Explore our flagship series of vacuum-insulated tumblers, coffee mugs, and outdoor flasks engineered to meet rigorous international food-grade standards and precise client customizations.
The global reusable drinkware and mug market is experiencing a profound paradigm shift driven by strict international environmental mandates, such as the EU Single-Use Plastics Directive, and escalating consumer demand for personal wellness, thermal performance, and premium aesthetics. As brands transition from off-the-shelf catalog sourcing to sophisticated Original Design Manufacturing (ODM), technical precision, material integrity, and regulatory compliance have become the core pillars of competitive advantage.
Wuyi Dongyi Dailysupplies Co., Ltd is situated in the strategic hardware industrial hub of Wuyi County, Zhejiang Province, China. We are an enterprise specializing in the research, engineering development, precision tooling, and scalable mass manufacturing of food-grade stainless steel tumblers, insulated mugs, sports water bottles, travel cups, and specialized thermal containers.
Operating under strict quality control management systems, our facility incorporates both double-walled vacuum insulation construction and single-wall stainless steel production lines. Our multidisciplinary R&D team works side-by-side with global partners to transform complex engineering concepts into market-ready, high-performing drinkware lines.
Creating market-leading thermal drinkware requires an intimate knowledge of heat transfer mechanisms: conduction, convection, and radiation. Our manufacturing pipeline integrates high-precision engineering protocols to eliminate heat gain or loss.
Our vacuum chambers extract air down to high-grade vacuum levels between inner and outer steel walls. By using active zirconium getter materials inside the vacuum cavity, residual gas molecules are trapped, ensuring thermal stability for over 8–10 years of daily use.
To eliminate thermal radiation losses, the exterior wall of the inner stainless steel container is coated with a microscopic layer of electrolytic copper. This acts as a radiant heat mirror, reflecting thermal energy back into hot liquids or keeping ambient infrared heat out of cold beverages.
We provide diverse surface coating options: durable powder coating (sweat-free grip and impact resistance), 3D UV printing for complex tactile graphics, electroplated metallic gloss, and inner ceramic lining to protect acidic beverages (like coffee and citrus) from metallic off-tasting.
Drinkware preferences vary significantly across different geographies, demographic segments, and daily routines. Our ODM engineering capability allows custom tailor-fitting of product forms to regional user behaviors.
Demand in North America centers around large-volume hydration (30oz and 40oz insulated tumblers with ergonomic handles). Key requirements include slim base contours engineered to fit standard automotive cup holders, spill-proof dual-function sip/straw lids, and vibrant seasonal powder coating shades.
European consumers prioritize minimalist design, zero-plastic contact, and strict environmental compliance (LFGB & EU 10/2011). 12oz to 20oz double-wall travel mugs with leak-proof flip-lids for public transit commuting and espresso-machine-compatible heights dominate this regional sector.
Latin American markets demand dedicated thermal Yerba Mate gourds (8oz mini insulated cups) featuring wide openings and double-wall temperature maintenance. East Asian markets favor ultra-lightweight vacuum flasks, slim 20oz skinny tumblers, and egg-shaped wine/tea tumblers.
Located in Zhejiang Province—the global hub of hardware and stainless steel bottle manufacturing—Wuyi Dongyi Dailysupplies leverages an unparalleled industrial ecosystem. This cluster proximity grants immediate access to raw materials, tooling experts, precision mold makers, and automated packaging suppliers.
