The stainless-steel vacuum flask is made of double-layer stainless steel inside and outside. The inner tank and the outer shell are combined by welding technology, and then the air in the interlayer between the inner tank and the outer shell is drawn out by vacuum technology to achieve the effect of vacuum insulation.

The Function of Stainless-Steel Vacuum Flask

Stainless steel thermos flask has the function of heat preservation and cold preservation. Ordinary thermo flask water bottle has poor heat preservation and cold preservation functions. The effect of vacuum insulated flask is much better. We can use vacuum flask to fill ice water or ice cubes on hot days, so we can enjoy the icy water at any time. In winter, we can fill in hot water, so that we can drink hot water at any time.


The steel vacuum flask can be customized according to requirements. Therefore, more and more people regard the stainless-steel vacuum flask as a gift for friends, customers and promotion. Put your own company information on the cup body or on the lid or send blessings and other content. This customized gift is being accepted by more and more people.



Features of Stainless-Steel Vacuum Flask

In fact, for vacuum steel bottle, the time of the holding temperature depends on the structure of the cup body and the thickness of the cup material. Generally speaking, the thinner the cup material, the longer the holding time is. But the cup body is easy to be damaged and deformed, which affects the service life. Measures such as covering the inner layer of the stainless-steel vacuum jug with metal film and copper plating can also increase the degree of heat preservation. Large-capacity, small-caliber vacuum cup has longer holding time, on the contrary, small-capacity, large-caliber vacuum cups have shorter holding time.


The service life of the ss vacuum flask also depends on the cleaning of the inner layer of the cup and the time for vacuuming. The most important thing is the structure of the vacuum furnace. The vacuum equipment used for vacuum insulation cups includes vacuum exhaust station and vacuum brazing furnace.

The brazing furnace is divided into single chamber, multi-chamber, and multi-chamber with increased pumping speed. The vacuuming cycle of this kind of furnace is long. If the manufacturer wants to improve production efficiency and shorten the vacuuming time, it will affect the service life of the cup, which is only about 8 years.


The thermos vacuum insulated flask produced by the vacuum exhaust table has a heating temperature of about 500°C during vacuuming. The outer shell of the vacuum cup is not easy to deform, but the copper pipe welding point is easy to leak. It must be specially protected during the processing of semi-finished products.


Although the vacuum flask water bottle we usually use is similar to general insulation cups in appearance, the production process of vacuum insulation cups is much more complicated than general insulation cups, and the technical difficulty is much higher. Therefore, the price of vacuum insulated cups is at least twice higher than that of general insulated cups.
