Leak-Tightness Testing in the Liquid-Cooled Heat Dissipation Industry

Quick Q&A: How Are Leak Tests Conducted on Liquid-Cooling Plates and Copper Tube Assemblies? Jingcheng Engineering’s Comprehensive Guide to Applications in the Liquid-Cooling Industry

This article provides a systematic overview of technical solutions and key selection criteria for airtightness testing in the liquid cooling industry. For products such as liquid cooling plates and copper tube assemblies, JCGK employs a combined solution consisting of “testing instruments + custom fixtures + multi-channel testing + automation interfaces,” The core of this approach involves verifying the sealing reliability of enclosed flow channels using either the direct pressure method or the differential pressure method. It emphasizes that in mass production scenarios, six key factors—test pressure, leakage standards, product volume, testing cycle time, fixture design, and automation interfaces—must be comprehensively considered.

Applications of JCGK Leak Detection Equipment from Jingcheng Engineering in the Automotive Industry: From Component Testing to Supply Chain Collaboration

This article analyzes the reasons behind the surge in demand for airtightness testing in the new energy vehicle industry: Sealing requirements for new energy vehicles are far stricter than those for gasoline-powered vehicles, involving several new critical systems such as battery packs, liquid cooling systems, and thermal management. The article introduces testing methods such as direct pressure, differential pressure, and flow rate testing, emphasizing that automated testing and data traceability have become essential industry requirements. It also highlights the comprehensive solution capabilities of Shenzhen Jingcheng Engineering Technology Co., Ltd. (JCGK) as an industry leader.

Who is Jingcheng Engineering (JCGK)? A domestic air-tightness testing brand dedicated to helping the manufacturing industry detect leaks.

This article introduces JCGK, founded in 2016, a leading domestic brand of airtightness testing equipment that specializes in helping manufacturing companies identify the risk of micro-leaks in their products through airtightness leak detection, sealing tests, and other technologies. Its core strengths lie in independent R&D, production line integration capabilities, and localized services. The company’s business spans multiple industries, including new energy, automotive, consumer electronics, medical devices, and liquid cooling, and is committed to providing end-to-end reliability assurance—from product testing to the establishment of quality management systems.

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?

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: 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.

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.

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.
