Engineered with double-wall food-grade 18/8 (SUS304) stainless steel, precision copper lining, and advanced thermal retention dynamics for global corporate gifting.
Leading the global drinkware manufacturing sector through metallurgical innovation, continuous research and development, and strict ISO-aligned quality engineering.
Situated in Wuyi County, Zhejiang Province—the global epicenter of stainless steel vacuum hardware manufacturing—our facilities leverage an advanced regional industrial ecosystem to ensure rapid raw material processing and optimized export logistics.
We specialize in processing food-grade 18/8 (SUS304) and premium medical-grade 316 stainless steel. Every batch features high nickel-chromium ratio protection, preventing oxidation, metallic leeching, and corrosion under acidic beverage conditions.
Our automated high-vacuum bakeout kilns evacuate thermal transference air channels down to 10⁻² Pa. Combined with inner wall copper plating, our mugs maintain cold temperatures for up to 36 hours and hot retention for up to 12 hours.
Wuyi Dongyi Dailysupplies Co., Ltd operates strict Quality First, Service First management systems. Our fully integrated production facility handles everything from metal spinning, hydroforming, and automated robot polishing to electrostatic powder coating and custom gift box packaging.
How modernized industrial clusters in Zhejiang enable zero-defect production, cost stabilization, and rapid market turnaround for international B2B buyers.
In the competitive corporate promotional and retail drinkware sector, securing high-yield manufacturing partners with robust supply chain elasticity is paramount. Operating from Zhejiang Province, Wuyi Dongyi Dailysupplies Co., Ltd bridges advanced automated hardware fabrication with digitalized quality assurance networks.
Traditional deep-drawing can stress steel, leading to micro-fractures. Our lines utilize automated hydroforming and precision fiber-laser seam welding. This reduces stress cracking, guarantees flawless wall uniformity, and ensures air-tight structural integrity for double-wall vacuum vessels.
Vacuum thermal insulation depends on the complete removal of air and moisture trapped between vessel walls. Our factory utilizes high-capacity continuous vacuum bakeout furnaces operating at 1050°C, installing getter materials to absorb residual gas molecules across the product lifecycle.
By controlling raw material sourcing, mold fabrication, surface finishing (powder coating, UV 3D printing, water transfer printing), and packaging assembly under one integrated management protocol, we shield clients from supply chain disruptions and volatile lead times.

Food-grade 18/8 (SUS304) stainless steel contains 18% chromium and 8% nickel. This metallurgical ratio forms a self-healing passive oxide layer preventing rust, oxidation, and metal leaching into hot or acidic beverages. It offers superior durability, impact strength, and flavor neutrality compared to cheaper 201 series steel.
We provide comprehensive customization: custom pantone color matching (spray paint, powder coating, gradient finishes), logo application methods (laser engraving, screen printing, 3D UV printing, water transfer), functional lid variations (straw lids, sip lids, magnetic sliders), and customized gift packaging (FSC-certified paper boxes, luxury rigid boxes, custom EVA foam inserts).
Double-wall vacuum insulation features a sealed airless void evacuated to 10⁻² Pa between two stainless steel walls. This eliminates conductive and convective heat transfer. Combined with inner wall copper coating that reflects thermal radiation, our vacuum tumblers keep drinks cold for up to 36 hours and hot for up to 12 hours, while keeping the outer shell sweat-proof and cool to touch.
Our standard production MOQ ranges between 1,000 to 3,000 units depending on color complexity and custom tooling requirements. Sample production takes 5 to 7 business days, while full mass production turnaround is typically 25 to 35 days from sample sign-off and deposit receipt.
Yes. All raw materials and finished products undergo rigorous third-party testing (SGS, Intertek, TÜV). Our items comply fully with US FDA, European LFGB, REACH, RoHS, and CE standards, ensuring 100% BPA-free, non-toxic, and heavy-metal-free compliance.
