Pure Titanium
Direct-from-factory optical architectures, luxury rimless pure titanium mounts, and high-impact TR90 frames ready for low-MOQ rapid customization and bulk turnkey distribution.
A rigorous industrial perspective on materials science, multi-axis micro-machining, cleanroom assembly, and the structural benchmarks that separate consumer-grade frames from high-end optical dispensary standards.
The international eyewear market demands an uncompromising balance between biomechanical ergonomics and high-volume consistency. As a preeminent Original Design Manufacturer (ODM) and Original Equipment Manufacturer (OEM) headquartered in China's prime precision manufacturing clusters, our manufacturing network integrates the engineering precision of aerospace-grade CNC tooling with the artisanal refinement of multi-stage hand finishing. Producing over 1.2 million frames each month across pure titanium, beta-titanium memory alloys, high-density cellulose acetate, and Swiss-imported Grilamid TR90 polymers, we empower independent optical chains, healthcare optometry networks, and luxury fashion houses with comprehensive product lifecycles from concept CAD rendering to finished packaged SKUs.
Processing Grade 1 & Grade 2 pure titanium alongside Japanese Beta-Titanium (Ti-15V-3Cr-3Sn-3Al). We utilize cold-drawn wire, vacuum resistance brazing, and high-frequency pulse laser welding within argon chambers to preserve crystal grain boundaries, eliminating solder joint brittleness and achieving total nickel-free biocompatibility.
Sourcing organic cotton linters and plasticizer-balanced cellulose acetate from global leaders including Mazzucchelli 1849 and top domestic polymer laboratories. Each slab undergoes mandatory kiln-curing at 55°C for 72 hours to relieve internal stress before 5-axis CNC routering and a 4-stage 96-hour tumbling sequence using organic birchwood pegs, pumice stones, and micro-crystalline wax.
Moving beyond conventional wet chemical electroplating, our physical vapor deposition (PVD) chambers apply ultra-dense titanium nitride (TiN) and zirconium coatings up to 2.5 microns thick. This delivers surface hardness surpassing 2000 HV, exceptional resistance to UV discoloration, hypoallergenic performance, and immaculate color integrity across polished gold, gunmetal, and matte black finishes.
A strategic analysis for supply chain managers, private-label optical directors, and commercial buyers seeking to derisk international manufacturing dependencies.
The international supply chain for optical products is transitioning from volume-driven transactional procurement toward intelligent, data-synchronized ODM ecosystems. Brand founders and retail consortiums are confronted with escalating regulatory hurdles, shifting retail consumer priorities regarding material traceability, and compressed merchandising collection cycles. Sourcing leaders must align with Chinese Tier-1 manufacturers that provide technological agility rather than basic assembly labor.
The legacy model of committing to 2,000 units per colorway per tooling run is obsolete. Leading ODM architectures leverage modular CNC fixtures, digital master molds, and interchangeable temple wire cores, allowing enterprise clients to execute micro-batch initial runs of 100 to 300 units per SKU to validate real-time regional sell-through without holding massive working capital reserves.
Stricter European Union Ecodesign Regulations (ESPR) and extended producer responsibility laws mandate documented material pedigrees. Forward-thinking procurement now specifies bio-based acetate formulated with plant-derived non-phthalate triethyl citrate plasticizers, achieving biodegradation under standard industrial composting conditions within 115 days (tested per ISO 14855 standards).
With smart audio eyewear and AR-assisted vision displays entering mainstream adoption, modern ODM factories must incorporate micro-electronic cavity milling directly into the temple stems and endpieces. This demands cleanroom co-molding, water-resistant IPX5/IPX7 ultrasonic welding, and precise weight-balancing calculations to ensure the optical optical center (OC) remains stationary during dynamic head movement.

Analyzing the crossover between functional ophthalmic lens accommodation and runway-inspired styling across global demographic segments.
Accommodating biometric differences between global facial contours is essential for sell-through. Our ODM CAD frameworks optimize bridge pad-arms, pantoscopic tilt (8° to 12°), and vertex distance (12mm to 14mm), engineering "Universal Fit" and "Alternative Fit" profiles that prevent frame slippage on shallower nasal bridges and lower cheekbone contact points.
As strong myopic corrections and complex free-form digital progressives surge among digital device users, our contemporary full-rim and combo architectures feature 3.8mm to 4.5mm rim profiles. This mechanical depth entirely conceals thick negative power lens bevels up to -8.00D, delivering sleek exterior silhouettes without revealing lateral edge thickness.
Combining the hyper-elasticity of Swiss Grilamid TR90 with the artisan tactile luxury of cellulose acetate. Through precision co-injection tooling and integrated metal armature skeletons, we produce ultra-lightweight hybrid structures under 12 grams that retain their adjusted shape in hot climates without bowing out of optical alignment.
Combining complete vertical supply integration, stringent laboratory test benches, and a verified export heritage to over 65 countries worldwide.
Every production batch is subject to rigorous lot acceptance sampling (AQL 1.0/2.5) within our ISO/IEC 17025 calibrated metrology laboratory. Tests include drop-ball impact resistance (FDA 21 CFR 801.410), nickel leaching analysis (EN 16128), spectrometer lens spectral transmittance, and bridge deformation fatigue resistance.
Rather than subcontracting mold manufacture, our cleanroom tooling wing operates high-precision Sodick wire EDM and Makino high-speed graphite milling centers. This enables rapid mold production in as little as 21 days with micron-accurate hinge pin alignment, ensuring smooth opening and closing resistance across thousands of cycles.
We deliver true turnkey private-label solutions. Beyond the frame itself, we offer precision laser pad-printing of batch model numbers, hot-foil core temple stamping, bespoke molded optical travel cases, micro-fiber cleaning cloths with high-density heat-transfer artwork, and retail-ready FSC-certified packaging sets.
Direct, unvarnished insights into production minimums, custom mold cycles, testing protocols, and payment security for global supply chain professionals.
