Explore our core engineering lineup of premium food-grade stainless steel tumblers, bottles, and specialized mugs crafted for global brand distribution.
Located in the heart of China’s hardware industrial ecosystem—Wuyi County, Zhejiang Province—Wuyi Dongyi Dailysupplies Co., Ltd. stands as a premier enterprise specializing in the research, development, engineering, and mass production of high-grade stainless steel drinkware. Our product portfolio spans food-grade stainless steel tumblers, vacuum insulated mugs, sports bottles, travel cups, ice jugs, and specialized thermal containers. By mastering both double-walled vacuum insulation construction and robust single-wall structural designs, our facility satisfies the stringent standards required by international retail brands, commercial importers, and wholesale buyers across North America, Europe, South America, the Middle East, and Southeast Asia.
Operating under the unwavering principle of "Quality First, Service First," our manufacturing plant is equipped with automated deep-drawing presses, robotic laser welding stations, high-vacuum degassing furnaces, and automated powder coating lines. Every single vacuum cup undergoes rigorous multi-stage temperature testing to verify structural seal integrity, guaranteeing zero thermal leakage and superior longevity.
Our dedicated in-house R&D engineering team leverages advanced CAD/CAM software and rapid prototyping techniques to transform custom concepts into market-ready OEM and ODM solutions with minimal lead times.
The global reusable drinkware market is experiencing a profound paradigm shift. Driven by worldwide environmental regulations banning single-use plastics, alongside shifting consumer lifestyles centered around personal wellness, fitness, and hydration aesthetic trends (popularized by viral social media formats like 40oz handles and quencher tumblers), commercial buyers require flexible manufacturing partners able to adapt to sudden demand surges.
Global retail conglomerates are auditing supply chains for carbon footprints and non-toxic materials. Replacing single-use plastics with premium 18/8 food-grade stainless steel cups reduces lifecycle emissions by up to 76% over 3 years.
Modern consumers view drinkware as a fashion accessory. Large-capacity tumblers (30oz to 48oz) featuring car-cup holder compatible tapered bases, ergonomic splash-proof lids, and integrated straws dominate high-margin retail channels.
Specialized cultural products such as the double-walled insulated 8oz Yerba Mate Gourd are expanding rapidly outside Traditional South American markets into North America and Europe as outdoor wellness trends rise.
Understanding the metallurgical and thermal science behind stainless steel water bottle manufacturing is crucial for procurement managers evaluating factory capabilities. At Wuyi Dongyi Dailysupplies Co., Ltd., our engineering processes strictly regulate raw metal chemistry and thermal barrier creation.

Heat transfer occurs through three physical mechanisms: conduction, convection, and radiation. Our double-wall vacuum insulated tumblers and bottles completely eliminate internal heat transfer:
Manufacturing high-precision stainless steel drinkware requires an ecosystem capable of integrating raw material sourcing, metal forming, vacuum processing, surface finishing, and quality control. Wuyi Dongyi Dailysupplies Co., Ltd. capitalizes on the deep industrial cluster of Zhejiang Province to deliver world-class efficiency.
Multi-stage hydraulic presses stamp food-grade SUS304 sheet metal into seamless inner liners, preventing structural stress fractures and ensuring uniform wall thickness across all product shapes.
High-precision laser welding equipment seals the inner and outer shells at the rim and base. Precision joints prevent seal degradation during temperature fluctuations and dishwasher cycles.
Automated powder coating and spray lines apply durable, scratch-resistant finishes. Options include matte, glossy, metallic gradient, textured powder coating, 3D UV printing, and hydro-dipped graphic wraps.
We streamline international procurement through a structured manufacturing pipeline engineered for zero error and complete client transparency:
Submit project parameters via email or form for rapid specification assessment.
Receive competitive B2B pricing alongside 3D CAD modeling and technical renderings.
Rapid physical sample production with custom color matching and logo placement.
Automated manufacturing supported by strict in-line Quality Assurance checkpoints.
Comprehensive AQL 2.5/4.0 inspection, vacuum verification, and drop testing.
Flexible freight options (FOB, CIF, DDP) with custom eco-friendly packaging.
Relying on advanced manufacturing concepts and rigorous quality assurance, our products are distributed across North America, Europe, South America, the Middle East, and Southeast Asia.
To maximize sales conversion, importers must pair drinkware geometry with specific consumer usage contexts. Our design engineering team customizes physical dimensions, handles, and lid functionalities tailored to distinct end-user markets:
Our 30oz, 35oz, and 40oz insulated quencher tumblers are engineered with a specialized narrow tapered base designed specifically to fit standard vehicle cup holders seamlessly, catering to urban drivers and long-distance travelers.
Heavy-duty sports flasks ranging from 32oz to 64oz feature reinforced double-wall bases, wide-mouth openings for ice filling, leak-proof carabiner lids, and rugged powder-coated exteriors built to survive tough wilderness environments.
Our 8oz Mini Insulated Yerba Mate Gourds are crafted with an specialized ergonomic curved silhouette that retains hot water temperatures for traditional Mate brewing while remaining cool to the touch on the outside.
Essential technical and commercial insights for purchasing managers, importers, and brand owners considering direct factory sourcing from China.
