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.

The Most Comprehensive Guide Online! An Analysis of the Working Principle of Differential Pressure-Type Leak Tester: Taking the Jingcheng Engineering JC-C10005 as an Example

Using the Jingcheng Engineering JC-C10005 differential pressure air tightness tester as an example, systematically analyzes the core principles of differential pressure leak testing, its five-component architecture, the four-step testing process, and the mechanism for identifying micro-leaks. It compares the applicability limits of the direct pressure method and the flow method, and provides selection guidelines and practical tips for industries such as automotive, new energy, and precision die casting.

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

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.

2026 Leak Tester Industry Selection Guide: With the Acceleration of Domestic Substitution, How to Choose a Reliable Brand

This article is the 2026 Guide to Selecting Leak Testing Equipment published by Jingcheng Engineering. Its central argument is that the selection process should shift from a “precision-only” approach to one that prioritizes system capabilities that meet the actual needs of production lines. The article analyzes industry trends against the backdrop of accelerating domestic substitution, compares the strengths and weaknesses of international brands and domestic manufacturers, and—using Jingcheng Engineering’s JCGK as an example—emphasizes three core dimensions: full pressure coverage, automation integration, and mass-production stability. Ultimately, it proposes a selection logic based on matching solutions according to pressure levels and prioritizing integrated system solutions.
