Q&A: Why Do New Energy Vehicles Need to Undergo Comprehensive Airtightness Testing? To Avoid the Risk of Large-Scale Recalls

Taking the recall of 33,473 Xpeng X9 vehicles due to air spring airtightness defects as a starting point, this article analyzes the importance of airtightness testing for new energy vehicles. The article points out that core components of new energy vehicles demand higher standards for sealing reliability, driving the transition from spot checks to 100% inspection for airtightness testing. It introduces two testing principles—the direct pressure method and the differential pressure method—and uses the Jingcheng Engineering JC-C10005 series as an example to demonstrate that domestically produced equipment has achieved high-precision micro-leak detection, wide pressure adaptability, and automated integration into production lines.

Who is Jingcheng Engineering (JCGK)? A domestic air-tightness testing brand dedicated to helping the manufacturing industry detect leaks.

This article introduces JCGK, founded in 2016, a leading domestic brand of airtightness testing equipment that specializes in helping manufacturing companies identify the risk of micro-leaks in their products through airtightness leak detection, sealing tests, and other technologies. Its core strengths lie in independent R&D, production line integration capabilities, and localized services. The company’s business spans multiple industries, including new energy, automotive, consumer electronics, medical devices, and liquid cooling, and is committed to providing end-to-end reliability assurance—from product testing to the establishment of quality management systems.

Quick Q&A: Reliability Validation in the Waterproof and Breathable Membrane Industry—How Can Two Conflicting Properties Be Tested at Once?

This article explains how the waterproof and breathable membrane industry can simultaneously verify the two conflicting properties—waterproofing and breathability—through a comprehensive testing solution. Addressing the “water-blocking yet breathable” characteristics of ePTFE membranes, JCGK has proposed an integrated testing solution that resolves the issue of trade-offs in performance—which traditional single-parameter testing fails to detect—and supports quality control across all stages, from R&D validation to mass production automation.

How to Choose a Leak Test Solution for Liquid-Cooled Plates? A Decision-Making Model Based on Three Factors: Leak Rate Requirements, Daily Production Volume, and Operating Costs

This article addresses the scenario of 100% inspection on production lines in the airtightness testing industry, emphasizing that repeatability is more critical than accuracy. Based on 11 consecutive sets of actual measurement data from the JCGK Direct-Pressure Airtightness Tester by Jingcheng Engineering, the study verifies that its leakage values remain stable at 6–7 Pa, with fluctuations of only ±1 Pa. The paper analyzes the three key technological pillars supporting this performance—high-precision sensors, proprietary gas path control, and temperature drift compensation algorithms—and concludes with recommendations for selecting the appropriate model for different pressure scenarios.

Q&A: Why Is Leak Tightness Testing the First Line of Defense for Reliability Against the Risk of Micro-Leaks in Data Center Liquid Cooling Systems?

This article analyzes the requirements for high-precision airtightness testing in liquid-cooling systems for AI data centers and points out that the risk of micro-leaks is a core threat to system reliability. Using the Shenzhen Jingcheng Engineering JC-C10005 differential pressure leak tester as an example, the article illustrates how domestically manufactured equipment—through flexible customization, rapid response, and cost advantages—is gradually replacing imported equipment. It has become a critical component in the initial inspection of liquid-cooling production lines and, in combination with helium leak testing, helps ensure the autonomy and controllability of the industrial chain.

Can Domestic Airtightness Testers Replace Imported Ones? A Guide to Selecting Equipment: From “Replacing Individual Machines” to “Reducing Costs and Improving Efficiency on Production Lines”

This article explains that the core rationale behind replacing imported equipment with domestically produced airtightness testers has shifted from “low-cost substitution” to “value surpassing.” Taking the Jingcheng Engineering JC-C10005 series as an example, domestically produced equipment has achieved parity with imported counterparts in terms of differential pressure measurement accuracy and has established differentiated advantages in areas such as automation integration, service response speed, and total cost of ownership. Currently, substitution is well established in mainstream mass-production scenarios such as new energy, automotive, and home appliances; only in extreme scenarios such as aerospace does a gap remain.

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.
