Manufacturing solutions for custom plastic sunglasses, covering private-label customization of existing injection-molded frame styles as well as full OEM/ODM development from technical drawings or physical reference samples.

Production capabilities encompass Polycarbonate (PC), TR90 memory polymer, and Cellulose Acetate frames, paired with compliant optical-grade Polycarbonate (PC) or Triacetate Cellulose (TAC) lenses. Structural configurations, material formulations, optical specifications, and retail packaging are engineered to align with target cost structures and destination market regulations.

Frame Material Performance & Selection

Material Category	Core Technical Characteristics	Recommended Application
PC (Polycarbonate)	Rigid, high impact resistance, smooth surface gloss; supports solid, transparent, and gradient spray finishes.	Fashion-forward retail collections, promotional giveaways, cost-sensitive wholesale programs.
TR90 (Grilamid)	Ultra-lightweight thermoplastic memory polymer, high flexural elasticity, resistant to thermal deformation under normal use.	Active lifestyle, sports-inspired eyewear, daily comfort-focused lines.
Acetate (Cellulose)	Plant-based material offering rich, multi-layered color patterns and hand-polished deep gloss (distinct from injection molding).	High-end boutique brands, optical-grade collections, premium private-label lines.

Customization Specifications

Frame Geometry & Surface Finishes
Available Silhouettes: Square, rectangular, round, oval, cat-eye, aviator, and wrap-around sports frames (subject to active mold inventories).

Surface Treatments: High-gloss tumble polish, rubberized matte coating, spray-painted gradient, or crystal-clear transparency matched to specified Pantone C codes.

Lens Configurations & Optical Standards
Material Options: Polycarbonate (PC) or Triacetate Cellulose (TAC).

Functional Performance:

UV Protection: Standard UV400 filtration (blocking 100% of UVA and UVB wavelengths up to 400nm).

Polarization: Reduces horizontal glare from reflective surfaces; verified via polarization test cards prior to assembly.

Optical Coatings: Revo mirror finishes, anti-reflective (AR) inner coatings, or custom gradient tints.

Branding & Private Label
Pad Printing / Silk Screen: Clean application on temple arms for standard brand marks and color graphics.

Laser Engraving: Permanent tonal contrast on matte or dark-finish frames.

Metal Badge / Inlaid Logo: Embedded metal plates or raised metal lettering mechanically riveted to temples for elevated retail positioning.

Quality Control & Testing Standards

Manufacturing operations follow a structured Quality Control (QC) framework to maintain batch consistency and minimize defect rates:

Incoming Material Inspection (IQC): Verification of raw polymer pellets, masterbatch color consistency, and lens optical purity.

In-Process Quality Control (IPQC): Dimensional checks using calibrated vernier calipers during injection molding, hinge alignment tests, and unit weight calibration.

Pre-Shipment Inspection (AQL 2.5/4.0): Finished goods are randomly inspected based on international sampling standards for cosmetic appearance, lens scratch resistance, logo adhesion, and drop-test packaging security.

Packaging & Logistical Specifications

Export packaging configurations protect products during global maritime and air transit:

Retail Presentation: Custom-printed folding paper boxes, collapsible or hard-shell EVA/PU leather cases, microfiber cleaning cloths (custom logo printed), and protective polybags.

Export Cartons: Standard multi-layer corrugated master cartons optimized for container-load calculations, providing clear gross weight (G.W.), net weight (N.W.), and CBM data for freight forwarders.

Frequently Asked Questions

Q: Can existing frame models be customized with proprietary branding?

A: Yes. Established catalog models support custom frame colors, lens tint/polarization configurations, laser/printed logos, and branded packaging, subject to model-specific minimum order quantities (MOQs).

Q: Do you accept custom OEM designs from technical drawings?

A: Yes. Custom tooling development is managed via CAD drawings, tech packs, or physical reference samples. Structural integrity, draft angles, and hinge placement are reviewed before mold cutting.

Q: What are the minimum order quantities (MOQs)?

A: MOQs vary depending on whether production utilizes an existing mold or requires new tooling, alongside material selection and branding complexity. Contact the engineering team with project specifics for tiered requirements.

Q: Are lenses certified for UV400 protection and global standards?

A: Yes. Lenses are manufactured to meet UV400 standards. Relevant test reports corresponding to specific lens batches and export destinations can be provided upon request.
