Explore our OEM/ODM manufacturing range built with food-grade 304 stainless steel, dual-wall vacuum isolation, and customized ergonomic lids.
Situated in Wuyi County, Zhejiang Province—the global hub of hardware and stainless steel drinkware manufacturing—Wuyi Dongyi Dailysupplies Co., Ltd stands as a premier manufacturer, researcher, and developer of food-grade stainless steel tumblers, colourful mugs, vacuum bottles, outdoor hydro flasks, and insulated beverage containers.
Our industrial facility is equipped with automated deep-drawing hydraulic presses, high-precision vacuum pumping ovens, robotic copper-plating lines, and zero-defect laser welding systems. By integrating raw material metallurgical testing with strict inline quality controls, we engineer both double-walled vacuum insulation constructions and single-wall functional containers engineered to withstand global distribution demands.
Unpacking the technical mechanics behind colorful mug manufacturing, insulation science, and coating adhesion durability.
Our colorful mugs utilize high-purity Austenitic 304 (18% Chromium, 8% Nickel) stainless steel. This chemical composition provides exceptional resistance against intergranular corrosion caused by acidic beverages like coffee, tea, and citrus juices, eliminating metallic taste transfer.
We execute high-vacuum bake-out processes at temperatures exceeding 500°C to extract all air particles between the inner and outer walls. An inner copper-plated layer is applied to reflect radiant heat energy, securing thermal retention for up to 12 hours hot and 24 hours cold.
Our colorful finishings utilize eco-friendly electrostatic powder coatings, electroplated metallic gradients, 3D tactile UV printing, and heat-transfer dye sublimation. Coatings undergo 5B cross-hatch tape testing and dishwasher abrasion tests to guarantee zero peeling or fading.
How localized raw materials, automated manufacturing, and logistics integration deliver unrivaled wholesale competitiveness.
The manufacturing ecosystem in Wuyi County and neighboring Yongkang in Zhejiang Province accounts for a dominant share of global stainless steel insulated container production. Operating within this dense industrial cluster enables Wuyi Dongyi Dailysupplies Co., Ltd to leverage unmatched operational efficiencies:
Direct supply contracts with top-tier steel mills guarantee immediate access to premium 304/316 stainless steel coils. Bulk purchasing power mitigates global commodity price volatility, passing substantial unit cost savings to wholesale buyers.
Our in-house mold and tooling shop produces custom CAD-designed mug prototypes, ergonomic lid molds, and handle attachments within 7 to 10 days, significantly accelerating time-to-market for ODM clients.
From robotic hydroforming and automatic necking to laser trimming and automated powder-coating lines, automation minimizes human margin of error, securing a vacuum seal defect rate under 0.2%.
Located near Ningbo and Shanghai Ports, our factory streamlines ocean container loading, customs processing, and export clearance, reducing international shipping transit times.
Analyzing consumer trends, volume demands, and localized preferences across international markets.
High demand for 40oz and 30oz insulated quenchers featuring ergonomic handles, multi-position straw lids, and pastel matte finishes. Preferred for commuting, fitness, and vehicle cup-holder compatibility.
Focus on LFGB food safety compliance, zero-plastic packaging, and sleek 20oz skinny tumblers. High adoption among specialty coffee chains, outdoor gear brands, and eco-conscious retail markets.
Surging request for specialized 8oz Yerba Mate Gourds and compact coffee tumblers. Requires precise thermal wall insulation and custom vibrant color palettes catering to regional lifestyle traditions.
Meeting rigorous regulatory standards to ensure seamless customs entry and consumer safety worldwide.
Every product manufactured by Wuyi Dongyi Dailysupplies Co., Ltd undergoes third-party lab testing (SGS, TUV, Intertek) to certify complete compliance with global food-contact regulations:

100% thermal insulation testing, leak-proof pressure testing, and surface coating adhesion tests are executed before packaging.
Prompt ocean or air shipment with complete export documentation, customs clearance assistance, and ongoing after-sales support.
Detailed technical and commercial answers tailored for procurement directors, brand owners, and importers.
Our standard MOQ for stock color stainless steel tumblers and mugs starts at 500 units per model. For custom Pantone color spraying, powder coating, or specialized logo printing, the typical MOQ is 1,000 to 3,000 units depending on cup capacity and finish complexity.
Every mug undergoes two separate thermal testing procedures during production: first immediately after the high-temperature vacuum evacuation process, and second after surface coating assembly. Cups failing to hold heat/cold parameters are automatically rejected by infrared temperature sensors on the conveyor line.
We strongly recommend Electrostatic Powder Coating for dishwasher-safe colorful mugs. Unlike standard liquid paint, powder coating creates a thick, textured, polymer-based skin that withstands harsh dishwasher detergents and high thermal cycles without peeling, fading, or scratching.
Yes. All our products are crafted from premium food-grade 18/8 (304) stainless steel, and all plastic lids/silicone gaskets are 100% BPA-free. Our products routinely pass FDA, LFGB, and EU 1935/2004 chemical migration and heavy metal extraction tests.
Absolutely. Wuyi Dongyi Dailysupplies Co., Ltd maintains an active R&D department equipped with modern tooling machinery. We assist clients from initial CAD design to 3D rapid prototyping and final steel mold production for proprietary shapes, leak-proof straw lids, and heavy-duty handles.
Standard mass production lead time is 25 to 35 days after sample approval and deposit confirmation. For stock blanks requiring only custom logo laser engraving or screen printing, lead time can be expedited to 10–15 days.
