Explore our tier-1 manufactured vacuum insulated tumblers, double-walled mugs, and high-performance commercial beverage containers designed for global brands.
The global commercial drinkware and cafe cup market has experienced a fundamental structural shift over the past decade. Driven by modern urban mobility, stringent environmental regulations on single-use plastics, and heightened consumer demand for thermal performance, high-grade stainless steel cafe cups have evolved from simple beverage vessels into critical lifestyle and enterprise branding platforms.
Governments across North America, Europe, and the Asia-Pacific region are enacting strict ESG framework policies prohibiting disposable paper and plastic cups. Commercial coffee chains, hospitality conglomerates, and corporate offices are rapidly adopting high-density 304 and 316 stainless steel cafe cups to minimize operational carbon footprints.
Modern consumers demand thermal preservation standardizing at maintaining cold liquids under 8°C for 24 hours and hot coffee over 65°C for 12 hours. Advanced copper-plated double-walled vacuum insulation has emerged as the definitive global technological benchmark.
Direct-to-Consumer (DTC) beverage brands and Amazon seller eco-systems demand high agility from OEM/ODM factories. Bespoke surface finishes—including powder coating, gradient 3D UV printing, and leakproof multi-drinking lids—are paramount for market differentiation.
Located in Wuyi County, Zhejiang Province, China—the global epicenter of stainless steel hardware manufacturing—Wuyi Dongyi Dailysupplies Co., Ltd has established itself as an industry leader specialized in the research, development, and mass manufacturing of food-grade stainless steel drinkware.
Our expansive industrial facility integrates automated deep-drawing hydraulic presses, high-vacuum degassing ovens, automated electrostatic powder coating lines, and rigorous multi-stage laser welding stations. We manufacture both double-walled vacuum insulation constructions and single-wall stainless steel cups, catering to tier-1 international brands, wholesalers, and retail giants.
Our continuous investment in R&D guarantees low thermal dissipation coefficients, zero-leakage lid seals, and long-lasting aesthetic finishes engineered for harsh commercial washing cycles.
To achieve unmatched temperature retention and structural longevity, our engineering team deploys cutting-edge thermodynamic principles and high-grade stainless steel metallurgy.

Our thermal tumblers undergo a multi-hour evacuation process in industrial vacuum furnaces operating at 10-4 Pa pressure and 600°C temperatures. This process completely strips interstitial gas molecules between the inner and outer stainless steel walls, stopping conductive and convective heat transfers.
Heat radiation is mitigated by electro-plating a precision micro-layer of pure copper over the exterior surface of the inner steel lining. This thermal mirror reflects radiant heat back into the liquid, boosting hot and cold preservation metrics by over 30% compared to non-plated alternatives.
Lids are molded using non-toxic, 100% BPA-free, high-clarity Tritan™ and polypropylene (PP) polymers. Fitted with food-grade silicone compression seals, our lids provide 360-degree spill-proof protection, customizable flip-top straw mechanisms, and slide-lock drinking ports.
We streamline OEM/ODM product development for multinational coffee networks, outdoor outfitters, and high-volume importers via our standardized 6-step manufacturing methodology.
Submit your design blueprints, capacity specs (e.g., 20oz, 30oz, 40oz, 48oz), surface coating preferences, and target performance metrics.
Receive comprehensive technical data sheets (TDS), Cost-of-Goods breakdown, and rapid 3D printed sample prototypes within 3 to 5 business days.
Upon design validation, our tooling department crafts high-precision stamping and hydro-forming dies to guarantee structural accuracy to within ±0.05mm.
Stainless steel tube expanding, laser seam welding, double-wall assembly, vacuum furnace baking, and copper coating are executed on automated lines.
Apply custom powder coatings, rubberized matte coats, water-transfer prints, or electroplated finishes alongside laser engraved or screen-printed brand logos.
Every batch undergoes thermal camera vacuum testing, leak detection, drop impact trials, and ISO-compliant packaging prior to global port dispatch.
Active Export Footprint Across North America, Western Europe, South America, the Middle East, and Southeast Asia.
Our diverse drinkware catalog is customized to fulfill distinct functional requirements across global consumer touchpoints.
Our 20oz and 30oz vacuum tumblers feature tapered base profiles engineered to fit standard automotive cup holders. Commercial coffee chains utilize our scratch-resistant powder coatings to ensure corporate logos remain vibrant through repetitive daily use.
The 40oz and 48oz high-capacity tumblers with heavy-duty ergonomic handles and straw lids cater to outdoor sports enthusiasts, gym-goers, and long-distance commuters requiring ice-cold water preservation for over 36 hours.
Our Swig Egg-Shape cups and skinny tumblers serve as luxury promotional merchandise. With custom pantone color matching and sleek metallic electroplating, corporations leverage our OEM services for high-impact brand visibility.
Key technical, quality control, and supply chain insights for global procurement managers evaluating cafe cup manufacturing partners.
We strongly recommend Food-Grade 18/8 (SUS304) stainless steel for standard commercial applications. SUS304 contains 18% chromium and 8% nickel, providing high corrosion resistance against acidic espresso shots, acidic fruit teas, and dairy solutions. For medical or ultra-premium marine environments, we offer SUS316 stainless steel with added molybdenum.
Every tumbler passes through a 3-stage thermal inspection: 1) Thermal imaging during furnace exit to identify thermal leakage; 2) Post-assembly hot water immersion temperature sensing; 3) Statistical sampling under high-pressure mechanical stress to guarantee a vacuum degradation rate under 0.2% over a 10-year lifespan.
Our standard MOQ for stock color models is 500 units. For custom pantone color matching, specialized powder coating textures, or laser engraved logos, the MOQ is 1,000 to 2,000 units. Bespoke plastic lid injection molds require an evaluation by our design team with flexible mold tooling terms.
Yes. All materials—including stainless steel body, Tritan/PP lids, and silicone gaskets—are certified compliant with US FDA 21 CFR, European Union EU 10/2011, and German LFGB food contact material standards. Full chemical migration reports are issued with each production batch.
