Source plastic frame sunglasses for eyewear collections, retail programs, or private label projects. This catalog covers manufactured eyewear in injection-molded polymers, TR90, and cellulose acetate, supported by customized manufacturing and OEM/ODM services for businesses developing proprietary eyewear lines.

Select from existing production models or configure frame colors, lens specifications, private label branding, and packaging to match specific market and channel requirements.

Material Selection: Choose the Right Polymer

Material	Key Mechanical & Aesthetic Characteristics	Primary Procurement Considerations
Injection-Molded Plastic (PC / Propionate)	Supports complex mold designs, high-volume manufacturing, and diverse color injection.	Verify exact polymer grade, wall thickness, frame weight, and structural rigidity.
TR90 (Grilamid)	Lightweight thermoplastic with exceptional memory flex, high impact resistance, and fatigue tolerance.	Confirm specific material density, heat distortion threshold, and finished-frame recovery performance.
Cellulose Acetate	Plant-based polymer ideal for rich layered colors, deep hand-polishing, and wire-core temples.	Confirm sheet stock source, shrinking tolerance, tumbling duration, and model-specific minimum batch requirements.

Product Specifications & Customization Parameters

A precise commercial quotation requires clear technical definition. Review the following configurable parameters:

Frame & Construction
Front Geometry & Thickness: Bridge width, lens eye size, rim profile, and overall face curvature.

Hinge Integration: Barrel hinges, spring hinges, or rivet-secured options.

Temple Construction: Core wire presence, temple shaping, and tip finishing.

Surface Treatment: Gloss tumble, hand polish, rubberized soft-touch coating, or laser etching.

Lens Configurations
Lens selection must align with the intended end-user environment and regional performance standards:

Materials: Polycarbonate (PC), TAC (Triacetate Cellulose), or CR-39.

Optical Metrics: Base curve, nominal thickness, and Visible Light Transmittance (VLT) categories.

Functional Treatments: UV400 protection (blocking wavelengths up to 400nm), polarized filter integration, anti-reflective (AR) back-coating, or flash mirror gradients.

Compliance, Safety & Regulatory Standards

Eyewear distribution requires strict alignment with regional product safety regulations.

General Use Standards: Uncorrected general-use sunglasses are typically evaluated against international benchmarks such as ISO 12312-1 to ensure structural integrity and safe optical performance.

UV Protection Verification: Lenses marketed with UV400 protection must be backed by laboratory spectrophotometer testing confirming complete blockage of ultraviolet rays up to 400nm. A darker lens tint does not inherently indicate superior UV protection.

Impact Resistance: Regional markets (such as North America or Europe) maintain specific drop-ball or impact-resistance test requirements for lenses and frames depending on the distribution channel. Test reports and documentation can be reviewed against specific project requirements upon request.

Manufacturing Capabilities: OEM and ODM Solutions

End-to-end manufacturing workflows support brands scaling their eyewear lines.

OEM (Original Equipment Manufacturing)

Starting Point: Technical drawings, 3D CAD files, design specifications, or approved physical counter-samples.

Process: Engineering review, tooling feasibility analysis, prototype sampling, sample sign-off, and mass production.

ODM (Original Design Manufacturing)

Starting Point: Selection from an extensive catalog of proprietary frame designs or trend-driven development briefs.
Process: Model selection, colorway and lens tuning, custom branding application, and rapid sample prototyping.

Quality Control & Assurance Milestones

Bulk eyewear manufacturing requires systematic verification at multiple production milestones:

Material & Tooling Audit: Verifying polymer pellets, color masterbatch accuracy, and mold cavity dimensions.

In-Process Molding Inspection: Monitoring frame symmetry, bridge alignment, diagonal measurements, and freedom from surface flash or flow lines.

Mechanical Testing: Checking hinge torque endurance, spring-tension resilience, and temple alignment tolerance.

Lens & Assembly Verification: Ensuring secure lens retention within the bezel groove, absence of optical distortion caused by frame pinching, and verification of stated UV/polarization performance.

Pre-Shipment Inspection (AQL): Final inspections executed in accordance with agreed Acceptable Quality Limit (AQL) standards covering carton drop tests, barcode legibility, and packaging integrity.

Frequently Asked Questions

Q: What is the Minimum Order Quantity (MOQ) for wholesale plastic sunglasses?

A: MOQ varies depending on whether you select existing ready-to-produce catalog items or request custom injection colors and private label tooling. Standard stock styles and custom runs have different thresholds. Submit target volumes for exact verification.

Q: Can existing styles be ordered without modifying structural designs?

A: Yes. Selecting from established models eliminates tooling investments and accelerates delivery schedules. Color combinations, lens tints, and branding can still be customized.

Q: How do injection-molded plastic and TR90 frames differ in performance?

A: While both fall under polymer eyewear, TR90 offers superior flexibility, low weight, and memory-shape recovery under stress, making it ideal for active lifestyle collections. Standard injection plastics provide broader rigid geometry options at alternative cost structures.

Q: Are supporting eyewear accessories available?

A: Yes. Matching accessories, including hard cases, folding cases, microfiber pouches, and custom-printed cleaning cloths, can be bundled directly with sunglass orders.
