser engraving technology. Multi-stage quality control is enforced across:

Incoming Material Audit

Alloy composition verification and raw lens inspection.

Surface Treatment Check

Plating adhesion, corrosion resistance, and visual defect sorting.

Assembly Verification

Hinge alignment, symmetry, tension, and nose-pad positioning.

Optical Testing

Polarization verification and stress-free lens seating checks.

Final Outgoing Audit

Drop-ball impact testing, accessory matching, and carton drop verification.

Compliance & Regulatory Documentation

Import requirements vary by destination market.

European Union: Manufactured in alignment with EN ISO 12312-1 standards for personal eye protection and sunglasses where applicable.

United States: Compliant with FDA guidelines and relevant federal/state safety mandates.

Note: General factory credentials do not replace model-specific test reports. Destination-specific compliance documentation must be confirmed during the quotation phase.

Frequently Asked Questions

Q: What differentiates polarized metal sunglasses from standard tinted versions?

A: Polarized lenses feature a specialized chemical filter that blocks blinding horizontal glare, whereas standard tinted lenses only reduce overall brightness. Both types require independent UV protection testing.

Q: What lens substrates are standard for metal frame construction?

A: TAC and polycarbonate (PC) are standard choices, balancing impact resistance, optical clarity, and weight.

Q: What is the standard sample development timeline?

A: Prototype development generally requires 7 to 14 days depending on custom tooling and color matching requirements.

Q: How is manufacturing quality verified prior to bulk shipment?

A: Every production batch undergoes strict multi-stage inspections covering plating integrity, hinge durability, polarization efficiency, and drop-ball testing. Detailed inspection reports are available upon request.

Q: Are export compliance documents provided with shipments?

A: Yes. Model-specific test reports, certificates of origin, and commercial shipping documentation are prepared to align with destination market customs requirements.
