About Elistro Dealer Program ContactConstructed with high-ductility aerospace-grade Beta-Titanium alloys (Ti-15V-3Cr-3Sn-3Al), each silhouette delivers sub-8.5g structural equilibrium, zero galvanic corrosion, and bio-compatible ion-plated finishes calibrated for high-end boutique optical retail.
For Swiss Master Opticians (Augenoptiker-Meister) and chain procurement teams, material purity determines not only temple memory retention but also glazing reliability during lens bevel fitting and digital progressive edging.
Beta titanium is metastabilized through high-solute alloying elements (15% Vanadium, 3% Chromium, 3% Aluminum, 3% Tin). This creates a body-centered cubic (BCC) crystal lattice that provides twice the spring elasticity of pure Alpha Titanium (CP-Ti) and double the fatigue resistance of stainless steel or Monel, completely resisting temple outward splay over years of use.
Our precision facility applies cathodic arc Physical Vapor Deposition (IP) within a high-vacuum chamber (<10⁻⁴ Pa). With Titanium Carbonitride (TiCN) and Zirconium Oxide foundations, our finishes deliver 2200 Vickers surface hardness, enduring Swiss Alpine perspiration, thermal cycling (-25°C to +35°C), and synthetic skin-acid contact with zero flaking.
Skin allergies represent a critical consumer concern in German-, French-, and Italian-speaking Switzerland. Our Beta-Titanium optical frames strictly eliminate nickel leaching, conforming cleanly to standard EN 16128:2015 (< 0.05 μg/cm²/week limit). Frames are thoroughly bio-inert, non-cytotoxic, and resistant to galvanic reaction with sweat salts.
Benchmarking mechanical tolerances against standards prevalent across Swiss optical chains like Visilab, McOptic, Fielmann CH, and independent guild opticians.

From Zurich’s Paradeplatz executive desks to the high altitudes of St. Moritz and Zermatt, beta-titanium frames meet strict consumer expectations for understated luxury, functional precision, and enduring durability.
Corporate professionals, private bankers, and legal counsels demand ultra-minimalist, rimless and semi-rimless frames. Thin beta-titanium wires ensure pressure-free contact at the mastoid bone and temporal lobe throughout 14-hour visual workdays.
Biotech researchers and medical engineers require frames unaffected by continuous sanitization, alcohol wiping, and clinical cleanroom temperature changes. Non-magnetic beta-phase titanium avoids interference with sensitive NMR and MRI lab gear.
Across Engadin, Valais, and Bernese Oberland, users shift swiftly from freezing outdoor slopes (-15°C) to heated interiors (+22°C). Unlike conventional plastics that become brittle, Beta-Ti maintains molecular elasticity, preventing thermal stress fractures.
Boutique opticians in Bern, Lucerne, and Lausanne look for small-batch customizables with private label engraving. Our beta-titanium chassis supports high minus prescriptions (up to -10.00D) with deep-groove lens retention and uniform stress dispersion.
Key shifts impacting Swiss optical purchasing decisions, sustainable metallurgy, medical device regulations, and direct B2B supply lines.
As Switzerland aligns its Medical Devices Ordinance (MedDO/MepV) with EU MDR 2017/745, prescription ophthalmic frames demand documented material traceability, bio-compatibility certifications, and audited factory batch numbers. Our factory provides comprehensive Technical Construction Files (TCF) with every wholesale shipment.
Traditional five-barrel and spring hinges degrade in dry indoor heating during Swiss winters. Modern buyers favor screwless interlocking hinges cut directly from the beta-titanium temple blank. With no micro-screws to work loose, opticians drastically reduce post-sale adjustments.
Rising retail overheads across high-rent locations (Zurich Bahnhofstrasse, Geneva Rue du Rhône) are encouraging Swiss opticians to bypass legacy intermediaries. Sourcing direct from certified manufacturing plants helps retailers protect gross margins of 65% to 80% without lowering quality.
Integrating Japanese cold-forging metallurgy, 5-axis German CNC milling, and comprehensive Swiss packaging suites into a streamlined manufacturing pipeline.
Equipped with 42 high-precision CNC tool stations capable of cutting 0.6mm ultra-thin β-Ti sheets and profile-drawn wires within ±0.03mm tolerances. Bridges and rim lock barrel joints are milled directly from billet blanks, preserving structural integrity.
Following Japanese hand-barrel deburring with walnut shell granules, every single titanium frame is hand-buffed by senior artisans. Temple ends, nose bridge contact points, and solder joints receive a final 100% optical microscope review before packing.
Each frame ships ready for immediate boutique counter display, accompanied by a rigid boutique case, microfibre cleaning cloth, branded luxury gift box, customized shopping bag, and an authenticity/warranty card for an elevated consumer handoff.
We provide precision fiber-laser temple marking (SKU, cantonal registration markers, CE markings, custom house brand typography) at 40-micron resolution. Our streamlined export team manages direct air dispatch directly to Zurich (ZRH) and Geneva (GVA), clearing Federal Customs Administration (FCA) formalities efficiently.
Answers to common operational, regulatory, import, and technical glazing questions asked by Swiss ophthalmic professionals.
Under Swiss customs tariff provisions (Tares code 9003.1100 / 9003.1900), spectacle frames imported from certified manufacturing facilities enjoy zero or favorable duty structures with correct origin documentation. We handle DAP (Delivered at Place) and DDP air cargo consignments, providing complete EUR.1/origin certificates and automated documentation for clean Swiss Federal VAT (8.1% MWST) clearance.
Yes. Every production batch is certified under DIN EN ISO 12870 (Ophthalmic Optics - Spectacle Frames). This includes standardized testing for sweat resistance, optical frame dimensional stability, mechanical endurance (500 cycles of temple flexure without plastic deformation), and non-flammability. Technical files are provided to support Swiss MedDO/MepV audits.
Yes. Our full-rim frames feature a specialized 1.4mm deep V-groove designed to secure thick high-minus myopic lenses (up to -9.00D or high refractive index 1.74 plastic lenses) without outward bezel bulging. For rimless designs, our high-density dual-compression bushings eliminate local strain concentration on delicate high-cylinder progressive lenses.
To support independent optical shops and regional chains, our ready-to-ship stock program maintains an ultra-accessible entry point of just 50 units across mixed silhouettes. For private label OEM collections featuring custom IP colors, bespoke temple tip laser engraving, and custom packaging, minimums begin at 300 units per model.
Standard wet electroplating typically utilizes an intermediate nickel strike layer to bond gold or black finishes. Our factory uses 100% dry, eco-friendly PVD Ion Plating in high-vacuum chambers. This delivers molecular adhesion directly to the passive titanium oxide surface, generating twice the scratch resistance without using cyanide baths or toxic nickel compounds.
Beta-titanium possesses a broad elastic deflection zone. While highly spring-elastic, opticians can create precise, permanent ergonomic ear-curve adjustments using standard hollow-chop or flat-faced optical pliers, provided pressure is applied at the designated cold-working zone along the temple core.
