As a supplier of 18/8 Vacuum Thermos, I often receive inquiries about the vacuum - holding time of our products. The vacuum - holding time is a crucial factor that determines the performance and longevity of a vacuum thermos. In this blog, I will delve into what the vacuum - holding time of 18/8 Vacuum Thermos is, the factors that affect it, and how it relates to the overall quality of our thermoses.
What is Vacuum - Holding Time?
The vacuum - holding time refers to the duration for which the vacuum within the thermos is maintained at an effective level. In a 18/8 Vacuum Thermos, the inner and outer walls are made of 18/8 stainless steel, which is known for its excellent corrosion resistance and durability. A vacuum layer is created between these two walls. This vacuum acts as an insulator, reducing heat transfer through conduction and convection.
The longer the vacuum - holding time, the better the thermos can keep hot liquids hot and cold liquids cold. For example, if a thermos has a long vacuum - holding time, it can maintain the temperature of hot coffee at an acceptable level for several hours, even in a cold environment.
Factors Affecting Vacuum - Holding Time
Manufacturing Quality
The manufacturing process plays a vital role in determining the vacuum - holding time. At our production facility, we use advanced techniques to create a high - quality vacuum between the two stainless - steel walls. Any tiny leak or imperfection during the manufacturing process can significantly reduce the vacuum - holding time. For instance, if there is a small crack in the seal where the inner and outer walls are joined, air can slowly seep into the vacuum layer, gradually diminishing its insulating properties.
Material Quality
The quality of the 18/8 stainless steel used also impacts the vacuum - holding time. High - grade 18/8 stainless steel is less likely to develop microscopic pores or cracks over time. These pores can allow air to enter the vacuum chamber, reducing its effectiveness. Our company sources the best 18/8 stainless steel materials to ensure the long - term integrity of the vacuum in our thermoses.
Usage and Maintenance
How the thermos is used and maintained can also affect the vacuum - holding time. Rough handling, such as dropping the thermos or subjecting it to extreme impacts, can damage the vacuum seal. Additionally, improper cleaning, like using abrasive cleaners that can scratch the stainless - steel surface, may lead to air leakage. We recommend gentle cleaning with mild detergents and soft sponges to preserve the vacuum - holding ability of our thermoses.
Measuring Vacuum - Holding Time
There are several ways to measure the vacuum - holding time of a 18/8 Vacuum Thermos. One common method is to fill the thermos with hot water at a specific temperature and then monitor the temperature change over time. If the temperature drops rapidly, it indicates that the vacuum is not being maintained effectively, and the vacuum - holding time is short.
Another approach is to use specialized equipment to detect the presence of air in the vacuum layer. This can provide a more accurate assessment of the vacuum's integrity. At our company, we conduct rigorous quality control tests using both temperature - monitoring and air - detection methods to ensure that each thermos meets our high - standards for vacuum - holding time.
Our 18/8 Vacuum Thermos Products
We offer a wide range of 18/8 Vacuum Thermos products, including the Insulated Thermos Vacuum Flask, the 500ml Double Wall Stainless Steel Flask, and the Vacuum Thermos Flask. Each of these products is designed to have an optimal vacuum - holding time.

Importance of Vacuum - Holding Time in Our Products
The vacuum - holding time is a key selling point for our 18/8 Vacuum Thermos products. Customers expect a thermos to keep their drinks at the desired temperature for a reasonable amount of time. A long vacuum - holding time means that our customers can enjoy hot coffee in the morning or cold water in the afternoon, no matter where they are.
In addition, a long vacuum - holding time reflects the overall quality of our products. It shows that we pay attention to every detail in the manufacturing process, from the selection of materials to the final assembly. This commitment to quality has earned us a good reputation in the market, and many customers come back to us for repeat purchases.
How We Ensure Long Vacuum - Holding Time
To ensure a long vacuum - holding time for our thermoses, we have a strict quality control system in place. Every step of the manufacturing process is closely monitored, from the initial cutting of the stainless - steel sheets to the final testing of the finished product.
We also invest in research and development to continuously improve our manufacturing techniques. For example, we are constantly exploring new ways to create a more perfect vacuum seal, which can further extend the vacuum - holding time of our thermoses.
