View Product DetailsSituated in the strategic industrial heartland of Wuyi County, Zhejiang Province, China, Wuyi Dongyi Dailysupplies Co., Ltd. has established itself as an authoritative global manufacturer specializing in the research, development, custom engineering, and mass production of premium food-grade stainless steel drinkware.
Our expansive catalog includes double-walled vacuum insulation tumblers, sports bottles, travel mugs, cola flasks, outdoor jug containers, and specialized single-wall metal vessels. Powered by advanced automated production lines, laser welding technology, robotic polishing systems, and rigid quality inspection protocols, we empower global brands, importers, and retail distributors with certified high-performance drinkware built for international compliance.
Why CE Certification matters: Under European Directives (including General Product Safety Directive 2001/95/EC and EU Food Contact Regulation EC 1935/2004), sport water bottles must satisfy rigorous non-toxicity, structural integrity, thermal retention, and chemical safety standards.
| Technical Parameter | Standard Manufacturing Specification | Industry Advantage & Compliance Benefit |
|---|---|---|
| Inner Body Material | Austenitic 304 (18/8) Stainless Steel (0.4mm - 0.6mm thickness) | Zero metallic taste transfer, high corrosion resistance, zero toxic leaching. |
| Outer Body Material | Premium 304 or 201 Stainless Steel with Protective Coating | Impact-resistant outer shell with decorative durability and sweat-free grip. |
| Vacuum Technology | High-Vacuum Temperature Extraction (< 0.001 Pa vacuum level) | Guarantees 12 to 24 hours thermal insulation (Hot liquids > 65°C / Cold < 8°C). |
| Lid & Straw Components | 100% BPA-Free Polypropylene (PP) & Food-Grade Silicone Seals | Complete leakproof performance, non-toxic, heat resistant up to 120°C. |
| Surface Coating Tech | Automated Powder Coating, Electroplating, UV Sublimation, Matte Finish | Scratch-resistant finish, dishwasher-safe options, vivid customized branding. |

Manufacturing sport water bottles in Wuyi, Zhejiang gives global brand partners a formidable competitive edge. The integrated local industrial ecosystem drastically reduces production overhead, accelerates R&D turnaround, and maintains strict quality control.
Direct proximity to top-tier stainless steel mills ensures stable pricing and high-grade 304/316 raw materials. This eliminates supply chain friction, ensuring uninterrupted high-volume factory outputs.
Our facility utilizes laser vacuum sealing stations, robotic polishers, and automatic electrostatic powder lines. Automation yields high dimensional accuracy, uniform thermal insulation, and minimal defect rates.
Leveraging high production capacity and streamlined modular mold tooling allows Wuyi Dongyi to deliver highly competitive tier-1 factory pricing without compromising on material thickness or CE compliance standards.
The global sports water bottle market is undergoing a seismic shift driven by sustainability directives, eco-conscious consumer behavior, and demands for multi-functional ergonomic drinkware.
Global legislation—including the European Union's Single-Use Plastics Directive—has accelerated the corporate and consumer pivot toward reusable, infinitely recyclable 304 stainless steel vessels. Brands offering CE-certified durable steel bottles capture higher customer loyalty and fulfill green corporate governance (ESG) mandates.
Modern consumers demand versatile drinking experiences. Our product designs incorporate hybrid lid mechanisms allowing dual-purpose usage: a built-in folding straw for quick athletic sip access and a wide-mouth spout for rapid liquid replenishment or ice cube insertion.
From tactile powder coatings that provide enhanced grip during intense workouts to gradient ombre finishes and custom laser-etched corporate logos, high-end surface treatment is essential for consumer differentiation in competitive retail channels.
Demanding applications such as mountaineering, desert trekking, and cross-fit sports require deep-vacuum insulation capable of maintaining ice retention for up to 48 hours. Our advanced copper-lined vacuum chambers guarantee zero thermal transfer across exterior walls.
Wuyi Dongyi provides optimized macro solutions tailored for diverse global retail channels, corporate promotional distributors, outdoor gear brands, and private label importers.

Every sport water bottle manufactured at Wuyi Dongyi undergoes rigorous quality testing to ensure absolute compliance with CE, FDA, and European safety standards.
High-purity 304 food-grade stainless steel sheets are tested for chemical composition via spectrometer before hydraulic press deep drawing shapes the inner and outer bottle shells.
Inner and outer shells are laser-welded seamlessly. Bottles enter specialized vacuum furnaces where air is extracted under extreme heat to create high-efficiency vacuum insulation.
An interior copper coating is applied to reflect thermal radiation. 100% of bottles undergo automated temperature sensor testing; non-performing units are instantly rejected.
Bottles are electrolytically polished inside for a smooth, non-porous finish. Outer surfaces undergo automated spray painting, powder coating, or 3D water transfer printing.
Logos are applied using laser engraving, silkscreen, or heat transfer. Food-grade silicone gaskets and BPA-free lids are precision-assembled onto the bottle neck.
Randomized lot testing checks for leakproof seals, drop resistance, cross-hatch paint adhesion, and CE mark compliance before clean protective packaging and global shipping.
Everything you need to know about custom OEM/ODM manufacturing, CE certification compliance, MOQs, and global export shipping.
CE Certification confirms that our stainless steel water bottles comply with essential European health, safety, and environmental protection standards. This includes compliance with EU Food Contact Regulation (EC 1935/2004), ensuring zero toxic chemical leaching, zero heavy metals, and complete consumer safety for hot and cold beverages.
Yes, we specialize in comprehensive OEM and ODM solutions. We offer precise Pantone color matching for powder coatings and spray finishes, custom logo application (laser etching, silkscreen, 3D printing), personalized packaging boxes, and custom mold creation for unique lid and bottle silhouettes.
Type 304 stainless steel contains 18% chromium and 8% nickel, rendering it exceptionally resistant to rust, oxidation, and acidic corrosion from citrus juices or sports drinks. Unlike aluminum or lower-grade steels, 304 stainless steel requires no inner chemical lining and retains pure flavor without metallic transfer.
Standard MOQs start at 1,000 units per color/design for custom branding orders. Production lead times generally range between 20 to 35 days post sample approval and deposit confirmation, depending on design complexity and order volume.
By evacuating the air between the inner and outer stainless steel walls, heat conduction and convection are eliminated. Combined with an internal copper lining that reflects radiant heat, liquids stay hot for up to 12 hours and cold for up to 24 hours, preventing external condensation (sweating).
