Explore our benchmark custom vacuum insulated tumblers, travel mugs, and sports hydration vessels engineered for global OEM/ODM brands.
Located in Wuyi County, Zhejiang Province—the global epicenter of stainless steel hardware manufacturing—Wuyi Dongyi Dailysupplies Co., Ltd stands as an industry-leading OEM/ODM manufacturer specializing in food-grade stainless steel drinkware. We pioneer research, development, and high-volume production of unique coffee mugs, double-walled vacuum insulated tumblers, sports bottles, travel jugs, and specialized thermal containers.
Our state-of-the-art manufacturing campus integrates automated robotic lines, rigorous copper-plating vacuum isolation chambers, laser welding systems, and advanced metallurgical testing labs. Driven by an unrelenting pursuit of perfection, our engineering team transforms creative aesthetic concepts into market-dominating retail products for brands across North America, Europe, South America, the Middle East, and Southeast Asia.
Precision manufacturing backed by strict quality control systems and certified food-grade materials.
Leveraging smart manufacturing, automated robotics, and direct raw material integration to deliver unparalleled cost-efficiency, thermal precision, and rapid scalability.
We utilize premium 18/8 (SUS304) and medical-grade SUS316 stainless steel. Our raw materials undergo rigorous X-ray fluorescence spectroscopy to verify zero lead, zero toxic contaminants, and absolute corrosion resistance against acidic coffee brews.
Our high-vacuum annealing furnaces extract air down to 10^-4 Pa. With added internal copper lining technology, heat radiation is reflected back into the cup, maintaining beverage heat for 12+ hours and cold preservation for up to 24 hours.
From automatic stretch shaping and laser trimming to automated electrostatic powder coating, our Industry 4.0 infrastructure guarantees micro-level dimensional stability, eliminating human error in mass production runs.
Tailor-made structural engineering, bespoke ergonomic profiles, and advanced surface finishes for global importers, Amazon sellers, and brand owners.
Choose from durable matte powder coatings, gradient spray paints, high-gloss UV lacquers, 3D tactile textures, rubberized soft-touch coatings, and full-wrap sublimation prints designed to withstand dishwashers and daily wear.
We engineer leak-proof flip lids, 2-in-1 sip and straw mechanisms, magnetic slider covers, and ergonomic thumb-rest handles (e.g., 40oz and 30oz Hydra Quencher formats) crafted from BPA-free Tritan and food-grade silicone seals.
Elevate private label value via fiber laser engraving, silk-screen printing, embossed/debossed steel logos, water transfer printing, and customized retail color boxes engineered for e-commerce drop-shipping protection.
Submit specs, targeted capacity, and branding requirements.
Receive engineering quotes, 3D drawings, and structural render.
