Beta Titanium Optical Frames

Beta Titanium Optical Frames utilize titanium alloys containing stabilizing elements (such as vanadium and aluminum or molybdenum) processed via solution-treatment to achieve a metastable beta-phase structure. This molecular alignment delivers extreme elasticity, high strength-to-weight ratios, and superior fatigue resistance compared to commercially pure (CP) titanium or standard monel/nickel-silver alloys.

Engineered for precision optical brands, these frames weigh between 7.2g to 14.5g (lens-excluded) and provide continuous, gentle pressure distribution across the temples without deforming. Manufacturing utilizes 5-axis CNC milling, precision wire EDM cutting, and vacuum ion plating (IP) to maintain structural integrity and a uniform surface finish across large-scale production runs.

High Elasticity Memory Temples: Beta-titanium wire and sheet retain elastic deformation up to 6% strain, allowing temples to flex outward significantly without permanent bending or snapping.

Corrosion & Sweat Resistance: Passivation treatment creates a stable titanium dioxide (TiO2) surface layer, preventing degradation from skin acidity, facial oils, and saline exposure.

Hypoallergenic Composition: Nickel-free base material complies with EU Nickel Directive standards, eliminating contact dermatitis risks for sensitive wearers.

Low Density Strength: Density of approximately 4.5 g/cm3 (40% lighter than stainless steel) maintains structural rigidity while minimizing bridge and nose-pad pressure points.

Tight Tolerances for Lens Mounting: Grooves cut via CNC profiling maintain groove width accuracy within +/-0.03 mm, securing prescription ophthalmic lenses and preventing optical axis rotation.

Front Chassis: Formed from solid beta-titanium sheet via precision stamping and 5-axis CNC milling to eliminate micro-cracks in stress concentration zones (brow bar, bridge, and endpieces).

Hinge Assembly: Integrates integrated barrel hinges or custom screwless spring systems laser-welded using Argon shielding to maintain joint shear strength above 120N.

Temple Integration: Laser-cut taper profiles ensure graduated flexibility from the hinge point to the ear tips, preventing pinch points behind the auricle.

Nose Pad Arms: Integral or laser-welded pure titanium arms designed to accept screw-on or push-in medical-grade silicone pads.

Silhouette Profiles: Full-rim, semi-rimless (nylon cord secured), and minimalist rimless mountings compatible with drill-mount or groove-mount lenses.

Standard Size Matrix: Available in bridge-lens-temple configurations including 48-18-140, 50-20-145, and 52-19-145.

Custom Geometries: Custom eyeshapes (Pantos, Square, Aviator, Cat-Eye) developed from CAD step/iges files provided by client design teams.

Surface Finishes: Brushed matte, high-polish gloss, sandblasted anti-reflective texture, and dual-tone IP plating (Gold, Gunmetal, Rose Gold, Titanium Silver, Matte Black).

CAD/CAM Engineering Support: DFM (Design for Manufacturing) analysis conducted on client 2D/3D drawings within 48 hours to identify wall thickness vulnerabilities and stress points.

Laser Branding: Custom logo etching, pad printing on temple tips, or inner-temple laser stamping of brand nomenclature and model numbers.

Prototype Turnaround: Rapid CNC-machined physical prototypes and 3D-printed resin fit-test samples delivered within 7 to 12 business days.

Tooling and Die Sinking: Dedicated stamping dies and CNC fixture programs locked exclusively for client production runs to protect proprietary designs.

Production Equipment:
30+ units of 5-axis and 4-axis CNC machining centers.
CNC laser cutting and automatic tube bending machinery.
Automatic vacuum ion plating (PVD) coating chambers.
High-precision optical comparator and profile projector measuring systems.

Quality Control Protocols:
• Material Spectrometry: Incoming raw material rods and sheets verified via positive material identification (PMI) spectrometer testing.
• Elasticity Fatigue Testing: Temples subjected to automated mechanical fatigue testing (> 15,000 open-close cycles) to verify spring tension retention.
• Corrosion Resistance: Salt spray testing (ASTM B117) executed for 72 hours to confirm plating adhesion and absence of oxidation.

• Dimensional Audit: 100% optical alignment check for lens groove symmetry, pantoscopic tilt angle, and vertex distance tolerances (+/-0.1 mm).

Certifications: Manufacturing facilities operate under ISO 9001:2015 quality management systems and CE / FDA regulatory compliance documentation for optical medical devices.

Ophthalmic Prescription (Rx) Frames: Designed to house high-index, progressive, and heavy corrective lenses without distorting the frame chassis.

Luxury & Designer Fashion Lines: Lightweight luxury collections where slender profiles and complex geometry define high-end retail positioning.

Corporate & Safety-Adjacent Daily Wear: Professional environments requiring understated aesthetic presentation combined with durable, non-fatiguing wear characteristics.

Specialized Reading & Computer Glasses: Ultra-light weight configurations designed for prolonged use without nasal indentations or ear fatigue.

Export Packaging: Each frame protected by an individual low-density polyethylene (LDPE) sleeve, secured in a blister tray, packed in inner rigid boxes (10 pcs), and consolidated into double-walled corrugated master cartons with moisture-absorbing desiccant.
