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

2026-06-18

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.

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

2026-06-12

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.

Quick Q&A: What’s the Difference Between Differential Pressure and Flow-Type Leak Detectors? Everything You Need to Know in One Article—Don’t Make the Wrong Choice Again

2026-05-29

This article systematically compares the key differences between differential pressure-type and flow-type airtightness testers. Differential pressure-type testers detect micro-leaks by comparing pressure changes between the test specimen and a standard reference chamber. They are resistant to temperature drift, offer high accuracy, and provide excellent repeatability, making them suitable for applications with high sealing requirements, such as new energy battery packs and automotive electronics; Flow-type testers directly measure the volume of gas leaked per unit time. They excel at identifying large leaks, measuring gas flow rates, and detecting blockages, making them suitable for flow performance analysis of valves, nozzles, and permeable membranes. The two types are not ranked as superior or inferior; rather, the choice depends on whether the testing objective is to determine "leakage" or "gas flow."

Quick Q&A: Why do distributors prefer to partner with Jingcheng Engineering, a direct manufacturer of airtightness testers?

2026-05-22

This article uses a Q&A format to analyze why JCGK, a leading manufacturer of airtightness testing equipment, has adopted a dual-track approach combining "in-house R&D" with "channel partnerships." The article notes that due to the geographically dispersed nature of the industrial equipment market and the high demands for service responsiveness, technology-driven manufacturers must rely on intermediaries to provide localized services. JCGK exports its core technologies through an ODM model, while intermediaries cover regional markets under their own brands, thereby achieving a specialized division of labor between technical capabilities and service capabilities.

Jingcheng Gongke airtightness tester in the automated production line application

Quick question and answer: What makes the domestic source manufacturer Jingcheng Gongke's airtightness instrument can replace the imported brand?

2026-05-15

This paper objectively analyzes the domestic airtightness testing equipment to replace the feasibility of imported brands, pointing out that in the mainstream industrial scene of 90% China's domestic production already has the strength of the level of replacement, but there is still a gap in the extreme high-precision areas. Take the national brand Jingcheng Gongke JCGK as an example, emphasizing that the core of "equal replacement" is the ability to land a complete set of solutions rather than low price competition.
