Explore our flagship vacuum-insulated products available for custom ODM color matching, private labeling, and global bulk supply.
Located in the renowned hardware manufacturing hub of Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd stands as an industry-leading OEM and ODM manufacturer specializing in premium food-grade stainless steel drinkware. Our expertise encompasses the end-to-end research, industrial design, thermal engineering, and automated mass manufacturing of double-walled vacuum-insulated and single-walled bottles, tumblers, mugs, flasks, and ice buckets.
By fusing advanced mechanical metallurgy with state-of-the-art color application technologies, we provide global B2B procurement partners—ranging from Fortune 500 consumer brands to hyper-growth e-commerce sellers—with bespoke ODM solutions that meet rigorous international quality metrics.
We exclusively utilize food-grade AISI 304 (18/8) austenitic stainless steel for inner liners, ensuring 100% rust prevention, zero metal leaching, and complete taste neutrality. Our proprietary double-wall vacuum extraction process achieves internal pressures below $10^{-3}$ Pa, complemented by internal copper-plated thermal radiation barriers for superior temperature retention exceeding 24 hours cold and 12 hours hot.
A comprehensive technical analysis of custom surface treatment methods engineered for maximum durability, aesthetic appeal, and brand differentiation.
Utilizes dry polymer powder applied via electrostatic spray, baked at high temperatures ($200^\circ\text{C}+$) to form a textured, scratch-resistant barrier. Offers superior grip, chip resistance, and zero VOC emissions, ideal for heavy-duty outdoor and fitness application scenarios.
Liquid liquid-paint finishing engineered for ultra-smooth tactile feedback. Supports multi-tone vertical or horizontal gradient color blending. Achieves exact Pantone Matching System (PMS) color fidelity with precise sheen levels from high-gloss to ultra-matte (0-5% gloss index).
High-vacuum plasma coating technique depositing thin metal films (e.g., Titanium, Chrome, Gold) directly onto the stainless steel matrix. Yields hyper-reflective metallic luster with exceptional surface hardness (up to 2000 HV), immune to tarnishing and chemical degradation.

Aligning manufacturing capabilities with the strategic requirements of international brands, wholesale distributors, and retail supply chains.
In mature markets such as North America and Western Europe, hydration vessels have evolved from functional outdoor gear into high-visibility lifestyle accessories. Corporate buyers require ODM suppliers capable of rapidly developing custom color palettes matching seasonal consumer trends. Dongyi leverages automated color-dispensing systems alongside custom toolings for lid mechanisms, handles, and silicone boot accessories, allowing brands to launch proprietary product lines that command premium retail margins.
Mass-market retail channels demand stringent inventory cadence and zero-defect quality control. Our manufacturing infrastructure incorporates automated robotic welding, multi-stage ultrasonic degreasing, and inline laser marking. This industrial setup eliminates production bottlenecks, enabling reliable lead times for volume purchase orders ranging from 1,000 units to multi-container shipments, minimizing stockout risks for global distributors.
How our strategic geographical positioning unlocks unparalleled cost efficiencies, raw material stability, and rapid technological innovation.
Situated within the Zhejiang stainless steel hardware belt, Dongyi sources premium 304/316 steel coils directly from tier-one steel mills. Immediate access to local specialized suppliers for silicone seals, BPA-free Tritan lids, and recycled packaging reduces raw material transit time to under 24 hours.
Our in-house CNC mold engineering shop creates custom ODM bottle profiles, ergonomic handles, and leak-proof lid molds with micrometer-level precision. Rapid 3D printing rapid prototyping allows physical sample validation in as fast as 3 days from CAD approval.
Proximity to Ningbo and Shanghai ports enables streamlined export logistics. We offer full export documentation, container loading consolidation, and flexible shipping terms including FOB, CIF, DDP, and DAP directly to global client fulfillment warehouses.
Guaranteeing safety, structural integrity, and international market readiness for every manufactured unit.
All products undergo rigorous laboratory testing to comply with global food safety regulations. Materials are verified 100% BPA-free, Phthalate-free, and Lead-free. Testing protocols align strictly with FDA 21 CFR 175.300 standards in the United States and LFGB (Sections 30 & 31) in Germany and Europe.
Our quality management framework follows ISO 9001:2015 directives across six key control gates: Raw Material Inspection, Shell Hydro-Forming Verification, Vacuum Seal Integrity Testing (100% automated chamber test), Surface Coating Adhesion Testing, Assembly Leak Checks, and Final Packaging Audits.
Wuyi Dongyi operates with social and environmental accountability. Our manufacturing facility undergoes regular third-party audits for BSCI (Business Social Compliance Initiative) and ISO 14001 environmental management system compliance, satisfying the corporate governance criteria of global enterprise buyers.
