Explore our top OEM/ODM acetate frame series engineered with multi-axis CNC milling, hand-finished polishing, and premium Italian raw materials.
Cellulose acetate (specifically cellulose triacetate and diacetate) remains the undisputed gold standard in premium optical frame manufacturing. Derived from renewable organic sources—primarily purified cotton linters and sustainable wood pulp—cellulose acetate undergoes precise esterification with acetic anhydride, plasticized using non-phthalate compounds to engineer a bio-compatible, hypoallergenic polymer sheet.
Unlike injection-molded plastics (such as PC or basic TR90), extruded and block-cured original ODM acetate frames offer unparalleled depth of color, dynamic structural elasticity, and infinite custom polishing capabilities. Global luxury optical brands rely on original ODM (Original Design Manufacturing) acetate frame solutions to capture rich color depth, multi-layered tortoiseshell textures, and hand-carved structural ergonomics.
High-density cured acetate blocks allow optical technicians to heat-adjust frame temples and front bevels to fit individual facial contours perfectly without risking micro-fractures or shape rebound over extended operational usage.
Understanding buyer search intent and technical criteria in the international eyewear distribution ecosystem.
High intent for bold vintage geometric profiles, thick 6mm-8mm acetate faceplates, and eco-friendly bio-acetate certifications (USDA Biobased / ISO 14855 compliance). Procurement buyers demand rapid sample turnaround (<7 days) and flexible MOQ structures.
Strict adherence to CE registration, REACH chemical safety standards, and nickel-free hinge hardware. Procurement focuses on subtle organic colors, narrow oval/cat-eye geometries, and bio-degradable eco-plasticizer solutions.
Focus on lightweight hybrid constructions (Titanium front with acetate rim inserts), ergonomic Asian-fit nose pad engineering, high durability spring hinges (OBE/Visottica), and scalable OEM branding solutions.

How Shenzhen Yintai Eyewear transforms 2D design concepts into mass-manufactured, luxury retail-ready optical lines.
Our 10-person R&D team translates brand sketches into 3D parametric CAD models. Front bevel angles, temple taper curvature, and bridge balance are optimized for ergonomic fit and automated 5-axis CNC toolpaths.
High-speed CNC routers slice cured acetate blocks into exact rim shapes. Core wire shooting machines insert customized metal wire cores into acetate temples to guarantee flex control and structural rigidity.
Frames undergo a 3-stage mechanical barrel polishing cycle (bead abrasion, hardwood chip polishing, and oil finishing) followed by German OBE/Visottica hinge riveting, laser logo etching, and strict FQC verification.
Every batch leaving our Shenzhen plant undergoes rigorous physical and chemical performance verification.
Yintai Eyewear executes a strict quality management system across three distinct stages: IQC (Incoming Quality Control) verifying raw acetate sheet moisture, plasticizer composition, and alloy purity; IPQC (In-Process Quality Control) inspecting CNC tolerances and hinge alignment during assembly; and FQC (Final Quality Control) testing surface gloss, hinge resistance, and optic alignment.
Standardized international quality control operating procedures guarantee batch-to-batch consistency for large-scale enterprise buyer orders.
Fully registered for European Union market distribution, ensuring non-toxic, nickel-safe, and bio-compatible eyewear hardware.
Compliant with US import security and medical device standards for Rx prescription optical frames and sunglasses.
Direct answers to technical engineering, OEM customization, and supply chain logistics queries.
Acetate frames are produced from organic cellulose polymer sheets (cotton linters/wood pulp) that are block-cured and precision CNC machined. This provides vastly superior structural strength, deep translucent color layering, thermal heat adjustability for opticians, and hypoallergenic skin safety, whereas injection-molded plastics are brittle, prone to paint peeling, and cannot be custom-heated for frame fitting.
Our 10-person technical engineering team delivers 2D/3D CAD renderings within 24–48 hours. Once CAD designs are approved, physical sample prototypes using 5-axis CNC milling and custom hand-finishing are completed within 7 business days.
For our existing 20,000+ catalog models, we support flexible micro-orders with MOQs starting as low as 10 pieces per model for fast private label testing. For full custom ODM sheet production (custom color batching and bespoke mold development), our standard MOQ is typically 300 pieces per style across 3 color variations.
All raw acetate sheets undergo a mandatory 3-to-6 month environmental seasoning and oven-curing process to eliminate internal residual solvent stresses prior to CNC milling. This guarantees long-term dimensional stability and prevents post-manufacturing bridge or temple warping.
Yes. We offer 100% bio-based, biodegradable cellulose acetate formulations that replace traditional petrochemical plasticizers with plant-derived organic plasticizers. These frames are phthalate-free, fully compliant with ISO 14855 standards, and maintain the exact tactile feel, mechanical strength, and clarity of traditional acetate.
We partner with premier hardware suppliers including German OBE and Italian Visottica to integrate 3-barrel, 5-barrel, and high-flex spring hinges crafted from nickel-silver alloy and titanium. Hardware can be customized with custom-plated gold, silver, gunmetal, or matte PVD finishes.
We offer fiber laser etching, wire core hot-stamping, metallic logo temple inlaying, metallic foil hot-stamping, and 3D metal logo badge riveting embedded within the temple tip or temple outer faceplate.
We provide comprehensive DDP (Delivered Duty Paid), FOB, and CIF logistics services backed by full export documentation, including CE Declaration of Conformity, FDA registration codes, drop-ball impact test certificates, and RoHS material compliance sheets.
