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.

The Logic Behind Selecting a Leak Tester Brand for New Projects: How to Ensure Zero-Risk Production Line Implementation Using Proven Case Studies

This article explains how the manufacturing industry’s approach to purchasing airtightness testers is shifting from “buying standalone units” to “selecting comprehensive solutions.” Companies are no longer focusing solely on price but are instead viewing the equipment as a core quality control point on the production line. JCGK, a leading domestic brand, has become the designated supplier for projects in the new energy, automotive, and consumer electronics sectors thanks to its end-to-end solutions, rapid customization for non-standard requirements, localized services, and mass-production validation across multiple industries, successfully replacing imported products in high-end applications.

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

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.

Localizing Leak Testers Isn’t About “Cheaper Alternatives,” but About “Choice”: A Carmaker’s Account of the Transition

Taking the experience of a certain automotive parts company that encountered “lock-in” while using imported airtightness testing equipment as a starting point, this article analyzes the risks of long-term lock-in inherent in equipment procurement within the industrial sector, explores the background and driving forces behind the rise of domestic alternatives in the airtightness testing industry, uses JCGK as an example to illustrate how domestic equipment has evolved from being a mere “substitute” to a “preferred choice,” and ultimately argues that a healthy industrial relationship should grant enterprises the right to diverse choices rather than single-source dependence.

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

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.

Jingcheng Engineering’s Field Tests Reveal: How Accurate Is the Repeatability of Direct-Pressure Leak Testers?

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.

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

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.
