Explore our primary line of high-performance 500ml and multi-capacity stainless steel drinkware, engineered for thermal efficiency, ergonomic handling, and retail readiness.
In the global commercial drinkware and personal hydration market, the 500ml (approx. 17 fluid ounces) water bottle represents the golden standard for ergonomic efficiency, commercial portability, and universal consumer adoption. Search intent analysis across international B2B platforms reveals that enterprise procurement teams, brand aggregators, retail distributors, and promotional gift suppliers continuously prioritize the 500ml volumetric profile over larger heavy-duty tumblers for daily urban commuting, fitness applications, and corporate branding initiatives.
As a leading wholesale 500ml water bottle supplier and custom manufacturer operating out of China's hardware capital region, Wuyi Dongyi Dailysupplies Co., Ltd bridges high-precision metallurgy with automated thermal insulation technology. Understanding user intent requires looking beyond mere vessel capacity; commercial buyers require comprehensive technical assurances regarding thermal retention rates, non-toxic material purity, international compliance certification, and reliable high-volume manufacturing throughput.
Wuyi Dongyi Dailysupplies Co., Ltd is located in the beautiful Wuyi county, Zhejiang Province, China. It is specialized in the production, research, and development of various food-grade stainless steel tumblers, mugs, bottles, cups, jugs, and containers. Our manufacturing catalog encompasses both advanced double-walled vacuum insulation constructions and single-wall structural designs engineered for diverse global markets.
We operate advanced production machinery and precise testing equipment managed under a strict quality control system (QMS). Our professional R&D team brings decades of combined engineering experience in stainless steel deep-drawing, vacuum degasification, surface coating technology, and ergonomic closure mechanisms. By enforcing rigorous raw material inspections and automated production protocols, we guarantee that every wholesale 500ml water vessel leaving our assembly lines complies with stringent international food safety standards.
Our automated manufacturing infrastructure in Zhejiang leverages state-of-the-art robotic welding and vacuum extraction to deliver uncompromising product reliability.
The hardware cluster in Wuyi County and neighboring Yongkang, Zhejiang Province, constitutes the world's most dense and sophisticated ecosystem for stainless steel drinkware manufacturing. Sourcing directly from Wuyi Dongyi provides critical competitive advantages for international brands.
We procure prime-grade Austenitic 304 (18/8) stainless steel directly from tier-one steel mills. High nickel and chromium content ensures superior corrosion resistance against acidic beverages, carbonated water, and isotonic sports drinks without metal leaching.
Our multi-stage continuous vacuum annealing ovens extract air at temperatures exceeding 1050°C. Internal copper lining option reflects infrared heat radiation, maximizing thermal insulation performance inside slim 500ml wall profiles.
Utilizing dust-free electrostatic powder coating, rubberized soft-touch sprays, and water-transfer printing lines, we achieve ultra-durable paint adhesion capable of surviving rigorous commercial dishwasher cycles and impact resistance tests.
We provide full-spectrum engineering support for international brands seeking customized 500ml water bottle tooling, private-label packaging, and unique lid mechanics.
