Explore our premier line of OEM/ODM double-walled stainless steel travel cups, sports flasks, and tumblers engineered for global B2B procurement.
The transition from single-use plastics to eco-friendly, double-walled vacuum insulated travel cups represents a structural shift in global consumer behavior and B2B sourcing strategies.
The global demand for high-performance stainless steel travel cups is accelerating. Enterprise buyers across North America, Europe, South America, the Middle East, and Southeast Asia are prioritizing suppliers capable of providing food-grade 18/8 (304) and medical-grade 316 stainless steel vessels. Driven by strict environmental regulations banning single-use plastics and growing fitness culture, the global drinkware market is evolving beyond simple utility into lifestyle fashion statements, corporate branding assets, and specialized outdoor gear.
International procurement managers, Amazon FBA brand aggregators, and retail distributors demand more than baseline manufacturing. Success in modern OEM/ODM partnerships requires strict compliance with FDA, LFGB, and REACH standards, automated quality assurance, rapid prototyping, and hyper-customized surface finishes. Importers require transparent supply chains capable of delivering custom powder-coated colors, laser-engraved branding, leak-proof multi-functional lids, and optimized freight packing configurations.
Located in the premier manufacturing hub of Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd stands as a tech-driven industrial enterprise specialized in the research, development, and high-volume manufacturing of premium food-grade stainless steel drinkware.
Our facility spans thousands of square meters equipped with fully automated laser welding, high-vacuum pumping extraction chambers, automatic powder coating lines, and rigorous internal testing laboratories. We engineer both double-walled vacuum insulation structures and lightweight single-wall stainless steel containers engineered to perform under extreme ambient conditions.
"Quality First, Service First" drives every step of our operations. From raw 304 stainless steel coil inspection to final drop tests and thermal degradation verification, our manufacturing protocol ensures every container meets world-class retail standards.
Discover how modern automated production lines in Zhejiang provide global brands with unmatched supply chain resilience, precise vacuum retention, and zero-defect quality control.
We utilize premium 18/8 (SUS304) and medical-grade SUS316 stainless steel. Highly resistant to rust, oxidation, and chemical corrosion, ensuring zero flavor transfer and lifetime durability for acidic beverages like coffee and fruit juices.
Our double-walled vessels undergo high-vacuum evacuation at 500°C. An electroplated copper layer on the exterior of the inner wall reduces thermal radiation, maintaining hot liquid heat for 12+ hours and cold ice for 24+ hours.
Solvent-free electro-static powder coatings provide sweat-free, anti-slip textures resistant to chips, scratches, and commercial dishwasher cycles. Ergonomic handles and BPA-free Tritan co-polyester lids guarantee long-term safety.

18/8 grade stainless steel contains 18% chromium and 8% nickel, creating an austenitic crystalline structure that prevents corrosion, chemical leaching, and liquid odor retention. Unlike lower-tier 201 steel or aluminum, 304 stainless steel is food-safe, non-reactive with acidic beverages, structurally stable under heat, and 100% recyclable.
Our vacuum flasks consist of an inner and outer stainless steel vessel welded together at the neck. The air between the two walls is evacuated in high-temperature vacuum furnaces to a pressure of 10^-3 Pa, creating a near-perfect thermal vacuum. Without air molecules, heat conduction and convection are blocked. An internal copper electroplated barrier reflects radiant heat back into the bottle.
We provide extensive custom options including tailored Pantone powder coat colors, UV digital direct printing, water transfer printing, laser engraving, silk screen logos, custom outer packaging boxes, hang tags, and bespoke lid designs tailored to your functional preferences.
All Wuyi Dongyi products are manufactured using BPA-free materials and undergo rigorous third-party laboratory testing. Our drinkware fully complies with US FDA food contact specifications, European Union LFGB regulations, California Proposition 65, and REACH toxicological safety criteria.
Our standard production MOQ typically starts at 1,000 units per color/design for custom runs, though stock colors may accommodate smaller trial orders. Prototype samples are completed in 3 to 7 days, with full container mass production completed within 25 to 35 business days following sample approval.
