Explore our benchmark ODM lightweight frames engineered for high structural integrity, ergonomic comfort, and premium global optics distribution.
Quantifiable manufacturing excellence backed by 15 years of continuous research, CNC precision automation, and strict global quality control frameworks.
Analysis of changing consumer ergonomics, advanced polymer engineering, and global B2B procurement paradigm shifts.
Modern optical consumers demand all-day wearable comfort. The global market is transitioning from heavy traditional plastics to ultralight high-density acetate (HDA) and beta-titanium structures. Frames weighing under 15 grams have become the new industry benchmark for luxury and daily optical lines.
Global brands are moving away from generic off-the-shelf catalog sourcing toward Original Design Manufacturing (ODM). Brands require bespoke 3D CAD modeling, custom core-wire carving, and proprietary hinge mechanisms to establish defensible market positioning and high perceived brand value.
Bio-based acetate (derived from wood pulp and cotton fibers without chemical phthalate plasticizers) and recyclable pure titanium are dominating European and North American procurement protocols. Compliance with strict chemical safety standard ISO 12870 is mandatory for market entry.
| Material Type | Density / Weight Ratio | Tensile Strength | Hypoallergenic Grade | Target ODM Application |
|---|---|---|---|---|
| Pure Titanium (Grade 2/4) | Ultra-light (~12g - 15g per frame) | Exceptionally High (>450 MPa) | 100% Biocompatible | Premium Executive & Minimalist Collections |
| High-Density Acetate (HDA) | Lightweight (~18g - 24g) | High Flexibility & Mold Memory | Skin-Friendly (Biomaterial) | Retro Fashion, Bold Geometric & Square Frames |
| Beta Titanium Alloys | Ultra-light (~10g - 14g) | Ultra-High Elasticity | 100% Biocompatible | Flex-temple Sport Optical & Frameless Mounts |
| TR90 / Swiss Grilamid | Extremely Light (~11g - 16g) | Impact & Thermal Resistant | Medical Grade Polymer | Active Outdoor, Kids & Casual Daily Eyewear |
Located in Shenzhen, China – Vertically Integrated ODM/OEM Infrastructure Serving Top Global Optical Retailers.
Located in the industrial park at Fuji Land Building, equipped with: fully automated production lines, CNC machining centers, Class 10,000 cleanrooms, and more, ensuring both stable production capacity and consistent quality.
We have over 200 dedicated employees, including a 10-member elite R&D and technical team that continuously drives product innovation, tooling design, and process optimization.
From raw material procurement and mold development to finished product assembly, we have achieved complete vertical integration across core production processes. This translates to controllable costs, rapid delivery cycles, and high quality stability.
End-to-end engineered workflows tailored for high-end boutique optical brands, retail chains, and ecommerce conglomerates.
Our 10-person R&D engineering team transforms brand concepts into high-precision 3D CAD files. We optimize temple flexure angles, bridge nose pad distribution, and weight centering to guarantee comfortable wear across European, Asian, and American facial ergonomics.
Utilizing high-accuracy 5-axis CNC machines and SLA 3D printing, we deliver physical prototypes within 7 to 10 working days. This rapid prototyping stage validates hinge stress resistance, rim tension, and decorative accents like hand-carved details or diamond rivets.
Mass production takes place in our 5,000+ sqm Shenzhen facility. Cleanrooms and automated tumbling/polishing barrels ensure flawless frame surface finishing, while precision laser engraving adds custom branding, logo motifs, and model serial numbers.
Protecting global buyers with stringent international certifications, legal safety compliance, and comprehensive quality checks.
Our quality control system guarantees a 99% product pass rate before shipment.
1. IQC (Incoming Quality Control): Spectrometric testing of titanium raw bars and bio-acetate sheets for heavy metals and nickel release.
2. IPQC (In-Process Quality Control): Dimensional verification of hinge alignment, bridge curvature, and core-wire placement every 2 hours during manufacturing runs.
3. FQC (Final Quality Control): Stress durability testing (10,000+ temple flexes), drop tests, and optical alignment inspection.
All frames manufactured by Yintai Eyewear comply fully with international market access standards:
• CE Certification: Fully compliant with European Medical Device Regulation (MDR) EN ISO 12870 for spectacle frames.
• RoHS & REACH: 100% free of hazardous plasticizers, lead, cadmium, and nickel migration.
• UV400 Protection: Sun optical series filter out 100% of UVA/UVB rays up to 400nm wavelengths.
Strategic R&D initiatives driving the future of ultra-lightweight optical frame manufacturing.
Integrating graphene nano-structures into high-density acetate formulations. This tech advance reduces temple thickness to just 1.8mm while increasing structural rigidity by 35%, opening new avenues for featherlight retro-style optical frames.
Expanding our custom ODM prototyping laboratory with Selective Laser Melting (SLM) 3D titanium printing. This enables complex hollow temple geometry and screwless integrated hinges weighing under 8 grams total.
Designing ultra-light dual-purpose frames featuring micro-recessed inner temple channels optimized to house open-ear micro-speakers and Bluetooth smart components without compromising frame ergonomics or style.
Technical and commercial clarity for global purchasing managers and brand founders.
