Pure Titanium Optical Frames

Pure Titanium Optical Frames are manufactured from 99.4% commercially pure titanium (CP Titanium, Grade 1 and Grade 2), containing zero nickel or heavy metal alloys. Engineered for high-end optical brands, private label distributors, and designer collections, these frames maintain an average weight of 12 to 18 grams per unit. The material delivers high tensile strength, absolute resistance to sweat and saline corrosion, and full biocompatibility. Production relies on precise laser cutting, 5-axis CNC milling, and vacuum ion plating (IP) to ensure structural stability across commercial production batches.

Hypoallergenic Composition: Certified nickel-free formula prevents skin irritation and contact dermatitis, complying with EU Nickel Directive regulations.

Structural Memory & Elasticity: Pure titanium provides controlled flexibility, allowing the frame front and temples to return to original alignment after mechanical stress.

Corrosion Resistance: Withstands continuous exposure to human perspiration, cosmetics, seawater, and UV degradation without surface oxidation or pitting.

Ultra-Lightweight Profile: Reduces bridge and temple pressure points, weighing 30% to 40% less than standard monel or stainless-steel frames.

Precision Laser Welding: Components are joined via argon-shielded laser welding to preserve uniform crystalline structure and eliminate brittle solder joints.

Vacuum Ion Plating (IP): Physical Vapor Deposition (PVD) bonds color molecules directly into the titanium substrate, preventing peeling, fading, or scratching during daily use.

Front Chassis: Stamped from titanium sheet plates using 300-ton hydraulic presses, followed by 5-axis CNC milling to cut precise bevel grooves for optical lens mounting.

Hinge Integration: Features custom barrel hinges integrated directly into the frame structure or laser-welded with high-strength beta-titanium screw housings to resist thread stripping.

Bridge Architecture: Monoblock or soldered bridge designs reinforced with internal stress-relief annealing to prevent structural warping during optician lens insertion.

Temple Arms: Core-formed from lightweight titanium wire or stamped strips, tapered to 0.8mm thickness behind the ear for balanced pressure distribution.

Nose Pad Arms: Pure titanium pad stems welded to the eyewire, paired with medical-grade silicone or titanium screw-in/push-on nose pads.

Silhouette Profiles: Full-rim, semi-rimless (nylor with nylon cord grooves), and minimalist rimless mountings.

Geometric Shapes: P3, round, square, pilot/navigator, rectangular, and custom geometric contours matched to brand specifications.

Standard Dimensions (mm):
• Eye Size (Lens Width): 48mm, 50mm, 52mm, 54mm
• Bridge Width: 18mm, 20mm, 22mm
• Temple Length: 140mm, 145mm, 150mm

Surface Finishes: Matte brushed, mirror polished, satin blasted, and multi-layer Vacuum Ion Plating (IP Gold, IP Gunmetal, IP Rose Gold, IP Black, and Raw Titanium).

CAD/CAM Engineering: Direct translation of STEP/IGES files into tooling paths; structural optimization for wall thickness and bend radii.

Laser Engraving: Custom branding, model numbers, and eye/bridge sizes laser-etched onto inner temples and bridge backs with controlled depth.

Custom Tooling Development: Proprietary mold opening for unique eyewire cross-sections, custom endpieces, and exclusive bridge geometry.

Prototyping Protocol: 3D-printed resin mockups followed by CNC-machined working titanium functional samples within 15 working days.

Packaging Customization: OEM hard cases, microfiber pouches, branded cleaning cloths, and custom outer carton labeling printed to specifications.
 

Production Equipment: 12 sets of 5-axis CNC machining centers, 8 precision laser cutting units, automated argon laser welding workstations, and computerized vacuum IP plating chambers.

In-House Quality Control Protocol:
• Dimensional Inspection: 100% optical comparator and digital caliper checks on bridge width, diagonal sizing, and lens groove depth.
• Plating Adhesion Test: Cross-cut tape test (ISO 2409) performed on finished sample lots to verify coating bond strength.
• Hinge Fatigue Testing: Mechanical arm actuation test running 10,000 open-close cycles to evaluate spring hinge tension retention and screw stability.
• Corrosion Chamber Test: 48-hour neutral salt spray test (ASTM B117) to verify zero oxidation or discoloration on plating interfaces.

Compliance Standards: Facilities operate under ISO 9001 quality management systems; products comply with CE (EU MDR 2017/745 optical regulations), FDA medical device listing standards, and RoHS requirements.

Prescription Optical Corrective Wear: Daily-wear optical frames for independent retail opticians, optical chains, and direct-to-consumer (DTC) eyewear brands.

Prescription Sunglasses: Sunwear collections utilizing polarized or tinted sun lenses fitted into durable titanium chassis.

Corporate & Institutional Programs: Lightweight, uniform eyewear solutions for specialized personnel requiring high durability and professional aesthetics.

Luxury Private Label Lines: High-end boutique collections requiring advanced material positioning and hypoallergenic certification.

Packaging Details: Each frame is individually sleeved in a protective polybag, housed in a custom branded hard case, packed in an individual unit box, and bulk-shipped in heavy-duty double-wall corrugated master cartons (50 or 100 units per master carton).

Minimum Order Quantity (MOQ): 300 pieces per model, split across up to 3 colorways (Minimum 100 pieces per colorway).

Sample Lead Time: 10 to 15 working days for existing tooling samples; 25 working days for custom prototype tooling development.

Bulk Production Lead Time: 45 to 60 calendar days following sample approval and deposit receipt.

Shipping Terms: FOB Shenzhen / EXW / CIF via air express (DHL/FedEx) for samples and bulk air/ocean freight for commercial orders.
