Wuyi Dongyi Dailysupplies Co., Ltd: Setting the Standard for OEM/ODM Stainless Steel Thermal Drinkware
Wuyi Dongyi Dailysupplies Co., Ltd is strategically located in the renowned hardware manufacturing core of Wuyi County, Zhejiang Province, China. We specialize in the end-to-end research, engineering design, and high-volume production of food-grade stainless steel tumblers, mugs, bottles, cups, jugs, and double-walled vacuum insulated containers.
Our facility integrates advanced hydraulic stretching machines, automated high-temperature vacuum sintering furnaces, robotic laser welding setups, and zero-defect quality inspection lines to serve high-tier international brands.
From our inception, we have strictly adhered to the core philosophy: Quality First, Customer Service First. We maintain active export channels and ODM custom manufacturing partnerships across North America, Europe, South America, the Middle East, and Southeast Asia.
By continuously innovating custom surface coating technologies (powder coating, sublimation, gradient painting), custom logo laser etching, and functional ergonomic lid designs, our products command exceptional market share across worldwide retail and e-commerce platforms.
Every piece of drinkware leaving our assembly lines complies with stringent international food contact regulations (CE, FDA, LFGB, REACH, CA Prop 65). We utilize premium Austenitic 304 (18/8) Stainless Steel and optional medical-grade 316 steel for superior corrosion protection and zero chemical leaching.
Our dedicated R&D engineering team collaborates directly with brand managers, corporate procurement officers, and Amazon FBA sellers to turn technical CAD concepts into mass-market bestsellers.

Data-driven manufacturing precision and key operational benchmarks for enterprise buyers seeking ODM bulk coffee mugs.
The global reusable drinkware sector is undergoing a massive structural shift away from single-use plastics and ceramic mugs toward lightweight, highly durable double-walled stainless steel vacuum insulated tumblers. Corporate enterprises, coffee chain conglomerates, and promotional product distributors require reliable manufacturing partners who can supply consistently engineered thermal retention units with short turnaround times.
By leveraging China’s hardware industrial ecosystem in Zhejiang, Wuyi Dongyi Dailysupplies Co., Ltd bridges the gap between high-volume cost efficiency and rigorous Western quality assurance standards. From high-capacity 40oz handle quenchers to sleek 20oz skinny tumblers and ergonomic 12oz egg-shaped coffee cups, our turnkey manufacturing infrastructure meets all technical specs for retail packaging, thermal longevity, and food-grade compliance.
Understanding the thermodynamics, metallurgical selection, and lid sealing mechanics behind commercial-grade insulated drinkware.
Thermal loss occurs via conduction, convection, and radiation. Our manufacturing process evacuates air between the inner (304 SS) and outer (201/304 SS) walls to a pressure below 10-3 Pa in continuous vacuum kilns. Furthermore, an ultra-thin copper plating layer is applied to the exterior of the inner flask to reflect radiant thermal energy, ensuring beverages stay boiling hot for up to 12 hours or ice-cold for 24+ hours.
The standard food-grade standard is 18/8 Austenitic Stainless Steel (SUS304), containing 18% Chromium and 8% Nickel, offering exceptional resistance against acidic coffee oils, tea catechins, and carbonated beverages. For high-corrosion or medical applications, we offer SUS316, which incorporates 2-3% Molybdenum for maximum pitting corrosion resistance.
A vacuum flask is only as good as its closure. We engineer BPA-free, food-contact safe lids using crystal-clear Eastman Tritan™, food-grade Polypropylene (PP), and platinum-cured medical silicone gaskets. Our lids feature spill-proof sliding locks, straw ports, and dual-mode sip/chug mechanisms engineered for zero leakage during transit.

Why sourcing bulk coffee mugs directly from Wuyi, Zhejiang delivers unparalleled commercial advantages to global buyers.
Wuyi County and neighboring Yongkang form the world's most dense hardware manufacturing cluster. Raw stainless steel coils, silicone seals, custom box packaging, and tooling shops exist within a 15-mile radius, drastically reducing component lead times.
Our in-house design team produces 3D CAD modeling within 24 hours and physical 3D-printed or CNC-machined samples within 3-5 days. Custom mold creation takes under 20 days, letting you capitalize quickly on trending tumbler aesthetics.
We offer exhaustive decorative finishing capabilities: matte powder coating, glossy electroplating, gradient color blending, rubberized touch spray, water transfer marble prints, full-wrap thermal sublimation, and precision laser etching.
Automated production lines cut unit labor costs while strict quality control minimizes material scrap rates. Sourcing directly from our production floor guarantees optimal wholesale profit margins for importers and distributors.
Aligning custom ODM drinkware development with evolving consumer lifestyle demands across key markets.
Modern coffee houses are shifting to branded reusable travel mugs for eco-conscious customers. Our 12oz, 16oz, and 20oz vacuum insulated mugs feature car-cup-holder friendly bases and splash-proof lids optimized for espresso drinks, lattes, and cold brews on the go.
Enterprise clients require high-end, customized corporate gifting solutions for employee onboarding, conferences, and executive kits. Laser-engraved logo tumblers with premium matte powder coating provide high brand visibility and executive value.
Large-capacity tumblers (such as 30oz skinny tumblers and 40oz handle quenchers) are dominating the outdoor, fitness, and vehicle commuting segments. Double-wall insulation prevents outer condensation ("sweating"), keeping gym bags and desk surfaces completely dry.
