Component Specification: Frames & Lenses

Frame Polymer Options
Molded frame performance depends on the raw polymer grade, wall thickness, and structural design:

Polycarbonate (PC): Cost-effective, high impact resistance, and well-suited for high-volume injection-molded commercial collections.

TR90 (Grilamid): Ultra-lightweight, high flexibility, and excellent memory retention, ideal for active-lifestyle and lightweight everyday ranges.

Cellulose Acetate: Premium cotton-derived material offering rich color depth, hand-polished finishes, and suitability for high-end boutique collections.

Note: Material availability varies by model SKU. Confirm your target SKU and mechanical requirements before bulk sampling.

Polarized Lens Performance & Optical Standards
Polarization Filter: Effectively blocks horizontal glare reflected from water, roads, and smooth surfaces, enhancing visual comfort in high-glare environments.

Material Substrates: TAC (Triacetate Cellulose) and alternative optical substrates selected for clarity and cost-performance balance.

UV Protection: Polarization does not equate to UV protection. All custom production runs can be configured to meet UV400 standards, supported by independent laboratory test reports upon request.

Optical Quality: Lenses are inspected for optical clarity, prism imbalance tolerances, and surface defect elimination.

Manufacturing & Production Infrastructure

Facility Scale: 2,000 m² dedicated eyewear manufacturing plant with standardized production lines.

Core Machinery: High-precision injection molding machines, CNC machining centers, automatic cutting equipment, and high-speed laser marking systems.

Process Control: In-house handling from raw polymer injection, tumbling, and frame polishing to optical assembly and final packaging.

Capacity & Flexibility: Scalable output designed to support seasonal inventory replenishment, urgent promotional programs, and long-term brand supply agreements.

OEM & ODM Customization Services

OEM: Customizing Existing Frameworks

For brands looking to adapt established tooling with proprietary branding:

Apply custom client logos via temple printing or laser marking.

Select custom frame colors via Pantone (PMS) matching.

Pair frames with specified lens tints and gradient options.

Integrate bespoke packaging suites (pouches, hard cases, cleaning cloths, branded outer boxes).

ODM: Full Product Development from Brief

For importers and brand owners developing proprietary collections:

Submit design sketches, 3D CAD files, or physical reference samples.

Our engineering team evaluates tooling feasibility, mold flow, structural integrity, and target cost parameters.

Prototype sampling and pre-production sample (PPS) sign-off prior to mass manufacturing.

Quality Control & Inspection Workflow

To minimize shipment discrepancies and ensure consistent bulk quality, our factory QC protocol follows strict operational checkpoints:

Incoming Material Inspection: Raw polymer pellets, metal components, and lens sheets are checked for physical and chemical compliance.

Molding & Machining QC: Monitoring injection pressure, temperature control, flash removal, and dimensional accuracy against approved CAD drawings.

Assembly & Functional Testing: Testing hinge tension, temple alignment symmetry, opening/closing cycles, and lens retention security.

Optical & Surface Verification: Inspecting lenses for micro-scratches, coating adhesion, and verifying polarization axis alignment.

Pre-Shipment Inspection (AQL Standard): Final check of carton drop tests, barcode readability, packaging integrity, and ordered quantities.

Commercial Applications & Target Channels

Eyewear Brands & Private Labels: Build cohesive retail collections with precise color coordination, custom packaging, and verified optical specs.

Importers & Regional Wholesalers: Source reliable, volume-scalable models designed for predictable inventory turnover and retail distribution.

Fashion & Lifestyle Retailers: Rapid response to seasonal trends through flexible frame shapes, finishes, and trend-aligned color palettes.

Corporate Gifting & Promotions: Custom-branded promotional sunglasses manufactured to strict corporate identity and budget requirements.

FAQ

Q: What is the minimum order quantity (MOQ) for plastic polarized sunglasses?

A: MOQ depends entirely on the selected frame mold, material, and customization complexity. While select catalog items (such as standard TR90 models) start at 200 pieces, custom injection molds or specialized acetate runs require distinct thresholds. Contact our sales desk with your SKU of interest for exact terms.

Q: Can I request physical samples before placing a bulk order?

A: Yes. We support pre-production sampling. Sample fees and freight terms vary depending on whether you require standard catalog pieces or customized logo development.

Q: How do you verify polarization and UV protection?

A: We provide product-specific technical data and coordinate third-party laboratory testing (such as CE, FDA, or ANSI compliance documentation) upon request, ensuring test reports match your specific target market regulations.

Q: What files do you require for custom logo production?

A: Please provide vector artwork in AI, EPS, or PDF format, along with exact Pantone color codes and specified placement coordinates (e.g., left/right outer temple).

Q: What are your standard payment terms for bulk orders?

A: Standard export terms typically involve a 30% deposit via T/T upon order confirmation, with the remaining 70% balance settled against inspection reports or Bill of Lading copy. Letter of Credit (L/C) terms can be discussed for qualified large-scale orders.
