How long does a thermos cup last? In order to give you an objective analysis, we have to disassemble the thermos cup for analysis.The thermos cup consists of a lid and a body.The material of the cup body is mainly stainless steel. At present, many factories in the market use 304 stainless steel. Production process Cup body liner usually adopts electrolysis process and vacuuming process. Taking 304 stainless steel as an example, it can be used for more than 5 years if it is properly maintained without the corrosion of acid and alkaline substances. The electrolytic process will receive acid corrosion of beverages during use and will also be damaged due to improper cleaning methods.

In the case of reasonable use, the electrolytic coating can be used for more than 3 years. The purpose of the vacuuming process is to make the thermos cup achieve the best thermal insulation function. The vacuuming process will gradually destroy the vacuum during use due to the lax production, and will also cause damage due to the fall of the water cup during later use. However, in the case of strict production process and careful use in the later period, the vacuuming process can usually be guaranteed to be used for more than 3 years.

The lid of the cup is made of plastic as an example. Different plastic materials have different service lives, especially if the lid has an opening and closing function, the factory will do a life test before leaving the factory. Usually, the test standard is 3,000 times. If a water glass is used about ten times a day, three thousand times can meet the needs of a year of use. But three thousand times is only the minimum standard, so a qualified lid combined with a reasonable structure can usually be used for more than 2 years.
