Engineered for high thermal efficiency, exceptional aesthetics, and global compliance standards.
Understanding thermal mechanics, material metallurgy, and global supply chain dynamics for B2B procurement decision-makers.
In the modern global consumer market, the term "pretty mug" has evolved beyond simple visual appeal into a complex convergence of ergonomic design, thermal material science, advanced powder-coating metallurgy, and food-grade safety compliance. Global consumers no longer compromise utility for aesthetic design; they demand sleek aesthetic profiles, trendy colorways (such as muted pastels, iridescent gradients, and tactile matte finishes), combined with 24-hour thermal containment performance.
As a premier ODM/OEM manufacturer situated in Wuyi County, Zhejiang Province, Wuyi Dongyi Dailysupplies Co., Ltd stands at the forefront of this industrial transformation. We engineer double-walled stainless steel mugs, skinny tumblers, hydra quenchers, and egg-shaped cups that seamlessly harmonize striking visual elegance with institutional-grade structural durability.
Technical Insight: Our thermal retention metrics achieve less than 1.5°C dissipation per hour for hot beverages over an 8-hour window, backed by copper-plated inner wall radiation barriers and high-vacuum furnace extraction operating at 10⁻⁴ Pa pressure.

Delivering turn-key ODM/OEM capabilities for international brands, retail chains, and corporate distributors.
We provide full-spectrum structural and aesthetic customization. Utilizing precision laser etching, gradient sublimation, tactile 3D powder coating, and custom functional lids (straw flip, leak-proof magnetic sliders), we translate brand concepts into market-ready retail products.
Every batch undergoes stringent quality control protocol: 3-stage vacuum leakage testing, 48-hour salt-spray corrosion analysis, drop impact resistance tests, and lid seal torque evaluation to guarantee zero-defect delivery.
Equipped with modern high-speed automatic cold hydroforming presses, continuous vacuum sintering furnaces, and automated robot painting lines, our facility handles high-volume seasonal spikes with predictable lead times and reliable logistics scheduling.
Full documentation support including Certificate of Origin, FDA material safety testing, LFGB compliance certificates, and customs clearance assistance across North America, Europe, South America, the Middle East, and Southeast Asia.

Wuyi Dongyi Dailysupplies Co., Ltd is strategically located in the industrial cup-manufacturing hub of Wuyi County, Zhejiang Province, China. We specialize in the research, development, structural engineering, and automated production of food-grade stainless steel tumblers, pretty mugs, sports bottles, insulated cups, jugs, and double-walled vacuum food containers.
Operating on the unyielding corporate tenets of "Quality First, Service First," our factory houses advanced high-tonnage hydraulic presses, ultra-clean dust-free polishing workshops, automatic laser welding machinery, and stringent quality testing labs. Over the past decade, we have established long-term strategic partnerships with leading importers, brand owners, and retail chain buyers across the United States, European Union, South America, Middle East, and Southeast Asia.
Full process inspection from raw SUS304 coil to packed carton.
Patented lid structures, ergonomic handles & durable coatings.
Pioneering smart thermal features, circular material innovation, and ultra-durable eco-friendly coating technologies.
Integrating ultra-low-power micro-sensors within lid structures to display real-time internal liquid temperatures via discrete touch LED displays, preventing accidental scalding while tracking daily hydration goals.
Incorporating up to 90% Post-Consumer Recycled (PCR) stainless steel in non-food contact outer shells, reducing manufacturing carbon footprint by 45% without diminishing structural tensile strength or thermal performance.
Plasma-Enhanced Chemical Vapor Deposition allows micro-thin ceramic interior coatings. This provides an absolute inert surface for delicate beverages like specialty pour-over coffee and matcha, leaving zero metallic residual taste.
Essential technical and commercial insights for wholesale importers, brand owners, and procurement managers.
All our products are manufactured using food-grade SUS304 (18/8) stainless steel and BPA-free Tritan/AS plastic lids. Our manufacturing line fully complies with U.S. FDA 21 CFR 175.300, European LFGB standards, EU Regulation No 10/2011, and CE certifications. Certified test reports are provided with every order production batch.
Our baseline MOQ for standard stock colors with custom laser logo engraving starts at 500 units per style. For fully custom Pantone color matching, complex powder coat gradients, or custom box packaging, our standard MOQ is 1,000 to 3,000 units depending on cup geometry and decoration technology.
Our high-vacuum copper-lined construction maintains hot beverages above 60°C for up to 12 hours and iced drinks below 8°C for over 24 hours under standard ambient laboratory testing conditions (20°C ambient room temperature).
Yes. We utilize advanced automated powder coating, electroplating, UV digital printing, and hydro-graphics transfer. Clients simply supply a Pantone (C/TPX) color reference code, and our color laboratory yields a 99% precise match verified by spectrophotometer inspection.
Existing sample delivery takes 2 to 4 days. Customized pre-production samples with custom logo/coating take 7 to 12 days. Full mass production lead time averages 25 to 35 business days following sample approval and deposit confirmation.
We implement a dual getter-alloy absorption system inside the double-wall space combined with high-temperature vacuum degasification during furnace extraction. Furthermore, 100% of finished bodies pass through automated thermal sensor channels twice during production to discard micro-leaks.
