Explore our factory-direct insulated tumblers, coffee mugs, and specialized vacuum vessels crafted with food-grade 18/8 stainless steel.
In the rapidly transforming landscape of global retail, promotional merchandising, and functional drinkware, personalized thermal cups have evolved from simple utilitarian liquid containers into sophisticated lifestyle extensions and brand powerhouses. Global brands, corporate procurement officers, and e-commerce leaders no longer evaluate custom drinkware purely on price per unit. Today, the strategic value lies in metallurgical integrity, thermodynamic precision, custom aesthetic engineering, and total supply chain agility.
As a premier OEM Personalised Cups Manufacturer & Supplier based in the industrial manufacturing hub of Wuyi, Zhejiang, Wuyi Dongyi Dailysupplies Co., Ltd stands at the forefront of this industrial shift. Operating at the intersection of thermal science, advanced metalworking, and precise surface coating technologies, our facility engineers bespoke drinkware solutions engineered to exceed the rigorous standards of North American, European, and Asia-Pacific markets.
Located in Wuyi County, Zhejiang Province—the global epicenter of stainless steel vacuum flask production—Wuyi Dongyi Dailysupplies Co., Ltd operates a state-of-the-art manufacturing facility specialized in the complete research, development, custom design, and mass manufacturing of food-grade stainless steel drinkware.
Our catalog encompasses double-walled vacuum insulated tumblers, travel mugs, sleek sports bottles, wide-mouth cola flasks, mini Yerba Mate gourds, and high-capacity outdoor jugs. Through continuous capital investment in automated hydroforming, robotic vacuum extraction, laser engraving, and zero-emission powder coating lines, we deliver OEM/ODM partnerships built on precision engineering, absolute product safety, and verified thermal longevity.
Leveraging automated manufacturing, integrated raw material sourcing, and advanced quality validation to deliver unparalleled scalability for international OEM buyers.
Our production floor features multi-stage automatic deep-drawing hydraulic presses and robotic laser seam-welding systems. This eliminates mechanical wall inconsistencies, maintaining a uniform outer and inner wall thickness down to sub-millimeter tolerances for superior thermal efficiency and structural integrity against impact.
Thermal isolation is achieved through continuous high-vacuum evacuation ovens operating at temperatures exceeding 500°C. By evacuating inter-wall gas molecules down to 10^-4 Pa and inserting internal copper-coated radiative barrier foils, cold temperatures are sealed for 24+ hours and heat for 12+ hours.
We utilize premium SUS304 (18/8 stainless steel) certified free of lead, phthalates, and heavy metal contaminants. Electropolished interior surface treatments eliminate microscopic surface pits, inhibiting bacterial attachment and preventing flavor transfer across diverse liquid types.

We use premium food-grade 18/8 (SUS304) stainless steel for both internal and external walls on our premium vacuum tumblers. This alloy contains 18% chromium and 8% nickel, providing exceptional resistance against oxidation, acid corrosion from juices or coffee, and ensuring zero metallic taste transfer. For economy single-layer cups, 304 food-grade options are also available upon customer request.
Our standard MOQ for full OEM customization (custom Pantone color coating, laser etching, or customized lid branding) starts at 1,000 units per model/color. However, for initial brand sampling or market test campaigns using standard stock colors with custom laser-etched logos, we can support flexible lower volumes starting at 500 units.
Every vacuum vessel undergoes a 3-stage thermal validation process. After high-temperature vacuum evacuation in our continuous ovens, 100% of units are temperature-tested via infrared thermography sensors after 24 hours of resting. Any unit exhibiting wall temperature transfer is automatically rejected prior to surface coating and final packaging.
Yes. We offer complete ODM engineering services. Our in-house R&D team can design custom injection molds for multi-functional lids (e.g., flip-straw, magnetic sliders, dual-sip openings) and soft-grip handles tailored to your precise ergonomic requirements and brand aesthetic.
Absolutely. All materials—including stainless steel bodies, BPA-free AS/Tritan lids, and food-grade silicone gaskets—are tested and certified by independent testing agencies (SGS, Intertek) to comply with US FDA standards, European LFGB regulations, and California Proposition 65 lead/cadmium limits.
Digital 3D proofs are delivered within 24–48 hours. Physical pre-production samples with custom logo/coating take approximately 7–10 business days. Standard mass production turnaround is 25–35 days upon sample approval and deposit receipt, depending on seasonal volume demands.
Electrostatic powder coating provides the highest durability and scratch resistance compared to traditional spray painting. It creates a textured, tactile finish that is resistant to chipping, sweat-proof, and safe for commercial dishwasher cycles.
