Acetate Round Optical Frames

Cellulose acetate round optical frames pair classical circular geometry with industrial-grade structural stability. Produced from renewable plant-based wood and cotton pulp derivatives, these frames provide high color saturation, hypoallergenic surface properties, and thermal adaptability for prescription adjustments. Designed for optical brand owners and wholesale distributors, the frames accommodate single-vision, progressive, and blue-light lenses. Manufacturing relies on multi-axis CNC routing for exact eyewire perimeters and manual tumbling processes for smooth touch points.

Hypoallergenic Organic Substrate: Renewable cellulose structure minimizes skin reactivity compared to petroleum-based injection plastics.

Embedded Core Wire: 0.8 mm surgical stainless steel wire encased within the temples allows opticians to adjust grip force and pantoscopic angles securely.

Multi-Stage Polishing: Combined barrel tumbling and manual wheel finishing eliminate micro-scratches to yield a deep, uniform luster.

Dimensional Stability: High-density acetate sheets resist sweat-induced degradation and prevent frame twisting during daily wear.

Calibrated Lens Grooves: V-groove channels milled to a precise depth of 0.8 mm secure prescription lenses and prevent edge rotation under pressure.

Structural performance depends on multi-layer sheet lamination and precision hardware anchoring. Front bezels are cut from multi-layered acetate blocks using 5-axis CNC machinery to maintain bridge symmetry and rim width tolerances.

Hinges utilize thermal insertion techniques, anchoring metal fastening prongs directly into the core acetate material to endure a minimum of 10,000 open-close operational cycles. The bridge is engineered with an integrated saddle design or standardized pad-mounting areas to distribute weight evenly across the wearer's nasal bridge.

Color Selection: Solid tones, classic Havana patterns, crystal clear, gradient fades, multi-layer laminates, and custom Pantone color matching.

Surface Finishes: High-gloss polish, matte tumbled texture, or brushed vintage finishes.

Custom Branding: Laser engraving of brand logos, model codes, and size specs on inner temple arms.

Dimensional Customization: Lens widths ranging from 44 mm to 54 mm; bridge spacing from 18 mm to 24 mm; temple lengths from 135 mm to 155 mm.

CAD/CAM Engineering: Technical teams convert 2D drawings or 3D STEP files into production toolpaths within 48 hours.

Prototyping Protocols: 3D-printed resin samples or hand-milled physical acetate prototypes delivered in 7 to 10 days for ergonomic evaluation.

Private Label Integration: Custom hot-foil stamping, interior temple laser etching, and serialized batch coding.

Packaging Coordination: Hard-shell cases, microfiber cloths, branded cleaning sleeves, and master cartons featuring custom barcode labels.

Operations span a 15,000-square-meter facility housing 30 CNC milling workstations, automated drum-polishing units, and optical inspection benches.

Quality assurance follows a strict 4-stage protocol:

Raw Material Audit: Verification of cellulose acetate sheet moisture levels and thickness variations (maintained within < 0.05 mm limits).

In-Process Inspection: Dimensional checks of eyewire perimeters and hinge alignment using optical projectors during CNC milling.

Mechanical Testing: Drop-ball lens impact tests, spring hinge fatigue resistance checks, and chemical sweat-immersion evaluations.

Final Inspection: 100% manual review for surface defects, groove depth consistency, and temple symmetry before bulk boxing.

Prescription Ophthalmic Frames: Standard frames for single-vision, bifocal, and progressive prescription lenses.

Sunwear & Sunglasses: Frame platforms compatible with polarized CR-39, nylon, and glass sun lenses.

Screen Protection Eyewear: Blue-light filtering glasses configured for corporate and retail channels.

Boutique Fashion Collections: Private-label capsule lines engineered for independent eyewear brands.

Unit Packaging: Individual polybag with silica gel desiccant; optional hard leather case and microfiber pouch.

Master Carton Configuration: 12 pieces per inner box, 20 inner boxes per master carton (240 pieces/carton). Carton size: 60 x 40 x 50 cm. Gross weight: ~14 kg.

Minimum Order Quantity (MOQ): 300 pieces per model (allocated across up to 3 colorways; 100 pieces per color).

Production Lead Time: 35 to 45 days following technical sample approval and deposit confirmation.

Shipping Terms: FOB, CIF, EXW, or DDP via air freight or ocean container.
