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.

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.

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.
