An article to read: why airtightness waterproof test equipment using gas test, rather than water test?

A common question asked by many manufacturing companies in the field of waterproofing and seal testing is:"Why is it now common for high-end testing equipment to use gas-tightness testing rather than direct water testing?"

This is not an accidental choice of technology, but a major upgrade of the precision manufacturing industry in the concept of quality control. As an industry leader in the field of airtightness testing for more than ten years, theJCGK will analyze the real logic of replacing water inspection with gas inspection through a professional point of view.The

Ⅰ. From the principle: gas detection is more sensitive and safer

The traditional soak test, while intuitive, suffers from two natural flaws:
firstlyLow detection accuracy, only obvious leaks can be found; and secondly, theDetection is destructiveOnce the product gets into the water, it is often scrapped.

And the Jingcheng Engineering Research and DevelopmentAirtightness TesterNon-destructive testing is carried out using gas as a medium through the principles of positive pressure method, negative pressure method, volumetric method, differential pressure method and flow method. Gas molecules are smaller and more permeable than liquids and can therefore beEarly detection of micro leakage defects, realizing "detecting air leakage before water leakage".The risk of waterproofing failure is avoided at the source.

Die casting airtightness solutions with Precision EngineeringDifferential Pressure InstrumentsAccuracy up to 0.1Pa, 0.001ml/min.

In high standard application scenarios(e.g. IP67/IP68 rating test)The sensitivity of the gas test can reach 0.1Pa level, which is unmatched by the water test.

II. In terms of efficiency and cost: gas detection is smarter and more economical

Water testing requires multiple steps such as water filling, drying, vacuuming, etc., which is not only time-consuming, but also increases equipment corrosion and secondary cleaning costs.
Instead, Precision Engineering's airtightness testing system uses theFully automated structurestogether withSmart Data AlgorithmsIt is also suitable for continuous operation in batch production lines, with faster inspection speeds and higher repeatability.

For example, JCGK's self-developedMulti-channel airtightness testing equipmentIt can test multiple parts at the same time within a few seconds, automatically determine whether they are qualified or not, and record the test data through the cloud to realize theFull life cycle quality traceabilityThe

In new energy, automotive electronics, medical devices and other fields, this type of inspection significantly improves production efficiency and consistency.

Ⅲ. From the product protection point of view: gas detection is more reliable and more in line with international standards

Water testing often leads to short circuiting of internal components or deformation of materials by water absorption.The risk is particularly high in products containing battery cells, sensors, and electronic component structures.

Precision Engineering's gas detection program utilizes non-contact detection.Zero damage to the product under test, accurate measurement of leakage and automatic conversion to waterproof grade.

Currently, JCGK equipment has passed CE certification and is widely used inNew energy vehicles, consumer electronics, water purification equipment, security lighting, medical equipmentand other high standard manufacturing industries. Its performance reaches or even exceeds the level of imported brands, but keeps thePrice advantage of localizationIt saves organizations a lot of money in testing and maintenance costs.
