Explore our premium grade double-walled stainless steel insulated drinkware engineered for global enterprise private labeling.
Elevating global drinkware brands with verified manufacturing expertise, state-of-the-art thermal technology, and unmatched OEM reliability.
Strategic Sourcing Note: Sourcing high-performance coffee cups requires balancing thermal dynamics, ergonomic functionality, chemical safety compliance (BPA/LFGB), and structural durability. As a tier-1 OEM cups coffee supplier, we bridge advanced metallurgy with automated manufacturing to guarantee zero-defect performance for global enterprise buyers.
Wuyi Dongyi Dailysupplies Co., Ltd. is located in Wuyi County, Zhejiang Province, China—a world-renowned hub for high-end stainless steel hardware and vacuum flask manufacturing. We specialize in the research, development, engineering, and large-scale manufacturing of premium food-grade stainless steel drinkware. Our wide product spectrum encompasses double-walled vacuum insulation tumblers, coffee mugs, hydration bottles, sport flasks, travel jugs, and specialized insulated coffee containers designed for international retail chains, private labels, and promotional merchandise brands.
Our state-of-the-art facility integrates advanced automatic machinery, robotic laser welding lines, high-vacuum evacuation systems, and multi-stage quality testing equipment. Operating under a rigorous ISO-aligned quality control protocol, our highly experienced R&D team continuously delivers market-defining designs, robust structural engineering, and customized aesthetic coatings. Whether executing high-volume OEM projects or agile ODM customizations, Wuyi Dongyi stands as a trusted manufacturing backbone for enterprise importers across North America, Europe, South America, the Middle East, and Southeast Asia.
From our inception, Wuyi Dongyi has consistently operated under two core tenets: "Quality First, Service First." We believe that market leadership is built upon uncompromised material integrity and transparent client collaboration. By utilizing premium 18/8 (SUS304) and medical-grade 316 stainless steel, we ensure that every coffee cup and tumbler leaving our assembly line possesses superior corrosion resistance, flavor neutrality, and long-lasting thermal retention capabilities.
How cutting-edge thermal insulation science and material technology are reshaping the modern OEM coffee cup market.
Implementation of ultra-high vacuum evacuation (10^-4 Pa) backed by internal copper plating. This reduces thermal radiation loss to near zero, maintaining coffee temperature (>65°C) for up to 12 hours and cold brew (<5°C) for over 24 hours.
To eliminate metallic lingering tastes in premium specialty coffee, our roadmap integrates plasma-deposited ceramic coatings and mirror-smooth electropolished internal walls, ensuring pure flavor integrity and easy cleaning.
Multi-functional food-grade Tritan lid systems equipped with magnetic slide locks, pressure-release valves, silicone gasket dynamic seals, and integrated real-time digital temperature display modules for premium consumer appeal.
Modern consumers demand tactile elegance alongside physical durability. Our production lines feature eco-friendly, zero-VOC electrostatic powder coating systems, gradient sublimation printing, 3D laser engraving, and soft-touch tactile rubberized finishes. These surface technologies resist high-friction dishwasher cycles while retaining vibrant brand aesthetics.
Combining robotic automation, lean manufacturing, and regional supply chain integration in Zhejiang to maximize speed-to-market.
Operating from Wuyi County, Zhejiang, our production facility benefits from an ultra-dense industrial cluster. From raw stainless steel coil sourcing to precision tooling, silicone gasket molding, packaging design, and export logistics, every node of the supply chain exists within a 50-kilometer radius. This geographic advantage translates into unmatched cost efficiency, rapid prototyping turnaround, and supply chain resilience against global disruptions.
Ensures seamless, hermetically sealed inner and outer stainless steel shells, eliminating structural weak points and preventing vacuum degradation over long-term usage.
Fully automated multi-station vacuum furnace lines monitor pressure parameters in real-time, enforcing stringent temperature-retention standards across 100% of manufactured units.
Every single coffee mug undergoes dynamic infrared heat sensor screening post-evacuation to immediately detect and reject units failing thermal performance metrics.
Our modular production lines accommodate rapid switching between standard 20oz/30oz/40oz tumblers and custom bespoke shapes, supporting diverse client product portfolios.
Addressing the specific operational and commercial needs of coffee franchises, retail brands, corporate buyers, and e-commerce distributors.
For international coffee houses, custom-designed reusable tumblers drive customer loyalty and support sustainability mandates. We offer custom pantone color matching, specialized barista cup sizes (8oz, 12oz, 16oz, 20oz), car-cup-holder compatible base geometries, and spill-resistant lid mechanisms tailored for on-the-go coffee consumers.
E-commerce brands require high visual differentiation, optimized drop-test protective packaging, and fast seasonal inventory turnover. We provide comprehensive OEM service packages including custom color boxes, barcode stickering, ISTA-6 packaging compliance, and flexible MOQs to streamline product launches.
Corporate procurement demands premium sensory appeal and robust brand representation. Our laser-etched stainless steel mugs, egg-shaped wine/coffee tumblers, and matte-finished travel flasks provide elegant merchandise solutions that elevate corporate identity during events, trade shows, and executive gift campaigns.
Rugged outdoor environments necessitate impact-resistant drinkware. We manufacture heavy-duty 32oz, 40oz, and 48oz insulated hydration flasks featuring powder-coated exteriors, reinforced stainless steel handles, leakproof straw caps, and extreme cold-retention capabilities for wilderness exploration.
Ensuring frictionless international trade through rigorous product testing, eco-conscious manufacturing, and regional import compliance.

Expert answers addressing standard operational, technical, and regulatory procurement queries.
We primarily utilize premium food-grade 18/8 (SUS304) stainless steel for both the inner liner and outer shell of our insulated coffee cups. For specialized medical, infant, or high-acid beverage applications, we offer SUS316 surgical-grade stainless steel inner liners upon request. All materials are certified 100% rust-proof, non-toxic, and free from heavy metals.
Vacuum insulation integrity is maintained through our high-temperature automated vacuum furnace evacuation process combined with internal wall copper coating. The copper lining reflects thermal radiation back into the container, while the evacuation chamber creates an ultra-high vacuum environment (10^-4 Pa). 100% of finished products undergo 2-stage infrared heat detection testing prior to final assembly.
Our standard production MOQ ranges from 1,000 to 3,000 units per style/color, depending on custom surface treatment requirements (e.g., custom Pantone color matching, powder coating, or full 3D wrap printing). Sample development takes 7 to 12 days, while full production turnaround is typically completed within 30 to 35 days post sample confirmation.
We offer comprehensive aesthetic surface customizations including electrostatic powder coating, durable spray painting, gradient rubberized matte finish, mirror electroplating, heat-transfer pattern printing, water-fade film wrap, 3D UV digital printing, precision laser engraving, and custom debossed/embossed metal logo stamping.
