With the improvement of waterproof test technology for air tightness detection. Many parts in cars are easily damaged by water, so the use of water to test the tightness of auto parts has been abandoned by many manufacturers. The air tightness detection is more efficient and scientific than traditional water, and will not cause secondary damage to the product. At the same time, the air tightness tester uses compressed air as the detection medium. The molecules of air are much smaller than those of water, and the accuracy is higher, and the accuracy is in the tens of thousands.

As the main vehicle for daily travel, the safety of the car has always been a very important quality assurance for consumers and manufacturers. The waterproofness and airtightness of auto parts are related to the safe driving of cars. Sometimes a small part is not waterproof, and the poor sealing performance may cause huge security risks. Therefore, it is very important to conduct airtightness testing and airtightness testing of auto parts.
