Computer screens are generally used in living environments and industrial environments, and most computers are directly exposed to the outside.
It is very easy to live in the same environment with water. In order to ensure the service life of the display screen, which we often call the computer screen, the computer screen needs to have high waterproof requirements.
Below, Hirays Technology will show youComputer screen air tightness testingcase.
The customer requires that the kit can withstand a pressure of 200Kpa, which is the IP68 waterproof level test of the kit.
Equipment used for air tightness testing: HD Ingenuity SeriesAir tightness detector
Testing method: Use semi-finished product and negative pressure test method. According to the shape and structure of the computer screen, sealing ring + mold are used to seal the product to be tested, so that it forms a closed cavity during testing.
Put the computer screen into the mold for testing.The test pressure is -10Kpa , the maximum allowable leakage is 50pa. The air intake time is 15s, the pressure stabilization time is 15s, the test time is 5s, and the deflation time is 2s.
As a result, the equipment automatically determines that if the leakage value does not exceed 50pa, the tested product passes the waterproof test, otherwise it fails and the tested product is defective.

HD ingenuityseriesAdvantages:
High resolution: 0.1pa,Hirays air tightness instrumenthighest resolution;
High stability: differential pressure principle, simultaneous comparison of both sides;
Quick to get started: No need to click any buttons, just enter the pre-test settings and adjust the pressure;
There are no special requirements for pressure regulating valves: ordinary SMC/CKD valves can meet the needs;
The test method is reasonable: the finished product has a large leakage and the volume is determined;
Save long-term use costs: No matter whether you are testing finished products or semi-finished products, you only need to connect one mold (except for large products and high-expansion products).
HD ingenuityseriesAdvantages:
Support seamless switching with F28;
Differential pressure testing method has high accuracy and better stability;
The software automatically compensates for test differences caused by temperature rise caused by long-term operation of the solenoid valve;
Provide PC-side Demo program to facilitate secondary development;
Very competitive price.
Benefits of HD Craftsmanship Series:
Shorter delivery time enables faster delivery of projects;
Local technical support provides a better software and hardware development experience;
Provide PC-side Demo program, which can save software engineers more time;
Worry-free after-sales service and two-year warranty;
More competitive prices ensure greater benefits for the project.
