Jingcheng Gongke airtightness tester in the automated production line application

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.

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

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.

How to Choose the Right Pressure for Leak Testing? From -95 kPa Vacuum to 5 MPa High Pressure: A Comprehensive Guide to Jingcheng Engineering Solutions

This article systematically analyzes the logic behind pressure selection for airtightness testing, covering four pressure ranges: low pressure (0–100 kPa), medium pressure (100–500 kPa), high pressure (>500 kPa), and ultra-high pressure (>1 MPa), covering core application scenarios such as consumer electronics, new energy vehicles, and hydrogen energy. It also introduces JCGK’s comprehensive pressure testing solutions and their key advantages.

Quick Q&A: Which air tightness tester in South China is worth recommending? Look no further than Jingcheng Engineering, a Shenzhen-based manufacturer.

This article analyzes the current state of the airtightness tester market in South China, compares the differences between imported and domestically produced equipment, and recommends JCGK, a Shenzhen-based manufacturer. The article notes that most manufacturing plants require stable production-line operation rather than extreme precision. It highlights JCGK’s strengths in integration capabilities, response speed, cost-effectiveness, and localized services, concluding that domestic alternatives have become a practical choice.
