Currently, the testing methods of air tightness testing equipment on the market are mainly divided into three types: bubble detection method, pressure drop detection method, and differential pressure air tightness detection method.The current mainstream method of using air tightness testing equipment on the market is the pressure drop testing method.The air medium pressure drop method has high efficiency, strong versatility, high detection rate, and non-destructive testing. Among them, the multi-channel air tightness detector can detect multiple products at the same time, which is the current mainstream air tightness detector detection method.

Air tightness testing equipment is currently classified according to pressure on the market. We can divide it into three types: low-pressure type, general-purpose type, and high-pressure type. They can be purchased according to actual use needs. The corresponding parameters are shown in the table below:

The parameters of ultra-high pressure leakage tester are not listed here. If necessary, please communicate with Hirays Technology in advance to determine the corresponding parameters.

When completing the test process of the entire air tightness detection system, we need to prepare a leak tester, air source, and test fixture, and combine them to complete the test.in:

1. The test fixture should be customized according to the characteristics of the product being tested;

2. Air source part

(1) The air supply pressure of the host is 0.4~1.2MPa, and cannot be used beyond this range; the working air pressure of the test fixture is adjusted between 0.4~0.5MPa, otherwise the cylinder may not be pressed tightly against the mold, affecting the sealing effect.

(2) The air source must be stable, and the fluctuation cannot exceed 50Kpa, otherwise it will affect the test results; (3) The compressed air must be dry, moisture-free and impurity-free, otherwise it will easily damage the internal pipeline of the leak tester.

Hirays air tightness tester has a wide range of applications and can be used in

Mobile phone industry (mobile phone back cover/middle frame, waterproof of the whole machine, various waterproof parts, waterproof mobile phone case products) as shown in the figure;

Automotive industry (tire pressure, car cameras, car lights, controllers, car pipelines, charging guns, etc.);

Battery industry (battery packs, lithium battery casings, terminals and casings, battery chargers, etc.); home appliance industry (home controllers, coffee machines, juicers, blenders, kettles, electric toothbrushes, etc.);

Smart wearable industry (smart bracelets, watches, underwater alarms, etc.);

Audio industry (sports audio, Bluetooth speakers, Bluetooth headsets, etc.);

Outdoor security industry (LED lights, outdoor cameras, smart door locks, outdoor controllers, communication base stations, underwater alarms, etc.); military supplies industry (fuses, walkie-talkies, handheld walkie-talkies, vehicle-mounted walkie-talkies, three-proof mobile phones, etc.);

Medical device industry (sphygmomanometer, electronic thermometer, endoscope capsule and various infusion and oxygen tubes);

Wiring harness industry (waterproof connectors, waterproof wires, etc.).

Other industries (valve sealing, pipe permeability, joint sealing testing);

Above, we have introduced the use of air tightness testing equipment and the application cases of air tightness testing equipment in the industry. We hope it can help everyone.
