Airtightness testing machine

What are the methods for air tightness testing and which industries are suitable? Air tightness testing uses gas as the detection source to test the sealing of a certain container or pipeline. The pressure for air tightness testing should be higher than the usage pressure, and the application scope of air tightness testing is very wide, covering almost all industries. Below, the editor will explain its scope of use and methods to everyone.

There are too many uses and fields for airtightness testing equipment.

Airtightness testing industry:

Mobile phone industry: Waterproof and airtightness testing of mobile phone components such as the entire phone, lens, speaker, and card holder;

Electronic digital: waterproof and air tightness testing for smart bracelets/watches/laptops/speakers/Bluetooth earphones, etc;

Household appliances: waterproof and air tightness testing for electric toothbrushes/razors/water bottles/water dispensers/humidifiers, etc;

Automotive industry: Waterproof and airtightness testing for car lights/charging guns/car cameras/tires/water tanks, etc;

New energy industry: Waterproof and airtightness testing for lithium battery casings/new energy terminals/chargers, etc;

Industry: Waterproof and airtightness testing for thermometers/massagers/artificial dialyzers/endoscopes/infusion bags, etc;

Security lighting: waterproof and air tightness testing for cameras/smart door locks/intercoms/LED lights, etc;

Industrial machinery: waterproof and airtightness testing for various valves/water-cooled pipelines/vacuum pumps/die-casting parts, etc;

Wire connection: Waterproof and airtightness testing for camera connectors/audio connectors/wire terminal connectors, etc.

Airtightness testing method:

Pressure drop method: Depending on the airtightness pressure of different industries, the upper limit of the air pressure can be injected into the testing parts of different industries according to regulations, and then sealed for a specified holding time. After the time is up, check whether there is a pressure drop. If the pressure drops below the specified value or within the specified value, it is called pressure drop method.

Bubble method: Inject a certain gas pressure into the tested object, then immerse it in water or brush soapy water to see if there is any bubble.

Flaw detection method: Inject a certain amount of special gas into the tested object, and then use a special removal instrument to detect the special removal medium on the outer shell of the tested object. This method is generally used for special removal medium containers.
