Explore our core catalog of enterprise-grade stainless steel drinkware, engineered for high-performance thermal retention, structural durability, and custom brand alignment.
The global reusable metal bottle market is undergoing a seismic paradigm shift. Driven by worldwide legislative mandates banning single-use plastics, expanding consumer health awareness, and aggressive ESG (Environmental, Social, and Governance) commitments by Fortune 500 enterprises, stainless steel vacuum insulated bottles have transitioned from niche outdoor commodities to indispensable lifestyle equipment and corporate identity tools.
Market intelligence projects the worldwide insulated drinkware industry to surpass USD 11.8 Billion by 2030, registering a robust CAGR of 6.8%. Crucial drivers shaping current corporate procurement strategies include:
Modern buyers demand more than simple fluid containment. End-users expect thermal efficiency capable of retaining ice for 24+ hours or keeping hot liquids above 65°C for 12 hours. Ergonomic handles, sip-thru straw lids, powder-coated scratch-resistant surfaces, and vibrant Pantone color schemes are now standard enterprise specifications.
Corporations and retail brands are actively liquidating plastic product lines to align with carbon-neutral targets. Stainless steel bottles provide a circular lifecycle—100% recyclable, zero BPA, phthalate-free, and designed for decades of repetitive operational usage.
E-commerce ecosystems (Amazon FBA, Shopify storefronts, corporate promotional channels) require agile ODM partners capable of low-MOQ prototyping, high-volume production scalability, and custom retail-ready packaging integration.
At the core of high-performance manufacturing is strict adherence to metallurgical purity and thermodynamic engineering. As an established ODM/OEM factory based in Wuyi, Zhejiang, Wuyi Dongyi Dailysupplies Co., Ltd leverages specialized manufacturing protocols to guarantee long-term thermal retention and chemical safety.
Not all metal drinkware is constructed equal. Understanding raw material properties is critical for global brand procurement managers seeking compliance with FDA, LFGB, and CE regulatory standards:
| Material Grade | Composition (Cr / Ni / Mo) | Corrosion Resistance | Optimal Application Scenario | Compliance Standards |
|---|---|---|---|---|
| SUS304 (18/8) | 18% Chromium, 8% Nickel | High resistance to oxidation, water, and acidic beverages. | Standard Insulated Tumblers, Sports Flasks, Coffee Mugs | FDA Food Grade, LFGB, CE certified |
| SUS316 (18/10) | 18% Chromium, 10% Nickel, 2% Molybdenum | Superior resistance to chlorides, saline liquids, and harsh chemicals. | Medical-grade flasks, extreme environment gear, specialized baby bottles | Pharma/Medical grade, ISO 10993, REACH compliant |
| Single-Wall SS | 18/8 Stainless Steel (Non-vacuum) | Standard mechanical resilience; ultra-lightweight. | Ultra-light trekking bottles, single-wall ice cups | Food safe, direct contact certified |
Our double-walled vacuum vessels utilize a specialized high-vacuum evacuation process operating at temperatures exceeding 500°C. By evacuating the air trapped between the inner and outer stainless steel walls, heat transfer via conduction and convection is virtually eliminated. Furthermore, we apply an internal electrolytic copper lining reflection layer on the vacuum-facing side of the inner wall, which reflects thermal radiation back into the liquid, boosting heat retention efficiency by up to 30%.
Situated in the industrial heartland of Wuyi County, Zhejiang Province, Wuyi Dongyi Dailysupplies Co., Ltd embodies the modern "Industry 4.0" transformation of Chinese manufacturing. By merging automated robotics with rigorous QA/QC inspection matrices, we provide corporate importers with unrivaled supply chain reliability.
High-precision hydraulic presses form seamless inner liners and outer shells with zero micro-fractures, ensuring uniform wall thickness and structural integrity under physical impact.
Automated fiber-laser welding arms join bottle necks and bottoms with pinpoint precision, producing virtually invisible seams that prevent structural leaks and maintain vacuum seal integrity over long time horizons.
100% of manufactured units undergo automated thermal sensor testing before surface finishing. Uninsulated or defective items are automatically purged from the assembly line by computerized optical sorting.
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.

Our products are deployed across worldwide markets, tailored specifically to regional user preferences, environmental conditions, and cultural habits:
Driven by lifestyle wellness trends, demand centers on large-capacity 40oz and 30oz insulated tumblers with ergonomic handles and vehicle cupholder-compatible tapered bases. Heavy-duty powder coating is essential for daily commuting and gym use.
European markets prioritize streamlined 500ml–750ml sports flasks and skinny tumblers. High emphasis is placed on LFGB compliance, zero-plastic contact lids, recyclable packaging, and sleek Scandinavian aesthetic finishes.
Extreme ambient temperatures demand maximum insulation capabilities for both freezing cold water and hot tea/coffee. Large 64oz growlers and vacuum handle cups with high structural wall thickness dominate regional bulk sourcing orders.
Find quick technical answers regarding our manufacturing processes, customization parameters, quality compliance, and wholesale ordering policies.
Our standard factory MOQ is typically 1,000 units per color/design for custom surface coatings and logos. For existing stock models requiring minimal custom branding, flexible trial orders of 500 units can be accommodated.
Yes. All our products are engineered using premium food-grade 304 (18/8) stainless steel. Our components are 100% BPA-free, lead-free, and fully compliant with US FDA, European LFGB, and CE international food safety regulations.
We enforce a 3-stage thermal testing regimen. After vacuum sealing, all bottles pass through an automated thermal infrared chamber to detect temperature dissipation. Units that fail to meet strict heat insulation standards are automatically discarded.
Absolutely. Our dedicated in-house R&D engineering team offers full ODM services. We produce custom steel tooling and plastic injection molds based on your 3D CAD files or step drawings within 20-30 days.
Mass production generally requires 30 to 35 days following sample confirmation and deposit approval. Expedited production schedules can be arranged for high-volume enterprise contracts.
Powder coating provides the highest durability and scratch resistance compared to standard liquid spray painting. It creates a textured, slip-resistant surface that withstands dishwasher environments and rough outdoor exposure.
