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.

A leader in the air tightness testing industry

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

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?

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.

Air-tightness Tester for Food Packaging and Lunch Boxes

Precision Industrial Technology four-station automatic air tightness testing machine: food packaging lunch box sealing full inspection program review

This article reviews the Jingcheng Technology four-station automatic airtightness testing machine in the food packaging lunch box sealing the application of the full inspection. The article points out that sampling can not intercept the random distribution of sealing defects, the full inspection is the fundamental solution; through the actual test to verify that the equipment can be zero leakage judgment to identify trace leakage, and explains its independent four-channel, micro-pressure sensing and compensation algorithms, 72-hour stability verification of the three major technical support, as well as the production line adaptability and the head of customer cases.

From the Manhattan Project to Smart Manufacturing: A Look at the Past Life and Industrial Underpinnings of Airtightness Testers

This paper traces the evolution of airtightness testing technology from the birth of helium mass spectrometry leak detector of the Manhattan Project in 1943 to the present 80 years, analyzes the differentiation of pressure drop method, flow method and other technical routes, focuses on the waterproofing needs of smart phones and the development of new energy vehicles to promote the explosive growth of the industry, and points out that the Chinese manufacturers have been from the introduction of technology to the output of innovation, and the airtightness testing has become the invisible cornerstone of the quality control of the modern industry. It also pointed out that Chinese manufacturers have moved from technology import to innovation export, and airtightness testing has become the invisible cornerstone of modern industrial quality control.

Military-grade reliability and industrial-grade mass production at the same time! Uncovering the technological evolution of domestic airtightness testing solutions

This article takes the rescue incident of the U.S. military pilot's distress device as an entry point to reveal the core root cause of the failure of outdoor electronic equipment - sealing reliability rather than chip performance. The article systematically describes the technical principle of airtightness testing, the transformation of industry standards from sampling to full inspection, and the technical maturity path of domestic solutions (taking Jingcheng Industrial Technology as an example), emphasizing that airtightness testing is a key process to guard the reliability of equipment.

Airtightness tester selection guide: direct pressure, differential pressure, volumetric method of the essential differences and practical choice

This article introduces the working principle, applicable scenarios and selection decision logic of the three commonly used methods (direct pressure method, differential pressure method and volumetric method) of the airtightness tester. The direct pressure method is suitable for products with holes, low cost but limited stability; the differential pressure method eliminates interference through comparative measurements, with an accuracy of 0.1 Pa, which is suitable for high-precision micro-leakage detection; the volumetric method is specially designed for fully enclosed products with no openings to realize non-destructive sealing inspection. Selection should be based on a combination of product structure, accuracy requirements and production line schedule to avoid falling into common traps such as "low price is enough" or "ignoring the jig".

Q&A: Bought a high-precision airtightness meter but it's just for show? Be alert to the three major misunderstandings of automated production line integration

This paper points out the contradiction between the high-speed production of automated production lines and the traditional sampling mode, and emphasizes that the core value of on-line airtightness testing is to change the quality control from "probability game" to "certainty guarantee". It analyzes the three major misconceptions of the failure of enterprise deployment of equipment (stand-alone thinking, neglect of tooling design, data silos), and puts forward the key dimensions of technology selection, and finally illustrates the practical value of systematic integration with the case of Precision Industrial Technology.
