Frequently Asked Questions (FAQs)
Where are most hydro flask and vacuum insulated flask factories located in China
Most of the factories producing hydro flasks and vacuum insulated flasks in China are located in the Zhejiang Province, particularly in cities like Yongkang, which is often referred to as the “cup capital of China.” This region is home to hundreds of stainless steel vacuum bottle manufacturers, making it the largest production base for vacuum drinkware in the world[3][4].
What materials are commonly used in the production of flasks in China
Flasks manufactured in China are typically made from high-quality 18/8 food-grade stainless steel, also known as SUS304. This material is chosen for its durability, as it does not leach chemicals, stain, corrode, or rust. Additionally, the flasks are often double-walled and vacuum-insulated to maintain temperature efficiently[3][4].
What is the manufacturing process for vacuum flasks in China
The manufacturing process involves several steps
cutting stainless steel tubes to the desired length, shaping and welding the tubes, creating a vacuum between the walls, and then polishing and treating the surface. The flasks are also tested for leakage and temperature retention before final assembly and packaging. Advanced technologies like electrolytic polishing and mechanical polishing ensure a smooth and bright finish[4].
