Round acetate and metal combination frames integrate the tactile depth and color versatility of cellulose acetate with the structural precision of exposed metal components. Engineered for optical wholesale, private-label brands, and prescription (Rx) retail collections, this category offers a balanced profile between vintage-inspired aesthetics and contemporary minimalist lines.

Custom Manufacturing & Development Workflow

Accommodates custom design specifications, private-label branding, and complete collection development based on technical requirements.

OEM Projects (Customer-Supplied Design): Submit 2D/3D CAD drawings, technical sketches, or physical reference samples. The engineering team reviews structural feasibility, mechanical tolerances, and tooling requirements before sample execution.

ODM Projects (Catalog & Customization): Select from existing round combination frame molds, specify custom acetate color sheets, metal plating finishes, laser logos, and bespoke packaging configurations.

Required Information for Project Review:

Reference model number, sketch, drawing, or sample

Exact material specifications (Acetate grade & metal type)

Color reference (Pantone codes or physical swatches)

Branding requirements (Logo vector files & placement)

Estimated order quantity (Minimum order quantities structured by model scope)

Destination market and specific compliance targets

Quality Control & Inspection Standards

To ensure structural integrity and functional reliability prior to bulk dispatch, frames undergo rigorous multi-stage quality inspections:

Dimensional Accuracy: Verification of lens width, bridge span, and frame symmetry against engineering drawings.

Mechanical Durability: Torque testing and cycle checks on hinge movement and temple alignment.

Surface Integrity: Inspection of acetate polishing, edge smoothness, and uniform metal plating without oxidation or pitting.

Assembly Tolerance: Ensuring secure lens-groove fit and flawless component alignment.

Packaging

Bulk optical frames require multi-layer packaging protection to prevent transit damage, frame distortion, and surface abrasion. Standard factory packaging is structured for international freight safety and retail distribution preparation.

Single Frame Protection: Each frame is individually enclosed in a clean polybag or protective sleeve to safeguard the acetate surface and metal plating from scratching during transit.

Inner Box Partitioning: Frames are arranged in secure, partitioned inner boxes or compartmentalized trays to restrict lateral movement and absorb mechanical shock.

Master Carton Integrity: Export shipments are packed in heavy-duty 5-layer corrugated master cartons, reinforced with edge protectors and moisture-barrier lining for ocean or air freight.

Frequently Asked Questions

Q: Are round acetate and metal frames compatible with progressive lenses?

A: Compatibility depends on the vertical lens height and frame depth. Frames with a vertical height under 35mm may limit progressive corridor space. Verify minimum fitting heights based on lens supplier requirements.

Q: What is the typical minimum order quantity for custom color combinations?

A: Minimum quantities vary depending on whether standard stock acetate sheets are used or custom-laminated color blocks must be manufactured. Contact the team with your specific color code to confirm minimum batch requirements.

Q: How do you ensure hinge and joint durability during bulk production?

A: Frames undergo pre-production prototyping and factory quality control checks covering hinge torque resistance, frame symmetry, and assembly integrity before final packaging.

Q: Can we get branded cases and cleaning cloths matching the frames?

A: Yes. Coordinated packaging accessories can be supplied, including branded hard cases, microfiber cleaning cloths, polybags, and custom outer boxes tailored to private-label programs.
