View Technical SpecsWuyi Dongyi Dailysupplies Co., Ltd, situated in the industrial hardware hub of Wuyi County, Zhejiang Province, China, stands at the forefront of modern thermodynamic drinkware manufacturing. Our operational facility integrates advanced metallurgy, automated deep-drawing processing, high-vacuum evacuation systems, and rigorous compliance testing to service multinational brands, global importers, and e-commerce enterprises.
As a premier ODM (Original Design Manufacturer) and OEM supplier, our engineering matrix encompasses full-spectrum research, physical prototyping, ergonomic lid integration, and eco-friendly surface finishing. Whether delivering standard 20oz insulated coffee tumblers, 40oz heavy-duty hydrators, or bespoke ergonomic travel mugs, our processes prioritize structural integrity, zero-leak sealability, and thermal retention exceeding international industry benchmarks.
In the modern B2B beverage container landscape, commercial buyers encounter multifaceted challenges—ranging from vacuum failure rates and surface coating degradation to regulatory hurdles regarding heavy metal migration. Dongyi Dailysupplies resolves these enterprise pain points through state-of-the-art material selection and physical vacuum engineering.
We utilize authentic 18/8 (SUS304) austenitic stainless steel for both inner and outer vessel walls. This high-nickel/chromium formulation provides exceptional corrosion resistance against acidic beverages such as cold-brew coffee, citrus infusions, and carbonated liquids.
Our automated vacuum evacuation chambers operate at temperatures exceeding 500°C to strip air molecules between double walls down to 10^-3 Pa, creating an absolute thermal barrier against conduction and convection heat transfer.
To minimize radiant thermal loss, the outer side of the inner stainless steel wall receives an electroplated copper coating. This reflective barrier bounces thermal radiation back into the liquid core, enhancing heat retention by up to 30% over standard vacuum designs.

Operating out of Wuyi, Zhejiang—the nerve center of global hardware and vacuum flask production—Wuyi Dongyi Dailysupplies Co., Ltd leverages an end-to-end industrial cluster. This geographic and operational positioning provides our international wholesale partners with distinct strategic advantages in lead times, material sourcing stability, and cost structure.
Our facility features automated hydraulic pressing and laser welding units that transform solid stainless steel coils into flawless inner and outer liners. This precise shaping maintains consistent wall thickness (0.4mm–0.6mm), eliminating structural micro-fractures that lead to vacuum loss over prolonged usage.
Equipped with zero-emission electrostatic powder coating lines, we deliver scratch-resistant, tactile surface treatments in customized Pantone shades. Our multi-axis robotic arms guarantee 360-degree uniformity without dripping or paint pooling around lip seals.
Every individual production batch undergoes rigorous Quality Control protocols: 100% temperature test pass-through in automated infrared sensors, seal tightness water-immersion testing under high pressure, and drop-impact resistance sampling.
From established retail brands in North America and Europe to fast-growing beverage startups in South America, the Middle East, and Southeast Asia, client market requirements vary greatly. Our company obeys the fundamental operational principles: Quality First, Service First. We bridge the gap between abstract design concepts and mass production.
We provide precision laser etching, silkscreen printing, heat transfer printing, 3D UV digital printing, and embossed logo application. Elevate your brand identity with intricate metallic logos or vibrant full-wrap artwork.
The drinking interface defines user satisfaction. We develop multi-functional lid systems—including dual-sip/straw mechanisms, magnetic slider lids, push-button locking flip caps, and integrated silicone boot attachments.
For large-volume vessels (such as 30oz and 40oz tumblers), our ergonomic handles are molded with reinforced internal pins, soft-touch silicone grips, and car-cup holder compatible base diameters.
As consumer preferences shift toward sustainable lifestyle choices and smart technology integration, our R&D team is actively commercializing next-generation thermal vessel technologies.
Integration of low-power LED touch sensors into lid architectures to provide real-time liquid temperature readouts, preventing scalding and optimizing specialty coffee brewing windows.
Pioneering the use of 90% Post-Consumer Recycled (PCR) 304 Stainless Steel, reducing carbon footprint by up to 60% per unit manufactured to satisfy strict European corporate sustainability mandates.
Deploying ultra-thin, non-porous ceramic interior coatings over stainless steel walls to preserve 100% pure flavor integrity, completely eliminating metallic residual taste in acidic espresso drinks.
Navigating international trade barriers requires transparent certification and localized market compliance. Wuyi Dongyi Dailysupplies Co., Ltd maintains rigorous global compliance standards to ensure seamless customs clearance and retail placement worldwide.
All materials used in our cups—from stainless steel walls to silicone gasket rings and polymer lids—are tested and certified under US FDA 21 CFR, EU LFGB, and DGCCRF standards. Heavy metal leaching (Lead, Cadmium) is strictly non-detectable.
Our manufacturing facilities adhere to international social responsibility frameworks, holding BSCI (Business Social Compliance Initiative) and SEDEX certifications to support ethical sourcing requirements of global retailers.
We provide complete freight management services including FOB, CIF, DDP (Delivered Duty Paid), offering hassle-free customs clearance, warehousing, and door-to-door delivery across North America, Europe, and the Middle East.

A: 18/8 (SUS304) stainless steel contains 18% chromium and 8% nickel, providing superior resistance against corrosion, chemical oxidation, and acid leaching from acidic beverages like coffee and fruit juices. Grade 201 steel, while cheaper, contains higher manganese and lower nickel, making it prone to internal rusting and metallic taste migration over time. Wuyi Dongyi exclusively utilizes food-grade SUS304/SUS316 for all beverage contact surfaces.
A: Our standard MOQ for stock color models with custom laser-etched or silkscreened logos is 500 to 1,000 units. For fully customized Pantone spray coatings, unique powder finishes, or customized packaging, the MOQ is generally 2,000 to 3,000 units. Custom volumetric vessel mold developments require an MOQ based on tooling amortization metrics.
A: Thanks to our double-wall vacuum evacuation processing and copper-plated internal reflection shielding, our tumblers maintain hot temperatures (>60°C) for 6 to 12 hours and keep liquids cold (<8°C) with ice retention for 24 to 36 hours under standard ambient laboratory test conditions (EN 12546-1 standard).
A: Absolutely. All polymer components (including Tritan, AS, and PP lid lids) and food-grade silicone sealing rings are 100% BPA-free, BPS-free, and Phthalate-free. We provide certified laboratory test reports covering US FDA 21 CFR 177.1520, EU LFGB German Food Code, and EU Reach regulations.
A: Custom graphic artwork proofing and laser/print samples take approximately 5 to 7 business days. Custom mold creation for brand-new bottle shapes requires 25 to 35 days. Once pre-production samples are approved, full-scale mass production lead time averages 30 to 40 days, depending on batch order size and finishing complexity.
A: Every individual cup passes through a two-stage automated thermal inspection line. After vacuum evacuation, cups are charged with heat and scanned via infrared temperature sensors to detect thermal leaks. Any unit exhibiting outer shell temperature rise is automatically rejected. Additional drop tests and coating adhesion cross-hatch testing are performed on every production lot.
