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.

Q&A: Is It Possible to Perform Leak Testing Without Custom Fixtures? A Comprehensive Guide to the Applications of Quick-Change Fixtures

2026-06-12

This article outlines strategies for selecting between quick-change fixtures and custom jigs for airtightness testing. Quick-change fixtures are suitable for scenarios such as prototype testing, small-batch trial production, and production line spot checks, offering advantages such as low cost, short lead times, and flexible changeovers; custom tooling, on the other hand, is better suited for high-volume mass production and products with complex structures. Both should be used in combination at different stages of the product lifecycle to achieve cost reduction and efficiency gains.
