Explore our flagship wholesale insulated drinkware engineered with double-wall copper-plated vacuum technology for supreme thermal retention and global retail compliance.
The global market for takeaway cups and mobile beverage containers is undergoing a monumental paradigm shift. Moving far beyond single-use paper or uninsulated plastic cups, modern consumers and commercial beverage chains demand high-performance, eco-friendly, and thermally efficient reusable stainless steel takeaway cups. As global environmental regulations (such as EU Single-Use Plastics Directives) tighten, brands, coffee house conglomerates, outdoor apparel leaders, and Amazon private-label sellers are actively seeking verified takeaway cup manufacturers and factories capable of delivering robust double-wall vacuum engineering, ergonomic design, and full international food-contact safety compliance.
High-quality takeaway cups must balance rigorous thermal retention (preserving heat above 65°C for over 6 hours or cold below 8°C for up to 12-24 hours) with extreme mechanical durability, lightweight portability, and aesthetically appealing exterior finishes. Achieving this requires precision deep-drawing metallurgical processes, advanced high-vacuum degassing, automated laser welding, and strict non-toxic surface powder coating systems.
Engineered with dual-layer 18/8 (SUS304) food-grade stainless steel featuring an inner copper-plated heat reflection barrier, eliminating radiant thermal transfer.
100% BPA-free, lead-free, non-toxic construction meeting FDA 21 CFR, EU LFGB, REACH, and California Proposition 65 strict toxicity benchmarks.
Complete customization from 3D design prototyping, precise PMS color matching, custom lid mold manufacturing, to laser etching and silk screen branding.
Located in the famous hardware manufacturing hub of Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd stands as a premier manufacturer specializing in the continuous research, product development, and automated mass production of top-tier food-grade stainless steel tumblers, travel mugs, outdoor sports bottles, takeaway cups, vacuum flasks, and insulated beverage containers.
Our manufacturing plant integrates both complex double-walled vacuum insulation construction and sleek single-wall structural lines. Armed with high-precision automated hydraulic pressing lines, multi-axis vacuum degassing chambers, ultrasonic eco-cleaning lines, and rigorous internal quality verification labs, Dongyi ensures every vessel leaving the factory exceeds global performance expectations.
Since our inception, our company consistently abides by our core operational tenets: "Quality First, Service First." Through decades of persistent innovation and strict supply chain discipline, we have forged strategic long-term OEM/ODM manufacturing partnerships with retail brands, importers, and distributors across North America (USA, Canada), Western & Eastern Europe, South America, the Middle East, and Southeast Asia.
Operating directly out of Zhejiang’s hardware industrial cluster grants Wuyi Dongyi unmatched supply chain resilience, raw material sourcing priority, and cost efficiencies that translate directly into competitive price advantages for global buyers. Our Smart Factory layout incorporates Industry 4.0 principles to streamline every phase of takeaway cup production.

| Vacuum Evacuation | Batch hot-pull vacuum ovens with inconsistent pressure. | Continuous high-vacuum baking chambers with real-time pressure sensors. | Consistent 24-hour thermal insulation ratings across all units. |
| Surface Finishing | Basic liquid dip paint prone to chipping and scratching. | Automated electrostatic powder coating & UV 3D digital printing lines. | Ultra-durable, dishwasher-safe coatings with scratch resistance. |
| Quality Control (QC) | Random sample testing (AQL 2.5/4.0). | 100% inline infrared temperature thermal testing + AQL 1.0 strict sampling. | Sub-0.5% defect return rate across bulk export shipments. |
To provide true Information Gain for technical procurement officers, product designers, and brand managers, the diagram and technical breakdown below outline how high-performance thermal takeaway cups achieve industry-leading temperature containment.
We utilize Austenitic 18/8 (304 grade) stainless steel containing 18% chromium and 8% nickel for the outer vessel and inner core. For specialty acidic beverages (cold brew coffee, fruit infusions, energy drinks), we offer upgraded 316-grade medical stainless steel liners to prevent electrolytic pitting and metal ion transfer.
Conduction and convection heat transfers are completely negated by evacuating air between the inner and outer walls down to $10^{-3}$ Pa vacuum pressure. Furthermore, a electroplated ionic copper layer is applied to the exterior of the inner wall to reflect infrared thermal radiation back into the liquid core.
Thermal loss overwhelmingly occurs through the cup mouth. Our specialized lid designs utilize food-safe, high-density Tritan™ (co-polyester) or PP plastic fitted with food-grade food silicone gaskets. We offer multi-functional spill-proof lids incorporating magnetic slide closures, integrated straws, and direct sip spouts.
Different market channels require specialized physical features, packaging styles, and price points. Wuyi Dongyi delivers bespoke product architectures engineered specifically for distinct sector demands.
Custom takeaway travel cups with standard barista espresso machine clearance height (fits under E61 group heads), internal fluid volume laser etch lines (8oz, 12oz, 16oz), and leak-proof quick-flip lids designed for vehicle cup holder compatibility.
Heavy-duty, rugged 32oz, 40oz, and 64oz vacuum flasks featuring sweat-free powder coat textures, ultra-durable ergonomic carrying handles, stainless steel straw accessories, and extreme thermal hold performance for camping and hiking.
Sleek, high-end gift sets including egg-shaped wine tumblers, skinny tumblers, and personalized laser-engraved corporate logos presented in custom luxury gift packaging for corporate incentive campaigns.
Navigating global customs, import regulations, and food safety standards can present significant risks to international procurement managers. At Wuyi Dongyi Dailysupplies Co., Ltd, we eliminate compliance friction by maintaining comprehensive certification records and offering direct localized support documentation.
Our products undergo rigorous testing by third-party laboratories (SGS, TUV, Intertek). We provide compliance certificates for FDA 21 CFR 175.300, EU Regulation (EC) No 1935/2004, German LFGB, and French DGCCRF.
To safeguard brand reputation for global retailers, our manufacturing facilities adhere strictly to ethical labor practices, fully certified under BSCI (Business Social Compliance Initiative) and ISO 9001:2015 quality management systems.
We offer complete flexible commercial terms including EXW, FOB (Ningbo/Shanghai), CIF, and full DDP (Delivered Duty Paid) door-to-door delivery handling customs clearance, tariffs, and inland transport directly to your fulfillment warehouse.
