About Elistro Dealer Program ContactEngineered for independent optical practices, distribution networks, and optical chains seeking maximum shelf turnover and reliable dimensional stability.
Combining sustainable bio-cellulose curation, artisan tumbling processes, and rigorous dimensional standards to secure our clients' competitive edge.
We source ultra-dense, cured cellulose acetate sheets derived from renewable wood pulp and cotton fibers. Controlled chamber-aging eliminates internal solvent residue, preventing temple warping, bridge flattening, or shrinkage during optometric heat adjustments.
Our multi-axis automated CNC cutting stations carve complex frame grooves and lens bevels down to a strict ±0.05mm tolerance, delivering seamless cold lens insertions and exact base-curve fidelity for RX lab glazing across varying lens powers.
Raw acetate blanks undergo a proprietary 72-hour wet-and-dry tumbling protocol using natural birch pegs, pumice stone, and specialized walnut shell pastes, followed by master artisan hand-buffing to produce an enduring, hypoallergenic luster.
A systematic evaluation of mechanical properties for procurement directors comparing acetate, titanium, and TR90 for private label production.
| Evaluation Parameter | Cellulose Acetate (Bio-Grade) | Beta-Titanium Alloy | Injected TR90 Polymer |
|---|---|---|---|
| Optometric Adjustability | Exceptional (Heat pliable at 55°C–65°C without degradation) | Cold pliable on temple arms; rigid bridge alignment | Low memory elasticity; cannot retain custom cold bend |
| Color Stratification & Depth | Deep 3D tortoiseshells, horn effects & multi-layer lamination | Anodized solid tones, vacuum ion plating | Surface coating or bulk monolithic dyed pigmentation |
| Weight & Sensory Feel | Substantial, premium tactile density with natural skin warmth | Ultralight featherweight; minimal presence | Extremely lightweight; synthetic hand-feel |
| Skin Compatibility | Hypoallergenic, natural plant-based formulation | 100% Biocompatible, completely nickel-free | Hypoallergenic medical-grade resin |
| Target Retail Positioning | Luxury, designer optical boutiques, premium chains | Executive minimalist, ultra-high-end optometry | Performance sports, casual reading, fast-fashion tiers |
From unrefined organic raw sheets to final optical dispensary readiness.
Cellulose acetate raw sheets undergo prolonged climate-controlled conditioning to balance internal humidity, followed by high-speed computerized table cutting.
Multi-axis automated CNC routing carves precise base curves, ergonomic nose bridges, and internal lens bevel tracks tailored to prescription lens depth.
Dual-prong and 5-barrel German hinges are thermally embedded with wire-core reinforcements, securing enduring temple stability through rigorous 20,000-cycle stress tests.
Each individual frame front and temple pair is square-checked on leveling plates, adjusted for temple parallelism, and hand-wiped for dust-free pack-out.
Emerging structural pivots shaping global optical procurement and brand inventory planning.
European and North American regulatory frameworks are rapidly tightening around microplastics and phthalates. Leading optical chains now require certified bio-acetate made with non-toxic plasticizers (citric acid or vegetable-derived esters) that biodegrade within 115 days in industrial compost conditions without sacrificing tensile integrity.
High-end market demographics demand minimal front mass combined with rich aesthetic textures. Sourcing schedules are heavily favoring ultra-thin (3.0mm–3.5mm) high-density acetate (HD-Acetate) fronts fused directly with Japanese Beta-Titanium bridges and stainless steel core temples to ensure all-day ergonomic lightness.
Leading buyers are phasing out unbundled procurement models. Brands increasingly demand consolidated shipments where factory-tested frames arrive pre-packed in branded rigid drawer cases, custom microfibre pouches, and matched presentation boxes, dramatically slashing domestic handling overheads.
Essential trade, manufacturing, and logistic parameters answered by our optical engineering directors.
For ready-to-ship catalog frames, our MOQ starts as low as 100 to 300 pieces across assorted colorways. For bespoke OEM/ODM custom toolings, custom color sheet casting, and private mold extrusions, our base production run is typically 300 pieces per model, with a minimum of 100 pieces per custom colorway.
Each production batch undergoes 48-hour thermal shock cycles (-10°C to +55°C) prior to packaging to eliminate residual sheet tension. Frames are nestled in individual anti-scratch biodegradable sleeves, stabilized in high-density corrugated dividers, and packed inside moisture-sealed master cartons designed to withstand up to 100kg of vertical crush force.
Yes. We offer precise fiber laser etching, high-definition pad printing, metallic foil hot-stamping, and custom-embossed metal temple cores. You can also supply custom CAD artwork for inner metal core wires that remain distinctly visible through translucent clear or champagne-tinted acetate temples.
All optical frames, reading glasses, and sunglass components produced by our factory comply fully with ISO 12870 (Ophthalmic Optics), EN ISO 12312-1, and REACH Regulation (EC) No 1907/2006 for nickel release, skin sensitization, and dimensional stability during extended wear.
Rapid rapid-prototyping 3D resin samples take 7 business days; working hand-finished acetate counter-samples require 15 to 20 business days depending on color sheet availability. Full mass manufacturing typically completes in 45 to 60 days following formal pre-production sample sign-off.
Every optical specification follows universal lens-bridge-temple boxing standards (e.g., 53◼19-145mm). 53 represents horizontal eye size, 19 indicates DBL (distance between lenses), and 145 represents overall temple length. We calibrate bevel angles precisely to 110° to secure high-minus prescription glazing without edge blowouts.
