TR90 & Memory Hybrid
Product Specifications
As global retail optometry pivots toward maximum comfort, ultra-lightweight durability, and hypoallergenic longevity, memory metal (Nickel-Titanium / NiTi shape memory alloy and Beta-Titanium) has established itself as the elite baseline for modern prescription frames. With integrated vertically synchronized casting, multi-axis micro-CNC profiling, and vacuum ion PVD finishing, we deliver certified OEM/ODM manufacturing solutions to tier-one private labels, boutique brand owners, and multinational optical distribution networks worldwide.

Understanding the molecular martensitic transformation phase that grants shape-memory frames infinite reset capability under structural torque.
Standard metal frames experience permanent mechanical deformation past their plastic yield limit. In contrast, our medical-grade Nitinol memory bridges operate via reversible stress-induced phase transition between austenitic crystal lattice structures and martensitic shearing, ensuring complete geometric recovery even when twisted 180°.
By precisely manipulating the stoichiometric nickel-to-titanium ratio (typically 55.8 wt.% Ni) alongside cryogenic annealing cycles, our metallurgical engineers lock transformation transition temperatures (Af) strictly within ambient human ranges (0°C to 35°C), ensuring constant super-elastic flex during winter chills or desert heat.
Nickel release complies rigorously with EU REACH directives and EN ISO 12870 bio-compatibility standards. Every batch undergoes ultrasonic electro-polishing followed by vacuum Physical Vapor Deposition (PVD) titanium nitride or ion-plated color layers, offering maximum sweat resistance and zero galvanic corrosion.
| Material Spec | Yield Strength (MPa) | Elastic Strain Limit | Density (g/cm³) | Corrosion Resistance | Target Board Segment |
|---|---|---|---|---|---|
| Super-Elastic NiTi Alloy | 850 – 1100 | Up to 8.0% | 6.45 | Exceptional (Passivated) | Active Lifestyle / Resilient Bridge |
| Beta-Titanium (Ti-15V-3Cr-3Sn-3Al) | 900 – 1200 | Approx. 1.8% | 4.75 | Total Immunity | Ultra-Thin Temples & Screwless Eyewear |
| Pure Titanium (Grade 2) | 350 – 480 | Approx. 0.5% | 4.51 | Total Immunity | Hypoallergenic Luxury Chassis |
| Conventional Monel / Nickel Silver | 280 – 450 | < 0.3% | 8.80 | Moderate (Requires heavy plating) | Low-Cost Budget Spectacles |
Strategic supply chain insights for wholesale procurement directors and optical chain merchandisers planning multi-season frame board rotations.
The marketplace is rapidly abandoning monolithic frame builds. Modern consumers demand structural warmth with high-tech resilience. Procurement volumes are migrating toward hybrid composite designs: high-density Italian/Japanese bio-acetate fronts anchored by micro-laser-welded memory metal bridges and beta-titanium temples, achieving featherweight performance under 12 grams.
Screw loosening remains the primary reason for retail optometry returns and post-sale friction. Procurement trends indicate an 84% surge in demand for patented friction-lock and cylindrical screwless hinges machined directly from super-elastic memory wire, eliminating thread wear and extending product lifecycle beyond five years of uninterrupted daily wear.
With stringent global carbon accounting and supply chain transparency regulations entering enforcement, tier-one optical retail partners require documented supply chains. Forward-thinking China manufacturers are deploying certified closed-loop titanium recovery and zero-discharge electro-plating lines to ensure full audit compliance for European and North American distributors.
Combining European artistic restraint and ergonomic engineering with China's world-class precision scaling and vertically integrated supply chains.
Recognizing that independent optical chains require differentiation rather than mass-market saturation, we offer agile prototyping cycles. From 3D CAD/CAM ideation sketches to rapid steel tooling and functional samples, we complete sampling within 14 working days, supporting tiered low-MOQ batch configurations.
Unlike standard frame factories that outsource glazing, our manufacturing complex integrates class-10,000 cleanroom optical lens production. We supply matched 1.56, 1.61, and 1.67 index blue-cut, hydrophobic, anti-reflective single-vision and progressive blanks directly fitted to frames, dramatically slashing assembly and landing costs.
Every memory metal component undergoes aggressive environmental stress screenings: 30,000-cycle bridge flexion endurance, 48-hour artificial sweat immersion, 500-gram hinge torque friction testing, and spectrophotometric cross-hatch paint adhesion analysis to guarantee flawless long-term performance.
