Each material demands distinct mechanical protocols. We maintain specialized workshops to process cellulose acetate, pure titanium, memory alloys, and engineered thermoplastic polymers.
Cellulose acetate frames undergo computer-controlled CNC routing from cured sheet slabs. Multi-axis cutting tools precisely profile the lens bevel channel, bridge curvature, and temple core-pin insertion slots to tolerances within ±0.05mm. This guarantees optical symmetry and prevents cold-snap lens dislodgement.
Milled blanks undergo progressive dry and wet tumbling cycles across 72 continuous hours using organic pumice and birch wood cubes, yielding an optical surface free of tool marks prior to final hand-buffing.
Utilizing high-grade steel tooling and Swiss-made Grilamid TR90 pellets, micro-injection molding produces ultra-flexible, featherweight frames. Automated cooling and mold-flow simulations prevent internal residual stress and optical groove warpage.
Cold-swaged pure titanium rims and beta-titanium flexible temples are formed under robotic tooling. Laser micro-welding in an inert argon gas chamber creates high-strength joints that eliminate solder oxidation and maintain hypoallergenic purity.
Integration of screwless locking joints and spring-activated mechanisms. Each hinge batch undergoes automated 20,000-cycle opening and closing stress tests to certify tension retention, smooth angular travel, and play-free temple alignment.
Quality assurance is not treated as a final checkpoint, but as a continuous gate-keeping system from raw material verification to container loading.
| Inspection Gate | Verification Items & Metrology Standards | Quality Record Produced |
|---|---|---|
| 1. Raw Material Gate (IQC) | Spectrophotometer color check, acetate moisture content analysis, raw titanium tensile strength check, and chemical screening against banned substances. | Raw Material Release Certificate (CoC) |
| 2. In-Process Milling & Forming (IPQC) | Optical comparator dimensional analysis (±0.05mm), bridge angle symmetry, lens groove depth and bevel geometry, and weld joint penetration. | Hourly In-Process Inspection Log |
| 3. Surface & Coating Gate | Cross-hatch adhesion testing, sweat resistance immersion test, artificial perspiration test (ISO 12870), and nickel release analysis (EN 16128). | Surface Integrity Report |
| 4. Mechanical & Assembly Gate | 20,000-cycle hinge endurance, temple flexural fatigue resistance, optical bridge deformation under load, and screw torque retention. | Mechanical Compliance Record |
| 5. Final Outgoing Gate (OQC) | Planar tabletop 4-point balance, cosmetic finish under 1,000 Lux illumination, laser marking clarity, barcode scannability, and carton packaging. | Pre-Shipment Inspection (PSI) Certificate |
Every production lot is assigned a traceable internal batch code laser-etched onto inner temple surfaces or logged on accompanying lot packaging. This ensures complete transparency across raw material supplier lots, tooling shifts, plating tanks, and operator stations.
Our internal testing lab conducts rigorous environmental aging simulations, including 48-hour thermal cycle tests (-10°C to +55°C), high-humidity chamber exposure, and ultraviolet yellowing resistance tests to ensure frames endure real-world retail lifecycles.
Global optical importers and retail chains rely on our product-specific compliance records to clear customs seamlessly in North America, Europe, Australia, and Asia.

Urband coordinates full-cycle manufacturing: CNC acetate milling, precision injection molding, metal and pure titanium forming, vacuum ion plating, automated surface tumbling, pad printing, laser engraving, engineered hinge integration, lens edging, and retail packaging according to the confirmed frame construction.
Confirmed eyewear production capacity is 600,000 pcs per month. The final production schedule is determined based on materials, colors, mold readiness, specialist finishes, hardware, packaging, quantity, and sample approval.
Available resources for frame manufacturing support CNC-cut sheet frames, injection-molded frames, metal and titanium frame structures, mixed-material assemblies, hardware-intensive designs, and frames requiring lens edging.
Yes. Standard hinges, spring hinges, screw-less structures, active hinge configurations, screws, nose pads, temple tips, decorative hardware, and silicone parts can be integrated as long as the component specifications and frame construction have been confirmed.
Yes. Urband has more than 20 Essilor edging machines to support lens-shape cutting, bevel control, frame matching, mounting, and basic verification of lens shapes and mounting based on the confirmed frame specifications.
The inputs that support sample production include the frame drawing or reference sample, target material, dimensions, colors, logo artwork, quantity, packaging files, target market, and any required inspection criteria.
The standard production lead time is 10 days from confirmation of the required files, artwork, sample, materials, and order details. New molds, constrained materials, specialist finishes, or custom packaging may affect the confirmed production schedule.
Depending on the order, available production records may include approved-sample identification, color references, in-process inspection findings, final inspection results, packaging revisions, quantities, and batch identification.
