Explore our top-rated, precision-engineered stainless steel vacuum insulated bottles, tumblers, and leisure drinkware manufactured to global compliance standards.
Combining advanced metallurgical engineering, strict quality control systems, and innovative OEM/ODM solutions to power global retail brands, importers, and enterprise distributors.
Situated in the industrial heartland of Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd. stands as a premier manufacturing facility specializing in research, design, production, and worldwide export of food-grade stainless steel tumblers, vacuum flasks, sports bottles, coffee mugs, and thermal jugs. Operating with double-walled vacuum insulation as well as durable single-wall constructions, our state-of-the-art facility integrates advanced hydraulic shaping, automated vacuum pumping, electrostatic powder coating, and precision testing equipment.
Our commitment to excellence is anchored in a rigorous, multi-stage Quality Management System (QMS). From raw 18/8 (304 grade) stainless steel coil inspection to vacuum seal integrity verification via infrared thermal sensors, every batch undergoes standardized testing for corrosion resistance, thermal retention performance, drop-impact durability, and coating adhesion. Our experienced R&D unit continually updates product geometries to meet modern ergonomics and functional lid engineering demand.
Leveraging deep industrial clusters in Zhejiang to deliver superior cost performance, rapid turnarounds, and unmatched manufacturing flexibility.
Located within the famous Wuyi-Yongkang hardware processing corridor, our factory benefits from immediate access to premium raw material suppliers, specialized tooling workshops, surface finishing houses, and logistics hubs. This geographical proximity reduces lead times for raw materials by up to 40% compared to isolated manufacturers, translating into rapid turnaround for large-scale international enterprise orders.
We provide full-spectrum OEM and ODM services. Whether your market requires custom PMS color-matched powder coatings, 3D tactile laser etching, hydro-dipped aesthetic graphics, or bespoke lid molds (such as multi-way drink spouts, straw-lock mechanisms, or leak-proof magnetic sliders), our engineering team transforms concepts into production-ready prototypes in record time.
By pairing high-speed automated robotic welding and copper-plating lines with lean manufacturing workflows, we mitigate labor overhead while elevating product stability. Global clients benefit from highly competitive factory-direct pricing without sacrificing strict compliance standards required by high-end North American and European retail networks.
An in-depth breakdown of technical standards engineering specs integrated into our premium product line.
Our flagship product line utilizes high-vacuum insulation technology. A vacuum layer created between the inner wall (18/8 304 Grade Stainless Steel) and outer wall virtually eliminates heat transfer via conduction or convection. Furthermore, an internal electro-plated copper layer reflects radiant thermal energy, ensuring cold beverages remain chilled for up to 36 hours and hot drinks stay steaming for over 12 hours.
Inner Wall: Premium Austenitic Food-Grade 304 (18% Chromium, 8% Nickel) Stainless Steel. Impervious to rust, chemical leaching, and flavor transfer.
Lid System: BPA-Free, Non-Toxic Polypropylene (PP) and AS resins featuring food-grade silicone sealing gaskets engineered to withstand extreme temperatures without degradation.
We employ durable surface finishing techniques including matte and glossy powder coating, rubberized soft-touch paint, electroplated metallic gloss, matte finish sub-dyes, and full-wrap gradient sublimation. Coatings pass rigorous 100-grid cross-hatch scratch testing and commercial dishwasher validation cycles.
Tailoring drinkware solutions to distinct regional markets, lifestyle requirements, and international safety frameworks.
Navigating global market regulations requires complete transparency. Our export drinkware products strictly comply with key global standards, including:
Different markets mandate tailored product footprints:
Staying ahead of consumer shifts towards eco-conscious materials, modern colorways, and smart hydration accessories.
Global bans on single-use plastics continue to drive double-digit growth in reusable stainless steel drinkware. Enterprise buyers are increasingly demanding recycled 304/316 stainless steel (PCR - Post Consumer Recycled steel) and eco-friendly mono-material packaging options to satisfy ESG standards.
Drinkware has evolved from simple utility to a core personal fashion statement. Color forecasting shows high consumer demand for pastel tones, iridescent electroplating, tactile silicone accessories, dual-function lids, and ergonomic soft-touch handles that blend fitness, work, and travel lifestyles.
Modern consumers seek versatile drinking experiences. We are pioneering integrated lid designs that switch seamlessly between a high-flow drinking spout, a direct sip hole, and a sealed straw mechanism—all rendered leak-proof via precision silicone engineering.
