Explore our CE-compliant, vacuum-insulated stainless steel hydration vessels engineered for global B2B procurement, private label distribution, and large-scale retail supply.
Wuyi Dongyi Dailysupplies Co., Ltd is located in the beautiful Wuyi county, Zhejiang Province, China. It is specialized in production, research and development of kinds of food grade stainless steel tumblers, mugs, bottles, cups, jugs and containers, etc., both double-walled vacuum insulation construction and single wall construction are included. We have advanced production machines and testing equipments, strict quality controlling system, and professional team of research & development with much experience in this field.
Operating as a trusted premier CE Certification Water And Bottle Supplier & Suppliers, Dongyi integrates high-grade material selection, precision metallurgy, thermal thermodynamic vacuum engineering, and customized ergonomic design. Our industrial campus houses fully automated production lines capable of executing high-precision hydraulic expansion, automated laser welding, high-vacuum degassing, and automated electrostatic powder coating.
Understanding the physics of thermal insulation, zero-leakage seals, and chemical inertness in B2B drinkware procurement.
Our primary raw material utilizes premium 18/8 austenitic stainless steel, containing 18% Chromium and 8% Nickel. Chromium forms a self-healing, microscopic chromium-oxide passive film ($Cr_2O_3$) on the surface, preventing oxidation and acid-based corrosion. Nickel provides deep ductility and structural integrity under dynamic temperature fluctuations.
The double-wall interstitial space is evacuated at temperatures exceeding 1050°C to achieve a deep vacuum state of $10^{-4}\text{ Pa}$. Internal getters are incorporated into the vacuum chamber to absorb residual gas molecules (oxygen, hydrogen, nitrogen) over the product's lifetime, completely eliminating heat transfer via conduction and convection.
To neutralize thermal radiation losses, the outer surface of the inner stainless steel wall is electro-plated with an ultra-thin pure copper layer ($Cu$). This reflective barrier acts as a thermal mirror, redirecting infrared heat radiation back into the contained liquid and extending cold/hot holding capability up to 24 hours.
Securing genuine CE certification and meeting European Single Market directives requires rigorous quality control and strict adherence to non-toxic, food-safe manufacturing protocols. As a specialized CE Certification Water And Bottle Supplier, Wuyi Dongyi ensures every production batch conforms to international legal directives:
Ensures that materials coming into contact with food or beverages do not transfer their constituents into food in quantities that could endanger human health or bring about an unacceptable change in the composition of the food.
Comprehensive organoleptic testing (flavour and odor neutralness), heavy metal migration screening (Lead, Cadmium, Chromium, Nickel), and strict BPA/BPS-free verification for silicone gaskets and PP lids.
Rigorous audit of 230+ Substances of Very High Concern. All paint coatings, powder finishes, and plastic accessories comply with strict phthalate and polycyclic aromatic hydrocarbon (PAH) limits.
Leveraging Zhejiang's premier hardware industrial cluster to deliver uncompromised quality control, scalability, and rapid production cycles.
Utilizing CNC multi-station hydraulic expanders and automated spin-forming machinery, we achieve uniform wall thickness down to 0.4mm for ultra-lightweight designs without sacrificing tensile strength or vacuum integrity.
Robotic fiber laser welding guarantees hermetically sealed seams along the bottle rim and bottom joint. Lead-free glass bead vacuum sealing technology replaces outdated lead-seal processes, meeting eco-friendly standards.
Equipped with dust-free electrostatic spray coating, durable powder coating, gradient water transfer, silk-screen printing, and 3D UV digital printing to deliver bespoke surface textures, high durability, and brand recognition.
From outdoor performance gear to luxury corporate gifting, Wuyi Dongyi adapts its OEM/ODM production lines to meet diverse vertical market demands.
Targeted solutions including 32oz, 40oz, and 64oz wide-mouth vacuum flasks equipped with rugged powder coatings, paracord handles, leak-proof straw lids, and dual-function spout caps built for rugged mountain environments.
Designed for Amazon FBA, Shopify, and global supermarket chains. Focus on viral product styles like the 40oz handle quencher tumbler, skinny tumblers, and egg-shaped wine cups with customizable Pantone matching.
Premium 20oz coffee tumblers, yerba mate gourds, and sleek cola-shaped bottles ideal for fortune 500 corporate gift campaigns, luxury hotel amenities, and promotional merchandise projects.
Pioneering next-generation thermal technologies, smart hydration sensors, and zero-carbon circular economy initiatives.
Integrating up to 90% Post-Consumer Recycled (PCR) 304 stainless steel in vessel bodies, reducing carbon footprint by 65% while maintaining strict metallurgy standards.
Embedded OLED digital temperature displays, UV-C LED self-sterilization caps, and Bluetooth hydration tracking apps integrated seamlessly into OEM bottle caps.
Sub-micron ceramic spray coating applied inside the stainless steel interior wall, ensuring 100% resistance against acidic fruit juices, coffee oil build-up, and metallic taste transfer.
Next-gen rotary spinning techniques reducing overall vessel weight by 30% without diminishing structural rigidity or vacuum thermal retention times.

Expert answers to common engineering, certification, and procurement queries regarding CE certified water bottles and tumblers.
While CE marking is traditionally associated with electronics, drinkware sold within the European Single Market must meet mandatory safety standards under the General Product Safety Directive (GPSD) and specific EU food contact regulations (EC No. 1935/2004). CE certification validates that the bottle materials do not leach harmful heavy metals (such as Lead, Cadmium, or Nickel), that thermal insulation meets EN 12546-1 standards, and that pressure relief valves or lids pose no choking or explosion hazards under hot liquid expansion.
SUS304 (18/8 stainless steel) contains 18% Chromium and 8% Nickel, offering exceptional corrosion resistance and mechanical durability suitable for water, coffee, and tea. SUS316 (18/10 stainless steel) adds 2-3% Molybdenum, providing superior resistance to chloride pitting and high salinity environments. SUS316 is ideal for specialized medical, infant, or high-acid beverage containers, though SUS304 remains the global cost-effective benchmark for consumer hydration products.
We implement 100% 3-stage thermal temperature testing during manufacturing. After the high-temperature vacuum degassing furnace phase ($10^{-4}\text{ Pa}$), vessels undergo infrared thermal imaging: first immediately after sealing, second after high-pressure air blowing, and third prior to final coating. Any vessel exhibiting thermal leakage or wall heat transfer is automatically rejected by robotic sensors.
We offer full-spectrum custom execution including Pantone-matched powder coating, matte/gloss spray finishing, electroplating, water-transfer camouflage patterns, 3D UV digital texture printing, laser etching, silicone band embossing, custom molded lid functions (magnetic closure, flip spout, straw tops), and bespoke eco-friendly packaging boxes.
Standard OEM production MOQs start at 1,000 units per color/style for customized powder coatings and logos. For stocked raw bottle blanks, lower MOQs can be negotiated. Sample proofing typically takes 7-10 days, while mass production lead time is approximately 25-35 days following sample approval and deposit confirmation.
Yes. All plastic accessories (PP caps, Tritan straws, ABS handles) and food-grade silicone sealing rings are 100% BPA, BPS, and Phthalate-free. Every component undergoes rigorous third-party testing (SGS, TUV, Intertek) to ensure full compliance with FDA 21 CFR and EU REACH regulations.
