Q&A: Why are more and more overseas customers choosing China's domestic airtightness testing brands?

This article analyzes the reasons why domestic airtightness testing equipment (JCGK, for example) is favored by overseas customers: changes in the overseas manufacturing environment have made it necessary for emerging production areas to meet the quality standards of developed countries, and remote monitoring relies on stable data. Chinese manufacturers have completed three major transformations - from "parameter-driven" to "engineering-driven", from "selling equipment" to "delivering inspection solutions", and from "price advantage" to "system advantage" - to provide complete inspection capabilities that are quickly deployed, low misjudgment rate, and easy to operate, and ultimately break the monopoly of knowledge and realize the export of quality methodology and engineering capabilities.

Global industry chain reconstruction: China's airtightness testing enterprise's role changes and the path of overseas broken circle

This paper introduces the role change of Chinese airtightness testing enterprises under the reconstruction of the global industrial chain. From equipment supplier to quality solution provider to standard setter, Shenzhen Jingcheng Industrial Technology Co., Ltd. is deeply involved in production line planning, transforming the cost-effective advantage into system advantage, and outputting cognition and technology. Industrial differentiation, quality capability exporters, standard participants, customer process optimization partners will exist for a long time.

The final line of defence in the safety valve engineering system

QUICK QUESTION: Why must safety valves be tested for opening pressure, flow rate, and airtightness (watertightness)?

This article describes the importance of the three core items of safety valve testing: opening pressure, flow characteristics and gas (water) tightness. The opening pressure determines when the safety valve opens, the flow characteristics affect the pressure relief efficiency, and the airtightness test ensures daily reliability. Precision Engineering provides multi-channel test equipment to realize the leap from experimental verification to mass production quality inspection, and its testing program forms a complete logical closed loop, applicable to new energy, energy storage systems and other demanding fields.
