The World’s Largest Volume Vacuum Insulated Stainless Steel Water Jug

How Does a Vacuum Insulated Thermos Keep Its Temperature?

Before diving into the field of large volume insulated tumblers, let’s first learn how vacuum insulation is created.

1. First, an insulated stainless steel flask is built with a double-wall structure.

2. Then, in order to create a vacuum, the air between the inner layer and the outer layer needs to be pumped out. This process utilizes tail vacuum technology. The “tail” aspect refers to the method of extracting air from the bottom of the thermos through a narrow tube. This allows for more effective removal of air and ensures that the vacuum is maintained.

3. Next, once the vacuum is established, the open end of the thermos bottom is sealed securely, preventing air from escaping or entering.

This technique minimizes heat transfer through air conduction. It significantly enhances the insulation effect, keeping beverages hot or cold for longer periods.

Difficulties of Manufacturing Large Volume Insulated Water Bottle

1. Changes in Vacuum Pressure

When the capacity of an insulated cup increases, the changes in vacuum pressure can lead to the following effects:

• Increased Pressure Differential: A larger capacity means a bigger internal space. This requires more air to be removed, which increases the pressure differential between the inside and outside. As a result, it puts greater stress on the material.
• Higher Risk of Deformation: During vacuum extraction, the pressure differential increases. This can make certain parts of the cup, such as the bottom or sides, more susceptible to deformation. Thus, it affects the structural stability.
• Longer Vacuum Time: Larger capacities typically require more time to fully evacuate air, which can impact production efficiency.
• Thermal Expansion and Contraction: During pressure changes, the thermal expansion and contraction of materials may be exacerbated, potentially decreasing the final product’s sealing and insulation performance.
• Bubble Formation: Larger capacities may lead to more bubble formation. Any residual bubbles can compromise the integrity of the insulation layer. This reduces insulation effectiveness.

2. Out-of-Roundness

Roundness is a key quality metric in manufacturing, especially for insulated cups. Various measurement methods, such as roundness testers and CMM, are used to ensure compliance with industry standards (e.g., ISO, ASTM).

When the capacity of an insulated cup increases, a design with a large opening may lead to out-of-roundness:

• Material Stress: A higher risk of deformation can cause the bottle to lose its original circular shape.
• Mold Precision: If the mold design is not precise enough, a larger opening is more likely to deviate during molding, affecting the final shape.
• Thermal Expansion: During high-temperature molding, the material undergoes thermal expansion. This can lead to uneven contraction in the larger opening as it cools. As a result, the opening may become out of round.
• Vibration or Impact During Manufacturing: Larger components are more susceptible to vibrations or impacts during production, which can cause shape changes.
