Do you want to know how a thermos bottle works? The main factor we consider when choosing a water bottle or cup is the vacuum insulation properties. If you don't know what insulation means or what a double cup is, you've come to the right place. It is important for customers to understand these issues before making a final order.

The function of the thermos cup is to prevent the heat exchange between the objects stored inside and the external environment. Therefore, the thermos cup can be used to keep warm and cold, but it cannot completely prevent the heat exchange between the inside and the outside. In the end, the temperature inside and outside still remains. will tend to be equal.

This article will explain to you in detail the working principle of thermal insulation and how our water bottle factory ensures excellent thermal insulation performance.

What does vacuum insulation mean?
The thermos cup is composed of a double-layer stainless steel thermos cup body, plastic parts, and sealing rings. The double-layer stainless steel cup body needs to go through more than a hundred processes to produce a qualified vacuum thermos cup. We all know that the vacuum insulated cup has three major functions: heat preservation, cold preservation, and freshness preservation. In addition to the above three functions, it also has the following functions:

The vacuum thermos cup can maintain the temperature of water and food in the container for a long time, making it convenient for users to enjoy hot food or hot drinks at different times and in different spaces, which is conducive to improving people's quality of life.

Most knowledge brand vacuum flasks are made of 304 stainless steel, which will not produce harmful substances and odors during use. The vacuum flask's insulation of drinking water can avoid damage to water quality caused by repeated boiling of water.

Promoting the use of vacuum insulated cups can effectively reduce environmental pollution caused by waste from disposable plastic containers and paper cups, and reduce the consumption of natural resources such as oil, wood, and water in the production of plastic containers and paper cups. At the same time, the stainless steel vacuum insulated cup can be kept warm for a long time, reducing repeated heating caused by power consumption.

The waste of disposable bottled water is serious. Using vacuum thermos cups instead of disposable plastic containers also effectively reduces the waste of water resources. It can be said that one thing has multiple uses and caters to the actual needs of the people. There are enough choices.

We ensure that all raw materials are tested and qualified before entering the manufacturing stage. We have more testing procedures to ensure the reliability of raw materials. Our inspection technology provides accurate data readings, backed by the keen sense of our inspectors, allowing us to faithfully meet your specifications. The key to our success in manufacturing high-quality products lies in strict inspection of each process.

Gint water bottles feature a double-wall vacuum seal, ensuring you experience zero condensation and your beverage temperature remains constant in the insulated chamber. We will conduct three vacuum tests to ensure that all water bottle products can maintain a long-term vacuum state. Double-walled vacuum insulated water bottles keep liquids hot or cold for longer. A well-insulated bottle will pass through a customer's filling line without any difficulty and will also have the quality to safely ship their product to the consumer. Therefore, before water bottles are shipped from the stainless steel water bottle factory, they must successfully pass functional standard inspections that meet customer needs.

From the professional perspective of thermos cup manufacturers and combined with the popularity of the market, we have sorted out the best stainless steel thermos cups in batches.

How does vacuum insulation work?
The thermos cup adopts a double-layer structure, and the vacuum in the inner tank and cup body can prevent the transfer of heat. Whether the sealing performance of the thermos cup is good also plays a very important role in the insulation effect. The better the sealing, the harder it is to transfer heat and the better the insulation effect.
Vacuum does not transfer heat; it is equivalent to cutting off the heat-conducting medium. The higher the vacuum, the better the insulation effect. Vacuum technology is divided into two types: tailed vacuum and tailless vacuum. Nowadays, most vacuum flask manufacturers use tailless vacuum because this technology is relatively advanced.
