What are the structural differences between Pure Titanium and Beta Titanium frames?

Pure Titanium (99%+ Ti) offers unmatched corrosion resistance, superior biocompatibility, and rigid structural stability, making it optimal for CNC-milled eye wires and bridge assemblies. Beta Titanium (an alloy typically containing Vanadium and Chromium) delivers exceptional elasticity and tensile memory, making it ideal for screwless temples, flexible bridges, and high-deflection spring mechanisms.

How does Urband verify titanium purity and nickel-free compliance for EU/US customs?

Urband subjects every raw batch to X-ray fluorescence (XRF) spectrographic analysis to verify titanium grade and ensure nickel release complies with EN 16128 and REACH Regulation (EC) No 1907/2006. Full lot-specific laboratory testing files and CE declarations of conformity are provided prior to commercial export.

What surface finishing and coating methods are applied to prevent peeling on titanium?

Urband utilizes multi-arc Ion Plating (IP) Physical Vapor Deposition (PVD) inside vacuum chambers. This molecular deposition bonds directly to the passivated titanium surface, producing an ultra-hard (2000-2500 HV), scratch-resistant layer that withstands 72+ hours of artificial sweat and salt spray testing without flaking.

Can opticians easily adjust and glaze high-index lenses into ultra-thin titanium optical frames?

Yes. Urband designs its titanium eye wires with optical lab precision, incorporating optimal bevel angle profiles and engineered temple end-pieces that allow conventional optical pliers to adjust pantoscopic tilt, temple spread, and vertex distance without cold-work hardening or fracturing.

What is the typical Minimum Order Quantity (MOQ) and production lead time for wholesale titanium frames?

For our ready-to-ship original brand collections (EYELET, URBAND PARIS), MOQ is flexible starting from 50 to 100 units per style. For custom OEM/ODM titanium projects involving dedicated tooling, cold-forging dies, or bespoke IP electroplating colors, MOQs typically range from 300 to 500 units per colorway with a 60 to 75-day precision production cycle.

Strategic Market Forecast

Future B2B Procurement Trends in Titanium Optical Frames (2025–2030)

Global optical retail data shows accelerated migration away from commodity plastics toward durable, repair-friendly titanium optical frames. Procurement teams must adapt to three structural supply-chain shifts:

Zero-Screw Modular Architecture: Dispensing opticians increasingly demand screwless hinge mechanics. Eliminating micro-screws completely removes the #1 cause of optical return repairs (stripped threads, loose hinge barrels, and lost components).
Eco-Certified Physical Vapor Deposition (PVD): Traditional chemical electroplating faces severe regulatory crackdowns in the EU (REACH) and US (EPA). Multi-arc vacuum ion-plating is now mandatory for high-tier buyers, offering 2000-hour artificial sweat resistance with zero toxic chemical runoff.
Hybridization with Bio-Acetate & Polyamides: Monolithic metal is giving way to dual-material frames where featherweight titanium skeletons provide structural alignment while bio-based acetate rims create bold visual retail appeal without front-heavy slippage.

Industry R&D Horizons

Manufacturing Evolution: How Titanium Frames Are Engineered Today

The manufacturing of titanium eyewear has transitioned from labor-intensive manual brazing to cleanroom CNC laser ablation and micro-die hydraulic cold forging.

5-Axis CNC titanium precision micro-machining

5-Axis CNC Micro-Milling

Titanium reacts rapidly with atmospheric oxygen at elevated temperatures. Urband utilizes pressurized argon inert-gas shielded CNC milling centers that machine solid titanium blocks into integrated front pieces without thermal stress or micro-fissuring.

Screwless tension hinge assembly mechanism

Integrated Friction-Lock Hinges

Our proprietary screwless hinge geometry is laser-cut from high-elasticity beta titanium sheets. By relying on mechanical tension interlocks rather than threaded screws, our hinges maintain silky smooth folding friction through tens of thousands of cycles.

Titanium surface treatment and vacuum ion plating

Sub-Micron Plasma Ion Plating

Physical Vapor Deposition (PVD) vaporizes ceramic-metallic compounds (such as Titanium Nitride and Carbon-Nitride) in high-vacuum chambers. The resulting ionic bond yields scratch resistance rated at 2200 Vickers while delivering luxury matte and mirror finishes.

Procurement Knowledge Base

Frequently Asked Questions by Global Eyewear Buyers

Clear, technical answers to the most common metallurgical, commercial, and regulatory questions submitted to our B2B procurement division.

Pure Titanium (Grade 1 and Grade 2, containing over 99% pure titanium) features high tensile stiffness, superior chemical inertness, and exceptional biocompatibility. It is best used for rigid front eye wires, bridges, and endpieces that require permanent optical alignment without drifting. Beta Titanium (an alloy combining titanium with vanadium, chromium, and aluminum) exhibits a lower modulus of elasticity with extreme flex memory. It can bend beyond 90 degrees and spring back immediately to its original geometry, making it the premier material for flexible temples, pressure-free temples, and screwless hinge linkages.

Every production batch of raw titanium wire and sheet metal is validated using X-ray fluorescence (XRF) spectrographic analysis. In addition, finished frames undergo simulated wear and electrolytic testing according to EN 16128:2015 to verify that nickel release does not exceed the mandatory threshold of 0.5 μg/cm²/week under REACH Annex XVII entry 27. Every international wholesale consignment is shipped with factory lot-matched laboratory certificates, CE Declarations of Conformity, and ISO 12870 technical dossiers ready for immediate customs clearance.

Because titanium naturally forms an inert titanium dioxide passivated film, conventional wet electroplating easily chips and flakes over time. Urband solves this by using high-vacuum Physical Vapor Deposition (PVD) Ion Plating (IP). Inside an ultra-clean vacuum chamber, ionized coating particles are accelerated by an electrical field into the titanium substrate, creating a molecular-level bond. This produces a micro-hardness coating of 2000 to 2500 Vickers that withstands 72+ hours of continuous artificial sweat testing without peeling, color fading, or oxidation.

Yes. Urband's engineering team draws upon founder Yang Wah Kiang's hands-on lens grinding heritage to ensure all titanium rims feature standardized 110-degree V-groove geometries with a minimum depth of 0.6 mm. This prevents high-index lenses from chipping at the bevel edge during automated edging. Furthermore, our pure titanium bridges and temple end-pieces are annealed to allow opticians to modify face-form angle, pantoscopic tilt, and temple spread using standard optical nylon-jaw pliers without risk of metal crystallization or weld-joint snapping.

For wholesale distributors sourcing from our in-stock original brand portfolio (EYELET, URBAND PARIS, GLOSSI), MOQs are highly accessible, starting from 50 to 100 units across mixed colorways, ready to ship within 7 business days from our Shenzhen/Singapore hubs. For customized OEM/ODM production requiring unique tooling, custom color IP deposition, or private labeling, standard MOQs are 300 to 500 units per style (minimum 100 units per color), with a precision production cycle of 60 to 75 days.
