Core Engineering & Material Considerations

Material Integrity and Alloy Grade
Titanium is specified in eyewear manufacturing for its high strength-to-weight ratio, low density, and corrosion resistance.

Material Transparency: Each model specifies whether pure titanium or titanium alloys are utilized for structural components such as eyewire rims, bridges, and temples.

Component-Level Breakdown: Hinges, screws, and pad arms are engineered with matching corrosion-resistant materials to ensure structural longevity under daily wear.

Precision Dimensional Control
Round frames demand exact geometric symmetry to ensure correct optical alignment and lens edging. Manufacturing tolerances are monitored across critical dimensions:

Lens Diameter & Height: Ensures precise fit for standard and progressive prescription lenses.

Bridge & Temple Proportions: Designed for ergonomic weight distribution and stable facial fitting across varying head shapes.

Hinge Alignment: Multi-barrel or spring hinges are aligned within strict parallelism tolerances to prevent binding or loose temple action.

Surface Finishing & Electroplating
Surface treatments protect the titanium substrate and define the aesthetic presentation of the frame.

Finishing Methods: Available in vacuum ion plating (IP plating) and anodized finishes.

Durability Testing: Finishes undergo standard adhesion and sweat-resistance evaluations to prevent premature peeling or discoloration.

OEM & ODM Customization Scope

Comprehensive custom eyewear development is supported based on technical specifications, 3D drawings, or physical reference samples.

Branding: Laser engraving, acid etching, or pad printing of brand logos on temples, bridge interiors, or end-tips.

Colorways: Custom IP plating finishes (e.g., Matte Black, Brushed Gunmetal, Rose Gold, Titanium Silver, Antique Bronze).

Component Customization: Selection of hinge types, temple tip materials, and nose-pad configurations.

Packaging Solutions: Custom-branded hard cases, microfiber cleaning cloths, drawstring pouches, and outer retail packaging.

Quality Assurance & Testing Protocols

To minimize supply chain risk, production batches undergo structured quality control checks at key manufacturing milestones:

Raw Material Verification: Material composition and grade verification against technical documentation.

Dimensional Inspection: Caliper and optical comparator checks on lens width, bridge span, temple length, and frame diagonal symmetry.

Mechanical Testing: Hinge cycle endurance testing, screw retention security, and joint weld strength checks.

Surface & Cosmetic Inspection: 100% visual inspection under standardized lighting for plating uniformity, tool marks, and sharp edges.

Pre-Shipment Inspection (PSI): Final verification of master carton quantities, color assortment ratios, labeling accuracy, and protective packaging against approved purchase orders.

Compliance & Regulatory Standards

Export production adheres to international environmental safety and material compliance requirements for global optical markets:

Chemical & Material Safety: Nickel release testing and plating compliance aligned with regional standards (such as REACH or equivalent market regulations).

Traceability: Full batch tracking from raw material intake to final assembly.

Documentation: Material test reports and inspection certificates available upon request prior to order placement.

FAQ

Q: Are these frames manufactured from pure titanium or titanium alloy?

A: The exact material composition varies by model reference. Specific material grades (such as Titanium Grade 1/2 or Beta-Titanium components) are detailed in the technical datasheet supplied upon inquiry.

Q: What is the minimum order quantity (MOQ) for custom titanium frames?

A: MOQs depend on whether you select existing catalog models with custom logo branding or initiate a full OEM/ODM development. Contact our team with your target volume to receive specific tiered pricing.

Q: Can we request custom frame sizes or modifications to an existing model?

A: Yes. Dimensional adjustments, alternative bridge designs, or custom plating colors can be evaluated during the engineering review stage based on tooling feasibility.

Q: Are prescription lenses included with the optical frames?

A: Frames are standardly supplied with clear demo lenses for display and fitting purposes. Prescription lens installation can be coordinated if required by your program specifications.

Q: What information is required to receive an accurate quotation?

A: Please provide your model reference number or design sketches, estimated order volume, required color finishes, logo placement artwork, packaging specifications, and target destination port.
