In the design and production process of water bottles, sealing performance is a crucial indicator, which is directly related to the product's safety and user experience. Tritan water bottles are widely popular in the market for their excellent material properties and sophisticated sealing design. In order to ensure the reliability of these water bottles in various usage scenarios, manufacturers usually conduct a series of sealing performance tests.

The necessity of sealing performance testing is reflected in many aspects. Its main purpose is to ensure that the water bottle does not leak liquid during daily use, which is not only related to the basic functions of the product, but also directly affects the trust and satisfaction of consumers. Especially in outdoor activities, sports and travel, users have higher expectations for the sealing performance of water bottles. Therefore, it is particularly important to conduct comprehensive sealing performance tests.

There are many common sealing performance test methods, including pressure test, tilt test and temperature cycle test.

Pressure test is one of the basic methods to evaluate the sealing performance of water bottles. This test simulates the performance of water bottles under high pressure environment, and usually adopts the following steps: First, use a special pressure tester, set a certain pressure value (such as 0.5 to 1.5 bar), and then put the water bottle into the test equipment. Under the set pressure, keep a certain observation time (such as 30 minutes to 1 hour) to check if there is any liquid leakage. If any liquid leakage is found, it means that the sealing design is defective and needs to be improved. Through this test, manufacturers can effectively evaluate the ability of water bottles to withstand pressure during transportation and storage.

The purpose of the tilt test is to evaluate the sealing performance of water bottles at different angles, especially in situations that may be encountered during exercise or carrying. The test steps are as follows: fill the water bottle with water, fix it on the tilt test stand, gradually tilt the water bottle to different angles (such as 30°, 60°, 90°), and keep it at each angle for a period of time (such as 1 minute). After the test, check whether there is water leakage at the bottom and sides of the water bottle. This test helps manufacturers understand the performance of water bottles in daily use and ensure that users will not encounter leakage problems when exercising or walking.

The temperature cycle test is used to evaluate the sealing performance of water bottles under extreme temperature changes. This test is particularly important because water bottles may be used in different environmental conditions. The test steps include: using a temperature cycle box, placing the water bottle in the device, setting high temperature (such as 60°C) and low temperature (such as -20°C) for circulation, usually for 24 hours. After the temperature cycle, check the sealing performance of the water bottle to ensure that there is no liquid leakage. Through this test, manufacturers can fully evaluate the sealing performance of water bottles under extreme temperature changes and ensure the reliability of products under various climate conditions.
