Q&A: With the Cost of Helium Continuing to Rise, How Can Industrial Leak Detection Reduce Costs? Leak Tester Emerges as the Optimal Solution for Mass Production

This article provides a comparative analysis of the appropriate applications for helium mass spectrometer leak detectors and compressed air leak testers, pointing out that high-volume mass production lines do not need to blindly pursue the ultimate precision of helium testing; instead, adopting Jingcheng Engineering’s direct-pressure/ differential pressure/flow method, which not only meets industrial sealing requirements but also significantly reduces reliance on helium, improves production line efficiency, and achieves an optimal balance between cost and quality.

Quick Q&A: How does airtightness testing really work? How to define airtightness testing standards

This article introduces the principle of airtightness testing, steps, standard definitions and methods to ensure stable and reliable results. Airtightness testing is through the application of positive or negative pressure to monitor the pressure change to determine the sealing performance, divided into positive pressure method, negative pressure method and other ways, the process includes product positioning, inflation, pressure stabilization, testing and judgment. The development of standards requires comprehensive consideration of various factors. Precision Engineering can provide standardized and customized services for different enterprises, from experimental verification, jig design to mass production line data system integration.

How to choose waterproof test? Airtightness meter vs. soaking method vs. real water meter, see the wisdom of choosing airtightness measurement

The article introduces three airtightness measurement methods: airtightness tester measurement, direct soak method and true water leakage tester measurement, and analyzes them in four dimensions: product value, accuracy requirements, production scale and application scenarios. The airtightness tester is the mainstream choice for industry, with the advantages of non-destructive, accurate and efficient; the direct soak method is intuitive but inefficient and risky; and the true water leakage tester is suitable for high-level waterproof verification and leakage point localization.
