Explore our top-tier vacuum insulated tumblers, sports bottles, and custom drinkware engineered for global brands and enterprise buyers.
A premier OEM/ODM industrial manufacturer specializing in advanced thermodynamic drinkware engineering and precision thermal containment systems.
Located in the renowned hardware industrial hub of Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd stands as an industry-leading OEM and ODM manufacturer dedicated to the research, development, structural engineering, and automated production of high-grade food-standard stainless steel tumblers, personalized mugs, vacuum bottles, thermal cups, outdoor sports flasks, and insulated beverage containers.
Our core manufacturing matrix encompasses both double-walled vacuum insulation constructions and single-wall precision steel vessels. Operating under strict adherence to international standard quality management systems, our facility incorporates high-precision automated laser welding, state-of-the-art vacuum extraction chambers, multi-axis robotic powder coating lines, and rigorous internal testing labs.
Since our inception, Dongyi has operated under the steadfast operational principles: "Quality First, Service First." Through persistent technical innovation and strict compliance with global food contact safety parameters (FDA, LFGB, REACH, Prop 65), we have built enduring manufacturing partnerships across North America, Europe, South America, the Middle East, and Southeast Asia.
Leveraging Zhejiang's advanced industrial hardware cluster to deliver ultra-reliable production speed, cost optimization, and technical precision.
Our facility utilizes automated multi-stage vacuum extraction units operating at $10^{-3}$ Pa vacuum pressure levels. Internal copper plating coating layers are electro-deposited onto the inner steel vessel to reflect thermal radiation, guaranteeing 24-hour ice retention and 12-hour thermal heat preservation.
We enforce strict incoming raw material spectral analysis. All personalized mugs, tumblers, and flasks utilize certified premium food-grade 18/8 (SUS304) stainless steel or medical-grade SUS316, preventing oxidation, chemical leaching, heavy metal migration, and flavor transfer.
From robotic electrostatic powder coating to full-bleed 3D sublimation transfer, UV digital printing, water-transfer marbling, and precision laser engraving. Our surface coating adhesion passes 100% cross-hatch tape testing (ASTM D3359) for high dishwasher resistance.
Deep integration within the Wuyi-Yiwu-Ningbo industrial corridor reduces component sourcing lead times by 40%. Direct access to Ningbo and Shanghai ports enables flexible freight logistics, rapid sample iteration (3-5 days), and reliable volume production scaling.
Tailored OEM/ODM manufacturing protocols engineered to satisfy high-volume distributors, Amazon sellers, and luxury brand requirements.
Our engineering department delivers full CAD/3D modeling support. We custom-tool proprietary vessel shapes, ergonomic handles, weighted silicone bases, and multi-functional sealing lids (sip, straw, and leak-proof flip mechanisms).
Match any Pantone (PMS) color with gradient spray, rubberized soft-touch tactile finishes, metallic electroplating, glitter finishes, or classic durable powder coat finishes tailored for outdoor ruggedness.
Full commercial packaging support including FSC-certified recyclable color boxes, die-cut foam inserts, custom barcoding/FBA labeling, laser engraving logos on bottom caps, and custom sleeve wrapping.
Supplying tailored drinkware solutions across diverse global sectors, driving market share for retail brands and promotional conglomerates.
We assist direct-to-consumer (D2C) brands with low MOQ sample runs, trendy product designs (e.g., 40oz handle tumblers, egg-shaped wine tumblers, skinny tumblers), and drop-test certified e-commerce protective packaging.
High-precision laser-etched customized corporate logo mugs for fortune 500 promotional campaigns, staff onboarding gift kits, and sports event sponsors, guaranteeing brand consistency and premium outlooking.
Engineered high-capacity (32oz, 48oz, 64oz) heavy-duty vacuum flasks equipped with paracord handles, leak-proof straw lids, and ultra-durable powder coating built to withstand harsh outdoor wilderness environments.
Pioneering the next generation of smart thermal drinkware, sustainable material science, and circular manufacturing processes.
Integrating real-time digital OLED temperature lid displays and embedded 280nm UV-C LED water purification modules within bottle caps to eliminate 99.99% of bio-contaminants for global travelers.
Pioneering the transition toward Post-Consumer Recycled (PCR) stainless steel. Reducing carbon footprint by over 60% while maintaining identical structural tensile strength and anti-corrosion properties.
Utilizing advanced internal wall spin-thinning processes to reduce inner vessel thickness down to 0.12mm, achieving ultra-lightweight thermal mugs ideal for minimalist hiking and everyday carry without compromising thermal insulation efficiency.
Ensuring full regulatory compliance across North America, Europe, and Asia-Pacific import regulatory frameworks.
All raw materials—including stainless steel, food-grade silicone gaskets, and BPA-free Tritan/PP plastics—are fully tested by third-party labs (SGS, TUV, Intertek) to meet FDA 21 CFR, EU LFGB, and DGCCRF compliance.
Dongyi operates under strict workplace safety, environmental ethics, and fair labor practices, maintaining BSCI (Business Social Compliance Initiative) and ISO 9001:2015 Quality Management System certifications.
