Air tightness testInstruments are collectively referred to asAir tightness detector、Tightness tester、Waterproof tester.Whether it is a finished product or a semi-finished product, it must reach a certain level of waterproofing or a certain level of safety.Air tightness testexperiment.

At present, the traditional sealing test on the market that we know is water testing.Air tightness testIn-depth research and development by instrument manufacturers has replaced it with a method of testing using compressed air.

Introduction to water testing methods:

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 appear, 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.

How to use compressed air for testing:

Use fixtures to seal the product and allow compressed air to pass throughAir tightness detectorEnter the inside of the test product or the inside of the mold.Air tightness detectorThe sensor senses changes in gas in real time, and finallyAir tightness detectorThe display shows whether the product is OK or NG.

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 kind ofAir tightness detectorIt has been widely used in many manufacturers and has been recognized by customers.

Of course this kindAir tightness detectorThe disadvantage is that there is no way to detect leaks.Technology is endless. I hope that in the near future, we can develop betterAir tightness detector。
