In the field of civil machinery，In order to adapt to high performance，Low consumption，Low price and miniaturization requirements，The electronic components used are also made from diodes，The combination of individual components such as transistors is progressing to integrated circuits and then to large-scale integrated circuits..andVery large amountICshell，Ask for low price，High reliability，Also easy to operate，Therefore, the high-priced ceramic shells in the past will gradually be replaced by plastic shells.gluereplaced by shell.So how to test the overall sealing of a plastic shell that is being put into practical use?Today Shenzhen Hiraysi Automation Technology Co., Ltd.Just comeLet me tell you something。

when wePlastic caseWhen conducting air tightness testing, many customers will find during the testing process thatSince the internal space of the plastic case is very small, the detectionThe data becomes very unstable and the repeatability becomes very poor, resulting inFalse detectionofAffectioncondition.Developed independently by Hai Ruisi"IVT Pneumatic sealing valve island"The test accuracy is greatly improved, the stability of the instrument is ensured, and the inflation speed is also greatly improved.

Equipment used: HiraysHCClassic air tightness testing equipment 

Instrument range:-60-150KPA

Test pressure:15KPA

Testing method: The product has an inflatable port, and the direct inflatable test method is used.

As far as the above methods are concerned,During the testing phase,Fill the product according to the required test air pressure15KPAof compressed air，The entire test process is divided into inflation-voltage stabilization-Three stages of testing.After the test is completed, the instrument will automatically determine whether the sealing performance of the product meets the standard based on the data we set. If it meets the standard, the instrument will displayOK ,Otherwise, a beep will sound to indicate that the product is unqualified.

Air tightness testing is a very precise test. Any small changes will have a great impact on the test results. Therefore, in the air tightness testing, the selection of equipment, tooling, and parts should be done as much as possible.professionalsProduced after confirmation, byHirays TechnologyassistIt will be better to make them together laterEnsure test stability and accuracy。
