About Elistro Dealer Program ContactExplore our top-selling export collection of handcrafted cellulose acetate fronts, aviation double-bridge profiles, hybrid titanium combinations, and protective optical accessories developed for high sell-through performance.
As optical retail transitions from disposable fast-fashion models toward sustainable luxury, private-label optical chains and independent distributors require higher technical accountability, verifiable raw material provenance, and multi-material engineering sophistication.
Traditional cellulose acetate uses phthalate-based plasticizers (such as DEP). Global procurement standards now mandate bio-based, biodegradable formulations derived from sustainably harvested cotton linters and wood pulp with bio-plasticizers compliant with ISO 14855 standards.
Optical buyers are demanding dramatic weight reduction without sacrificing the rich volumetric aesthetics of handmade acetate. Advanced frames integrate ultra-thin 4.0mm acetate rim fronts with cold-forged Japanese beta-titanium core wires and spring-loaded German barrel hinges.
B2B brand directors no longer source frames, cases, microfiber cloths, and outer presentation boxes from separate suppliers. Purchasing managers demand consolidated turnkey delivery where the eyewear, embossed folding case, branded cloth, and barcoded cartons arrive co-inspected.

Modern cellulose acetate frame production is a symbiotic marriage between 5-axis robotic milling and centuries-old artisan finishing. Here is how our production facility ensures micron-level precision from raw slab to optical dispensing.
Cellulose acetate sheets undergo a 60-day climate-controlled curing process to eliminate internal solvent tension. This critical thermal aging prevents post-manufacturing warping, shrinkage, and lens pop-out when exposed to real-world optical shop glazing environments.
Utilizing diamond-tipped rotary cutters, raw cured slabs are milled into multi-dimensional front profiles within ±0.05mm tolerances. Lens eyewire grooves, pad arms, and inner bevels are carved with zero frictional heat build-up to maintain structural crystalline integrity.
Rough cut fronts undergo 72 consecutive hours of centrifugal barrel tumbling through crushed birchwood chips, walnut shells, and graded pumice creams. This organic abrasive cycle smooths edge sharpness into tactile, ergonomic curves that sit naturally on facial contours.
Final high-gloss finishes are created by master polishers on spinning cotton buffing wheels with bespoke jeweler's rouge. Hinges are double-pinned, temple tension is torque-calibrated, and four-point planar bench alignment is verified prior to clean-room packaging.
Our factory combines industrialized volume manufacturing with bespoke atelier craftsmanship. Every SKU in our inventory reflects strict compliance with CE, ISO 12870, and FDA Class I medical device regulations.
We do not produce generic one-size novelties. Every silhouette is calibrated with precise international optical geometry (Lens Width □ Bridge Width – Temple Length, e.g., 53□19-145mm) designed to accommodate high-diopter prescription lenses, progressive bifocals, and diverse regional pantoscopic tilt requirements.
Elevate your customer's unboxing experience. Every frame program can be bundled with our matching accessory suites: PU leather travel carriers, luxury rigid cardboard clamshells, microfiber anti-static lint-free cloths, warranty credential cards, and retail shopping bags with your custom hot-stamped branding.
We specialize in supporting regional eyewear wholesalers, optometric chains, and private labels. Enjoy low minimum order quantities (MOQs) on in-stock export designs, rapid sample prototyping, CAD rendering revisions within 48 hours, and dedicated customs clearance documentation support.
Technical, logistical, and commercial inquiries routinely handled by our senior engineering and export sales divisions.
Extruded acetate is melted and pushed through dies, resulting in lower structural density and limited pattern depth. Block cast cellulose acetate (which we specialize in) is laminated under hydraulic pressure and cured over months. This creates unmatched color depth in tortoiseshell and marble hues, prevents temple warping over time, and allows precise heat adjustments by opticians.
Yes. We offer fully custom laser-etched and stamped German-silver core wires visible through crystal-clear and translucent acetate temples. Furthermore, we provide 3-barrel, 5-barrel, and 7-barrel custom hinges, OBE safety screws, and teflon-coated friction rings that resist loosening over thousands of open-close flex cycles.
For custom manufactured acetates featuring bespoke colorway slabs and private logo tooling, our standard MOQ is typically 300 pieces per model (divided into 2 to 3 colorways, 100 pcs per color). For items selected from our existing ready-to-ship export catalog, low test-order quantities start at 50 to 100 units per model.
Every frame batch complies with AQL 1.5 standards. Inspections include: bridge endurance fatigue testing (20,000 continuous hinge cycles), sweat resistance immersion tests (pH 4.5 acidic bath for 24 hours), nickel-release compliance testing (EN ISO 12870), lens eyewire groove sizing verification, and hand 4-point planar leveling on marble reference slabs.
By consolidating optical frames with custom-tailored rigid storage boxes, PU hanging cases, and microfiber cleaning cloths at factory origin, buyers eliminate secondary domestic assembly labor, reduce dimensional shipping volume, and ensure exact color and dimension synchronization between the frame and its packaging.
The standard boxing system indicates the horizontal lens width (50mm), distance between lenses or bridge width (21mm), and overall temple length (145mm). These precise metrics allow your laboratory edging technicians to accurately calculate effective diameter (ED), decentration, and minimum blank size before cutting single-vision or progressive lenses.
Whether you are sourcing custom cellulose acetate eyewear, beta-titanium hybrids, or turnkey retail accessory collections, our global engineering team provides rapid prototyping, transparent wholesale pricing, and guaranteed delivery schedules.
