Explore our core engineered vacuum insulated tumblers, sports flasks, and custom drinkware containers manufactured to strict international quality standards.
Understanding user intent, technical specifications, and market requirements for international B2B buyers and brand owners.
In the global commercial drinkware and personal hydration sector, the 500ml water bottle (16.9 fl oz) stands as the universal baseline standard. It strikes the perfect balance between liquid capacity, portability, ergonomic grip, and thermal management efficiency. Enterprise buyers, retail brand managers, FMCG distributors, and corporate gift procurers prioritize 500ml double-wall vacuum insulated stainless steel bottles due to their versatile fit across diverse daily user scenarios—ranging from corporate desktop hydration and fitness training to outdoor adventure and commuter lifestyles.
Private label retailers require high-precision OEM customization, including exact Pantone color matching, silk-screen printing, 3D UV printing, and custom retail packaging engineered for e-commerce unboxing experiences.
Performance hydration demands lightweight yet rugged construction. Rugged powder-coated 500ml flasks featuring leak-proof carabiner caps, wide-mouth ice compatibility, and sweat-free vacuum insulation lead sport sales globally.
Global corporations replacing single-use plastics seek eco-conscious, long-lasting 18/8 stainless steel 500ml bottles that align with environmental stewardship metrics and present high perceived brand value.
Technical specifications and material science details powering our high-performance thermal insulation products.
At Wuyi Dongyi Dailysupplies Co., Ltd, our manufacturing methodology centers on rigorous structural metallurgy and automated vacuum processing. Our 500ml stainless steel water bottles and vacuum insulated tumblers undergo a multi-stage deep-drawing, spinning, and annealing process to optimize wall thinness while retaining physical rigidity.

Our automated high-vacuum baking ovens evacuate air between the inner and outer steel walls at 500°C, reaching internal pressures of less than 10⁻³ Pa for maximum thermal insulation performance.
State-of-the-art robotic laser welding creates smooth, practically invisible joints on bottle shoulders and bases, preventing structural fatigue and ensuring lifetime vacuum integrity.
Electrolytic passivation cleans and smooths the internal stainless steel surface, removing microscopic micro-pores to prevent bacterial growth and eliminate residual beverage odors or stains.
