History of Airtightness Tester Development
With the advancement of industrial technology, the demand for airtightness testing technology and equipment has reached new heights. In civil industries, there is an increasing awareness and demand for understanding and controlling leakage, as well as for airtightness. However, the dangers and disasters caused by poor airtightness in products we are familiar with, such as motorcycles, cameras, cars, and gas appliances, have also served as a wake-up call. Especially recently, with the claims of water resistance and good airtightness in Apple, Samsung, and Huawei smartphones, the topic of airtightness has been pushed to the forefront by technology.
Traditional methods of sealed testing involve using tap water for the test, but there are many drawbacks to this approach: 1. The operation is very complex, requiring operators to submerge the products in water, and many products need to be dried after soaking. 2. Oxygen molecules are quite large, and small leak points are not detectable by water. 3. The detection of product leakage largely depends on the operator's visual observation, with a significant chance of misjudgment. 4. The testing speed is slow, making it incompatible with the rapid automation requirements of production. Due to these drawbacks, many manufacturers are now opting for more intelligent, faster testing methods with precise results.lAccurate Airtightness Tester.
Air compression, as a tasteless gas with molecules smaller than oxygen, and with graphite bipolar plates, offers higher precision in detecting product leaks. Additionally, air compression is less likely to cause secondary damage to tested goods, especially in electronic devices like watches where water exposure can cause irreparable harm to electronic components. Therefore, the sealability tester has many advantages over traditional tap water leak detection methods. For the sealability testing of various watches, the testing process typically consists of three steps:充入matching test pressure - pressure holding phase - testing phase.
