Engineered for optical retail chains, independent ophthalmology practices, and global distributors. Examine our turnkey acetate, surgical stainless steel, beta-titanium, and lightweight memory polymer solutions ready for immediate OEM/ODM batch customization.
Unlike trading brokers, Urband combines European frame ergonomics, Japanese micro-mechanical R&D heritage, and automated Shenzhen manufacturing to eliminate supplier fragmentation for optical chains.
Founded on the bench-grinding discipline of Yang Wah Kiang, who co-established Nanyang Optical in Singapore. Decades of optical dispensing know-how directly inform our bridge pantoscopic angles, face-form curvatures, and groove depths for stress-free lens glazing.
Honored with 14 prestigious awards, 6 nominations, and 1 invited accolade across the iF Design Award, Red Dot Design Award, SILMO d'Or, and Singapore President's Design Award. Our frames offer undeniable aesthetic authority at the optical counter.
Pioneers of frictionless kinematics: our proprietary Screwless Hinge eliminates lost hinge screws, while the Active Hinge dampens lateral stresses via elastic memory components, maintaining consistent opening torque over 25,000 continuous cycles.
For procurement executives evaluating dimensional stability, color fastness, hypoallergenic properties, and post-dispensing cold-bend memory in high-volume retail environments.

How Urband’s Shenzhen production facility coordinates micron-level tolerances from aged block slabs to ultrasonic hinge insertion.
Extruded acetate sheets are oven-cured at 60°C for up to 90 days to eliminate residual volatile solvents, preventing frame warping after retail distribution.
High-speed precision spindles carve front eyewires, bridge profiles, and internal lens bevels down to a ±0.05mm margin for perfect lens optical alignment.
High-frequency induction heating shoots German nickel-silver structural core wires into temple cores, providing exact anatomical adjustability for opticians.
4 successive cascading cycles utilizing Italian beechwood chips, granulated walnut shells, and pumice paste to achieve smooth, mirror-finish crystal luster.
Multi-barrel custom hinges are welded directly into the heated acetate matrix, ensuring 180N temple pull-out resistance exceeding ISO durability standards.
Global optical chains and frame importers face shifting trade regulations, carbon disclosure mandates, and evolving consumer ergonomics. Here are the 4 fundamental purchasing shifts transforming the supply chain.
European retailers are systematically converting frame inventories to certified Bio-Acetate (M49 standard). Formulated without phthalates using bio-derived triethyl citrate (TEC) plasticizers, these compounds degrade cleanly while preserving CNC polish depth.
The fastest-growing retail SKU category combines ultra-thin 4.0mm acetate windsor rims mounted within beta-titanium chassis. Sourcing departments capture high retail margins by combining the featherweight rigidity of titanium with acetate's color rich profiles.
Forward-thinking exporters are designing acetate temples with standardized internal micro-cavities to host micro-sensors, open-ear audio transducers, and bone-conduction coils without disrupting traditional hot-water optical dispensing adjustments.
Importers face stringent EU MDR (Medical Device Regulation) and US FDA Class I specs. Contract factories must deliver batch-level chemical migration documentation, nickel-release certifications (EN 16128), and audited traceability for every resin batch.
Ensure your landed shipments withstand clinical lens glazing, extreme shipping thermals, and post-purchase consumer wear. Our 5-tier laboratory testing pipeline guarantees unyielding field reliability.
Subject to EN ISO 12870 clauses, the nasal bridge is loaded with cyclic mechanical force (up to 50N). Frame front bridge recovery must exhibit < 1.5% plastic deformation to prevent optical axis displacement during wearer usage.
Samples undergo 24 hours at 60°C ± 2°C followed by -10°C cycles. This stresses the bond between embedded metal core wires and acetate polymers, screening out delamination, cloudiness, and surface blistering.
Submerged for 24 hours in an artificial perspiration bath at 37°C (pH 5.5). Hinges, rim screws, and core wires are inspected under 20x magnification for signs of galvanic pitting, discoloration, or joint seizing.
Direct answers to commercial, technical, and logistical inquiries commonly encountered by optical category directors, chain store buyers, and OEM brand founders.
For fully bespoke OEM/ODM frame development involving custom color sheet extrusion, MOQ typically starts at 300 to 500 pairs per model, divided into 2 to 3 color variants (100–150 pairs per color). For our open-catalog models or in-stock acetate acetate series, ready-to-ship branding orders start as low as 50 to 100 pairs.
We execute binding bilateral Non-Disclosure Agreements (NDAs) prior to receiving 2D technical drawings or 3D STEP/IGES files. Proprietary tooling, specialized core wire embossing dies, and custom sheet laminate formulas remain the exclusive property of the commissioning client and are never repurposed for general catalog lines.
Our Screwless Hinge relies on an engineered interlocking cam and slotted barrel interface that eliminates mechanical screws entirely, permanently preventing loose temples and screw-drop field complaints. The Active Hinge incorporates internal resilient spring mechanics to absorb lateral shocks and automatically return the temple to standard pantoscopic tension, ideal for active and youth eyewear.
Every delivery is certified to ISO 12870:2016 (Ophthalmic Optics - Spectacle Frames) and includes formal Declarations of Conformity for CE Marking under EU Medical Device Regulation (EU) 2017/745. Furthermore, our products comply with US FDA Device Listing regulations and undergo independent laboratory screening for SVHC substances under REACH (EC No 1907/2006).
CNC physical prototyping and SLA 3D print verification samples require 14 to 21 working days. Following physical sample approval and master resin confirmation, volume production runs require approximately 60 to 75 days, accounting for multi-stage aging ovens, 5-axis milling, tumbling, hand buffing, and laboratory QC batch testing.
Yes. A single wholesale corporate account allows global importers to cross-order and consolidate collections from EYELET (children's flexible Rx), GLOSSI (vibrant women's fashion acetate), URBAND PARIS (architectural sports-Rx frames), and COUPLE (reading presbyopia), dramatically cutting freight costs, customs clearance handling, and administration overhead.
