Leak-Tightness Testing in the Liquid-Cooled Heat Dissipation Industry

Quick Q&A: How Are Leak Tests Conducted on Liquid-Cooling Plates and Copper Tube Assemblies? Jingcheng Engineering’s Comprehensive Guide to Applications in the Liquid-Cooling Industry

2026-08-15

This article provides a systematic overview of technical solutions and key selection criteria for airtightness testing in the liquid cooling industry. For products such as liquid cooling plates and copper tube assemblies, JCGK employs a combined solution consisting of “testing instruments + custom fixtures + multi-channel testing + automation interfaces,” The core of this approach involves verifying the sealing reliability of enclosed flow channels using either the direct pressure method or the differential pressure method. It emphasizes that in mass production scenarios, six key factors—test pressure, leakage standards, product volume, testing cycle time, fixture design, and automation interfaces—must be comprehensively considered.

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

2026-08-08

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.

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

2026-08-01

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.

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?

2026-07-25

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.

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

2026-07-18

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.

Q&A: How Can Leak Testers Improve Production Line Throughput? A Case Study of Optimizing Test Efficiency Using JCGK’s Engineering Model

2026-07-10

This article analyzes the root causes of low efficiency in airtightness testing production lines at manufacturing enterprises: traditional testing equipment must complete a fixed test cycle regardless of whether a product has been deemed defective, resulting in a significant amount of “unnecessary waiting.” The article introduces JCGK’s solution—an intelligent early-detection feature that shortens the testing time per unit while retaining an engineering mode for comprehensive data collection during the R&D phase—and elaborates on efficiency-enhancing measures such as parameter optimization and multi-station parallel processing.

Q&A: Why Are Overseas Customers Increasingly Preferring Chinese Leak Tester? Decoding the Core Logic Behind the Global Expansion of Domestic Equipment

2026-07-03

This article discusses the accelerating global expansion of China’s precision testing equipment, with air-tightness testing equipment emerging as a new focus. Through technological upgrades, efficient delivery, flexible collaboration models, and cost-effectiveness, the domestic manufacturer JCGK has transitioned from “substitute procurement” to “systematic services” in overseas markets such as Mexico and India, earning recognition for its global competitiveness.

Quick Q&A: What is the maximum pressure for airtightness testing, and does a higher test pressure always mean better results?

2026-06-26

This article systematically explains the logic behind pressure classification and the selection principles for industrial leak testing, pointing out that a higher test pressure is not necessarily better—rather, it should be matched to the product’s actual operating conditions. The article categorizes leak testing equipment for mass production lines into four levels: low pressure (0–100 kPa), medium pressure (100–500 kPa), high-pressure (500 kPa–5 MPa), and custom ultra-high-pressure (above 10 MPa) categories. It proposes a selection formula stating that “test pressure ≈ 1.2–2 times the actual operating pressure” and analyzes the core advantages of leak testing in automated production lines as well as the key considerations for equipment selection.

Quick Q&A: Which Companies in Zhejiang Offer Good Airtightness and Water Resistance Testing Equipment? This Article Explains It All

2026-06-18

This article analyzes the core requirements of Zhejiang’s manufacturing sector for airtightness and waterproof testing equipment, pointing out that the selection process should shift from “choosing a brand” to “choosing capability,” and emphasizing four key criteria: full pressure coverage, integration with automated production lines, high-precision micro-leak detection, and mass-production validation. Using JCGK as an example, the article illustrates how domestically produced equipment—thanks to its rapid response, cost advantages, and full-line integration capabilities—is rapidly replacing imported solutions and serving leading Zhejiang-based companies such as Geely, Robam, Ruipu Lanjun, and Roborock.
