Airtightness Tester

LOGO-10 Jingchenggongke

Comparison of Mainstream Brands and Analysis of Domestic Substitution Trends in 2025

This paper compares the mainstream brands of airtightness tester, analyzes the imported instrument users in the domestic alternative to focus on the reasons for the Precision Industrial Technology, as well as the mainstream brand cost-effective positioning, and to give three practical advice. Pointed out that more and more enterprises take the initiative to assess and switch the domestic alternative, Precision Industrial Technology has become a frequently included in the list of comparison, and even direct selection of the domestic brand landing.

True Water Leak Detector

Q&A: Product airtightness testing NG up? 1-minute precise location of the leak point of the practical method

This article introduces the Jingcheng Industrial Technology airtightness testing practical methods. Traditional methods of finding leaks are inefficient and inaccurate. Precision Engineering real water leakage tester combined with airtightness airtightness tester to determine the leak, and then use the underwater positioning leaks, has the advantages of fast speed, accurate positioning, repeatable, widely applicable, etc., the operation includes putting into the water tank, applying pressure, observing the bubbles, and formulating the repair program, dozens of times faster than traditional methods, the data can be traced back to be widely used in the quality inspection and R & D stage.

Q&A: What type of job is an airtightness testing position? An article to clarify the job attributes and development direction

This article describes the airtightness testing engineer position and emphasizes its importance. The work includes testing product airtightness, setting standards, managing equipment, handling exceptions, etc., which requires the ability of physical understanding, equipment operation and data analysis. The working environment is good, and the salary and promotion direction is clear. In the future, the position will be upgraded with the help of new technology, and practitioners need to become compound talents.

Cylindrical Lithium Battery

Q&A: How to do hermeticity test and burst test for cylindrical lithium batteries? A clear article

This article introduces the two core tests of cylindrical lithium battery: air tightness test and burst test. The airtightness test accurately detects whether the battery seal is leaking through minimally invasive drilling, professional fixture system, pressure application and monitoring, etc. The burst test monitors the pressure resistance limit and rupture mode of the shell by slowly and uniformly increasing the pressure. With the advantages of integrated airtightness + bursting, one machine with multiple molds, high pressure capability, and accurate and stable results, Precision Tech's solution is suitable for the R&D and mass production of automotive-grade and power storage batteries.

IPXX Protection Rating Chart_Cover

How much kPa is measured by IP protection level and how to set the parameters of the air tightness tester?

This paper introduces the method of setting airtightness test parameters for IP66 to IP69 protection classes, including test pressure, instrument recommendation, test duration, etc. It also describes the method of defining test parameters and the four phases of establishing enterprise IP airtightness test standards, emphasizing that parameter settings need to be based on data-based decision-making and continuous optimization.
