Explore our high-demand OEM optical frames & sunglasses engineered for international wholesale clients.
In global luxury optical retail, black sunglasses remain the timeless anchor revenue driver across all demographic segments. Sourcing from certified OEM/ODM manufacturers requires deep technical validation of frame ergonomics, UV protection standards, and material longevity.
Global procurement intent has shifted from pure low-cost manufacturing toward Information Gain: verified structural durability, eco-friendly cellulose acetate, and guaranteed optical precision (UV400 / CAT 3 polarized filters).
Modern B2B buyers mandate specialized black finishes: high-density Italian Mazzucchelli acetate, ultra-light Japanese Beta Titanium, and scratch-resistant matte PVD vacuum coatings engineered for luxury aesthetics.
Demonstrating technical expertise through ISO9001 certified manufacturing, zero-defect IPQC inspection protocols, and full compliance with CE, FDA, ANSI Z80.3, and REACH environmental mandates.

Why Tier-1 global eyewear brands partner with Shenzhen-based factories for premium black sunglasses manufacturing.
Our strategic location in Shenzhen provides direct access to high-grade bio-based cellulose acetate (Mazzucchelli, JINYU) and 100% pure Japanese titanium blocks. This raw material advantage guarantees deep black color depth, high elasticity, and hypo-allergenic properties for sensitive skin types.
Utilizing multi-axis CNC machines operating at tolerances within ±0.02mm, we carve intricate temple details, bevel edges, and ergonomic bridge contours. Modern automated polishing cycles yield deep luster jet-black surfaces that resist UV degradation and chemical corrosion.
OEM black sunglasses require superior optics. We integrate Category 3 polarized TAC lenses, CR39 optical sun lenses, and Polycarbonate shatterproof lenses featuring double-sided hydrophobic anti-reflective coatings with 100% UVA/UVB blocking up to 400nm.

Leading the next generation of smart manufacturing and eco-conscious optical design.
As corporate ESG directives mandate sustainable sourcing, Yintai Eyewear is pioneering the integration of Bio-Acetate—produced from organic plant cellulose and phthalate-free plasticizers. Bio-acetate frames offer identical color depth and polishing capability as traditional acetate while biodegrading in under 180 days under industrial composting conditions.
Integrating 3D facial scanning data to optimize frame weight distribution across nasal bridges and ear contact points. We are also collaborating with consumer electronics brands to manufacture lightweight black titanium chassis designed to house micro-audio Bluetooth components and smart prescription lenses without compromising frame aesthetics.
Essential guidance for purchasing directors, product managers, and eyewear importers.
For custom acetate frames, our standard MOQ starts at 300 to 500 pieces per style/color model. For pure titanium frames or standard models with custom laser logo branding, flexible lower MOQs starting from 10 to 100 units can be arranged depending on stock component availability.
We source premium acetate sheets from verified raw material producers (such as Mazzucchelli) using standardized chemical color codes. Every material batch undergoes spectrophotometer color matching and environmental heat tests to prevent discoloration or yellowing over time.
Yes. We offer rapid prototyping services. Rapid 3D SLA physical samples can be produced within 72 hours, while hand-finished pre-production samples in exact acetate or titanium materials take approximately 7 to 15 business days.
Our sunglass products comply with international standards including CE EN ISO 12312-1, US FDA 21 CFR 801.410 (Drop Ball Impact Test), ANSI Z80.3, and Australian AS/NZS 1067.1 standards for 100% UV400 protection.
Standard lead time for mass production of acetate frames is 45 to 60 days following sample approval. Titanium frames require approximately 50 to 65 days due to complex vacuum plating and multi-axis CNC carving procedures.
We implement strict ISO9001 IQC, IPQC, and FQC protocols to maintain a 99%+ pass rate. In the rare event of manufacturing defects, all affected units are replaced free of charge under our 12-month quality guarantee policy.
