Located in the renowned hardware industrial hub of Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd is an industry-leading manufacturer specializing in the research, development, and high-volume precision production of premium food-grade stainless steel drinkware. Our expertise encompasses double-walled vacuum insulation constructions, single-walled utility vessels, thermal travel coffee mugs, sports flasks, and custom ergonomic containers.
Backed by state-of-the-art automated production lines, laser-welding equipment, stringent vacuum testing machines, and a rigorous ISO-compliant quality management system, our dedicated R&D engineers consistently drive technical innovation. From structural ergonomics to advanced thermal barriers, we provide global brand owners, importers, Amazon sellers, and corporate buyers with scalable, turn-key OEM and ODM solutions.
Leveraging automated robotic engineering and localized supply chain clusters in Zhejiang to achieve unbeatable lead times, strict cost control, and uncompromising quality.
Utilizing multi-stage vacuum degassing furnaces operating at over 1000°C to strip all residual gas molecules between double walls, ensuring optimal thermal retention for up to 24 hours cold and 12 hours hot.
Seamless 360-degree laser seam welding eliminates micro-fractures along cup rims and base joints, enhancing impact resistance and aesthetic elegance while eliminating potential leak pathways.
Every single travel coffee mug undergoes automated temperature testing via infrared thermal imaging sensors combined with helium mass spectrometer leak detection before moving to surface finishing.
Setting the industry standard for thermal performance, ceramic interior linings, and smart eco-coatings.
We utilize high-purity austenitic 18/8 (SUS304) stainless steel as our foundational core material, offering superior resistance against oxidation, acid corrosion, and mechanical stress. For specialized pharmaceutical or specialty coffee applications, we offer internal walls upgraded to SUS316 stainless steel with added molybdenum for ultra-corrosive liquid stability.

Navigating international safety standards is paramount for global brand expansion. At Wuyi Dongyi Dailysupplies Co., Ltd, all products undergo rigorous chemical, physical, and food-contact testing in accordance with market destination rules.
Direct answers to crucial procurement inquiries for global buyers, importers, and brand managers.
Our standard MOQ for OEM customized powder coating, logo printing, or custom color matching is typically 1,000 to 3,000 units per model, depending on the vessel capacity and complexity of surface finish. For stock colors or standard models, smaller trial quantities can be accommodated.
Yes. All our travel mugs, coffee tumblers, and flasks are manufactured using premium food-grade SUS304 (18/8) stainless steel. All plastic lid components, silicone gaskets, and straws are strictly BPA-free, lead-free, and fully compliant with FDA, EU LFGB, and California Prop 65 food-contact standards.
Standard mass production lead time is approximately 25 to 35 days post sample confirmation and deposit receipt. Expedited manufacturing schedules are available for repeat orders or simplified standard models.
We offer comprehensive branding technologies including laser etching/engraving, silk-screen printing, 3D digital UV printing, heat transfer printing, water transfer printing, matte/gloss powder coating, and electroplated metallic finishes.
Every product undergoes a 2-step thermal screening protocol: first after initial vacuum sealing via temperature sensors, and second after coating application. Our copper-plated vacuum barrier technology ensures minimal heat transfer through radiation and convection.
