Quick Question: Why do more and more manufacturing companies place more emphasis on source strength manufacturers when selecting an air tightness gauge?

This article discusses the shift in the logic of purchasing airtightness testers in the context of manufacturing upgrading: enterprises have shifted from simply comparing parameters and prices to selecting source strength manufacturers with process understanding, system integration and continuous service capabilities. The article takes Jingcheng Gongke JCGK as an example to illustrate how domestic manufacturers can replace imported equipment through the ability to deliver complete solutions, and become a long-term technology partner for manufacturing upgrades.

Precision Industrial Technology four-station automatic air tightness testing machine: food packaging lunch box sealing full inspection program review

This article reviews the Jingcheng Technology four-station automatic airtightness testing machine in the food packaging lunch box sealing the application of the full inspection. The article points out that sampling can not intercept the random distribution of sealing defects, the full inspection is the fundamental solution; through the actual test to verify that the equipment can be zero leakage judgment to identify trace leakage, and explains its independent four-channel, micro-pressure sensing and compensation algorithms, 72-hour stability verification of the three major technical support, as well as the production line adaptability and the head of customer cases.

Q&A: What are the requirements for the environment in which the airtightness tester is used? Please take this checklist

This article analyzes the environmental requirements for the use of airtightness testers, pointing out that temperature, humidity, air pressure and vibration are key variables that affect testing accuracy. The article emphasizes that high-precision testing is more sensitive to the environment, and provides a list of common problems in the production line environment, suggesting that priority be given to five aspects of temperature stability, air source dryness, airflow interference, product heat balance and tooling sealing, rather than rushing to replace the equipment.

From the Manhattan Project to Smart Manufacturing: A Look at the Past Life and Industrial Underpinnings of Airtightness Testers

This paper traces the evolution of airtightness testing technology from the birth of helium mass spectrometry leak detector of the Manhattan Project in 1943 to the present 80 years, analyzes the differentiation of pressure drop method, flow method and other technical routes, focuses on the waterproofing needs of smart phones and the development of new energy vehicles to promote the explosive growth of the industry, and points out that the Chinese manufacturers have been from the introduction of technology to the output of innovation, and the airtightness testing has become the invisible cornerstone of the quality control of the modern industry. It also pointed out that Chinese manufacturers have moved from technology import to innovation export, and airtightness testing has become the invisible cornerstone of modern industrial quality control.

Q&A: The higher the precision, the easier it is to misjudge? Uncovering the real stability logic of production line airtightness testing

This article exposes the "accuracy trap" in the procurement of leak tester, points out that marketing parameters such as 0.02% F.S. are misleading, and emphasizes that the detection stability depends on five system engineering factors: sensors, manifold seals, ambient temperatures, tooling and fixtures, and software algorithms. The authors propose that the selection should focus on the reading error (%rdg) and repeatability rather than full scale error, suggesting that the production line through the on-site testing to verify the performance, and that the domestic equipment in the system integration, cost-effective and service response has the strength to replace imports.

Military-grade reliability and industrial-grade mass production at the same time! Uncovering the technological evolution of domestic airtightness testing solutions

This article takes the rescue incident of the U.S. military pilot's distress device as an entry point to reveal the core root cause of the failure of outdoor electronic equipment - sealing reliability rather than chip performance. The article systematically describes the technical principle of airtightness testing, the transformation of industry standards from sampling to full inspection, and the technical maturity path of domestic solutions (taking Jingcheng Industrial Technology as an example), emphasizing that airtightness testing is a key process to guard the reliability of equipment.

Airtightness tester selection guide: direct pressure, differential pressure, volumetric method of the essential differences and practical choice

This article introduces the working principle, applicable scenarios and selection decision logic of the three commonly used methods (direct pressure method, differential pressure method and volumetric method) of the airtightness tester. The direct pressure method is suitable for products with holes, low cost but limited stability; the differential pressure method eliminates interference through comparative measurements, with an accuracy of 0.1 Pa, which is suitable for high-precision micro-leakage detection; the volumetric method is specially designed for fully enclosed products with no openings to realize non-destructive sealing inspection. Selection should be based on a combination of product structure, accuracy requirements and production line schedule to avoid falling into common traps such as "low price is enough" or "ignoring the jig".

Imported and domestic in the end how to choose? An article to speak through the airtightness market real stratification, must see before purchasing

This paper systematically analyzes the real stratification of the airtightness tester market, pointing out that the extreme precision scenario is dominated by European, American and Japanese brands, and the industrial mass production scenario prioritizes the evaluation of domestic head brands. The core selection principles are: do not look at the parameters to see the working conditions, do not look at the unit price to see the whole life cycle cost, through the real test to verify the stability of the equipment rather than superstitious publicity data.
