As mobile phones play an increasingly important role in people's lives, the waterproof performance of mobile phones has also become a major selling point of mobile phones.. Many brands of mobile phones have reached theIP67 waterproof rating, splash-proof, water-proof and dust-proof.However, mobile phone manufacturers are not satisfied with this. They challenge the waterproof level of mobile phones to IP68, so that the mobile phones can be immersed in water without being immersed in water.

In order to detectWaterproof rating of mobile phoneWhether the requirements are met, the current cost-effective method is to use air tightness testing equipment (also known as waterproof testing equipment).

Today we are sharing aboutMobile phone air tightness testingcase.

Equipment used: Hirays HL Leader SeriesAir tightness detector

Testing method: Direct testing method is adopted. According to the overall structure of the mobile phone and customer requirements, the product reaches IP68 waterproof level, and the fixtures and tooling are customized.Select the set program and start testing.

Program parameters: air intake pressure 15Kpa, air intake time 8s, pressure stabilization 8s, test time 5s, quantitative air intake 5s, partial pressure time 5s, deflation time 3s.If the leakage value does not exceed 20pa, it means that the air tightness test of the test product has passed, and the test result will also show OK.

Hirays HL Leader Classic Series Air Tightness Detector

1.     The mold processing accuracy is high, up to 0.02mm;

2.     Air tightness detector with resolution up to 0.1pa;

3.     Hirays has more than 30 mold design engineers and a strict evaluation system;

4.     When you need service, scan the QR code of the device and talk directly to the after-sales service staff of Hirays, refusing to wait;

5.     The detection system designed by Hai Ruisi strictly considers the stability and accuracy of the test results.

The air tightness testing equipment developed by Hirays is a non-destructive testing instrument. It uses compressed air as the testing medium, which will not cause secondary damage to the test product. The testing accuracy can reach 1pa. The test data can be exported to the computer, and the quality of the product can be traced. Currently, a multi-channel air tightness testing equipment has been launched. One device can test multiple products, which greatly reduces the cost of product air tightness testing.
