Air tightness tester is also called sealing tester and leakage tester. Hirays Technology air tightness tester has a wide range of applications, covering various components in the mobile phone industry, various components around the automotive industry, as well as batteries, home appliance industry, smart wear industry, consumer electronics industry, outdoor security industry, military supplies industry, medical equipment industry, valves and pipelines and other industries.About the method of air tightness testing, andAir tightness testing solutionAnd principles, in order to let the industry have a better understanding, Hirays Technology will introduce it to you below.

At present, there are two main methods of air tightness testing: one is testing with water, and the other is testing with compressed air.

The method of water testing is: block the sealing port of the product, place the product directly in the water, inject gas from the inflation hole of the product, and observe whether bubbles emerge from the product. If bubbles emerge, it means the product is leaking. The more bubbles, the larger the bubbles, the greater the leakage.

This method of testing product sealing with water is relatively intuitive, and the leakage point of the product can be observed.The disadvantage of this detection method is that the tested products need to be dried, and it takes a long time to test a single product from testing to drying; some electronic products will be damaged by water, so that the product not only leaks but also the internal electronic components are damaged by water, making repair more difficult.Therefore, many companies no longer use this method when conducting air tightness testing on large quantities of products.

The method of testing with compressed air is to use a tooling fixture to seal the product, and the compressed air enters the inside of the test product or the inside of the mold through the air tightness detector.The sensor of the air tightness detector senses changes in the gas in real time, and finally the air tightness detector displays whether the product is OK or NG through the display screen.

This air tightness testing method using compressed air as the medium has many advantages: first, it is a non-destructive testing, because the testing medium is air, and air will not cause damage to the product; second, because air molecules are smaller than water molecules, the testing results are more accurate; the operation is relatively simple, and the testing process is fast.This air tightness detector has been widely used by many manufacturers and has been recognized by customers.

Of course, the disadvantage of this air tightness detector is that it cannot detect leaks.Technology is endless. I hope we can develop a better air tightness detector in the near future.

Shenzhen Hiraysi Technology has specialized in air tightness testing for 11 years and has provided air tightness testing equipment to more than 1,000 customers.More than 3,000 sets of air tightness testing equipment are in place to ensure the air tightness and waterproof functions of customer products.
