Eyewear Frames OEM Quality Verification & MOQ Guide 2026: Acetate, Titanium & TR90 | SCM Group HK

China remains the world's leading manufacturer of eyewear frames in 2026, producing over 60% of global optical and sunglass frame output. For international brands and retailers seeking OEM manufacturing partnerships, understanding quality verification processes and MOQ requirements is essential to sourcing frames that meet market standards. The three dominant premium materials—acetate, titanium, and TR90—each require distinct quality verification protocols. Acetate frames must pass dimensional stability tests, hinge torque measurements, and color fastness evaluations. Titanium frames require corrosion resistance verification per ISO standards and hypoallergenic certification. TR90 thermoplastic frames undergo flexibility testing, low-temperature resistance evaluation, and UV stability checks. Industry standard compliance includes EU EN ISO 12870 and US ANSI Z80.1 guidelines. SCM Group HK specializes in custom eyewear frame sourcing, connecting brands with verified Chinese manufacturers offering competitive MOQs and rigorous quality assurance processes.

Quality Verification Standards for Acetate, Titanium, and TR90 Frames

Each eyewear frame material demands specific quality verification tests before shipment approval. Acetate frames require dimensional inspection with temple length tolerance of ±1mm, hinge cycle testing (minimum 2,000 open/close cycles), chemical resistance to perspiration and cosmetics, and color uniformity across batches. Titanium frames must demonstrate Grade 1 or Grade 5 titanium purity, salt spray corrosion resistance for a minimum of 96 hours per ISO 9227, and weld joint strength testing for full-rim designs. TR90 frames undergo flexibility testing at -20°C to verify cold-weather performance, UV exposure resistance per ISO 4892, and tensile strength verification. All materials are evaluated against EU EN ISO 12870 and US ANSI Z80.1 for optical performance compliance. SCM Group HK's quality control team conducts pre-shipment inspections covering all these criteria to protect buyers from substandard deliveries.

MOQ Requirements and Customization Options in 2026

MOQ requirements for OEM eyewear frames from Chinese manufacturers in 2026 typically start at 300 pieces per style per color for acetate and metal/titanium designs. TR90 injection-molded frames may offer lower MOQs of 200 pieces per style due to shorter setup times. For private label or custom logo programs, manufacturers offer multiple branding options: laser engraving (preferred for metal and titanium), silk screen printing (for acetate and TR90), pad printing, and hot stamping. Lead times for standard catalog designs with custom logos run 30–45 days, while fully custom designs requiring new molds add 15–30 days. SCM Group HK can consolidate orders across multiple styles to help buyers reach MOQ thresholds, reducing per-unit costs while maintaining rigorous quality standards across all production batches.
