Air Tightness Tester: Technical Solutions for Airbag Leak Testing - PLUS Automation

How is air tightness testing performed on flexible packaging products without damaging them? Currently, the method commonly used in the market is the air tightness testing method. To help everyone better understand flexible packaging air tightness testing methods, PLUS will now share with you air bags.Air leakage detectorCase Studies

Air tightness testing for air bags (also known as airbags) is performed to ensure that the air bag can effectively store and release gas to achieve its intended function. The following are some common technical solutions for air bag air tightness testing:

1. Pneumatic testing method: Inflate the air bag to a certain pressure, then observe the pressure change over a period of time to determine whether the air bag leaks. A pressure sensor or pressure gauge can be used for pressure measurement.

2. Bubble detection method: Immerse the air bag in water and observe whether bubbles emerge from the surface of the air bag. If bubbles emerge, it indicates that the air bag has a leak. This method is suitable for larger air bags.

3. Vacuum testing method: Place the air bag in a vacuum chamber, then determine whether the air bag leaks by detecting pressure changes inside the vacuum chamber. If the air bag cannot maintain a stable pressure inside the vacuum chamber, it indicates a leak.

4. Gas concentration detection method: Inflate the air bag to a certain pressure and inject a specific gas or gas mixture. Then use a gas concentration detection instrument to detect the gas concentration around the air bag. If the concentration decreases, it indicates that the air bag has a leak.

5. Thermal imaging inspection method: Use a thermal imager or infrared camera to detect temperature changes on the surface of the air bag. If there is a leak, the temperature around the leak point will change, and this change can be observed and recorded through thermal imaging technology.

The appropriate air tightness testing solution technology should be selected based on the specific airbag type and application scenario. Before conducting air tightness testing, it is advisable to refer to the relevant standards and specifications to ensure the accuracy and reliability of the test.
