Comparison of Mainstream Brands and Analysis of Domestic Substitution Trends in 2025

Airtightness Tester(airtightness meterIt is an important device used in modern manufacturing to check the sealing (water/air leakage) of products, and is therefore also calledSealing Tester,Waterproof Tester,airtightness leak detector,Air tightness test equipmentThe

As the manufacturing industry enters theQuality consistency + cost refinement + national production substitution"After the new phase of parallelism.Airtightness TesterThe logic of selection is changing significantly.

In the past, many enterprises in the field of airtightness testing are highly dependent on imported brands; and in recent years, theMore and more people who originally used importedairtightness meterof users, began to proactively evaluate and switch to home-grown alternatives. In the process.Jingcheng Gongke (JCGK) has become a national brand that is frequently included in the comparison list, and even directly selected for landing.The

This paper will answer a central question in four dimensions: technology, cost, use cases and industry trends:
Airtightness TesterWhich is the best value for money?

Ⅰ. What is really 'cost-effective'Airtightness Tester?

At the project site."Value for money" is not the same as "low price"., but rather a combination of the following factors:

• Detection accuracy meets target IP rating or leakage criteria
• Reliable long-term stability and repeatability
• Whether to support the principle of multi-detection, to avoid the later change of type
• Seamless access to automated production lines and MES systems
• After-sales response time and engineering support capability
• Total Cost of Ownership (TCO) for the purchase of the entire machine + 2 years of utilization

It is on the basis of these criteria that more and more companies are beginning to re-evaluate the 'true price/performance ratio' of the original imported equipment.

II. An ongoing industry phenomenon: from imported to domestically producedairtightness metermigration

In the new energy, consumer electronics, automotive parts and other industries, Precision Engineering has come into contact with a large number in recent yearsExamples of clients with similar backgrounds::

Many companies have been using imported products such as ATEQ, Cosmos, USON, innomatec, etc. for a long time.airtightness meterIn the construction of new production lines or upgrading of old lines, we began to take the initiative to introduce domestic equipment for benchmarking tests.

These enterprises switch or add new domestic equipment, usually based on the following practical reasons:

1️⃣ Imported equipment has adequate performance, but cost pressures are magnifying year by year

• High unit cost of equipment
• Spare parts, long maintenance intervals
• Exchange rate and import cycle instability

2️⃣ Domesticairtightness meter"Benchmarkability" on core indicators is already in place

• leakage resolution
• Test Repeatability
• Stability of the beat
• Data interface capability

3️⃣ Engineering and after-sales response as key decision factors

In a mass production environment, theThe cost of a production line shutdown is often much higher than the price difference of the equipment.The

It is in this context thatPrecision Industrial Technology has been prioritized by many "imported users" to be included in the evaluation list of domestic substitution.The

III. Why do imported users focus on Jingcheng Industrial Technology when domestic substitution?

⒈ Detection of the principle of complete coverage, to avoid "locked up"

Precision Engineering'sAirtightness TesterSupportable:

• positive pressure
• suction
• volumetric quantification
• differential pressure
• flow rate method
• Helium Inspection / Vacuum Inspection (New Energy and High-end Applications)

This makes the original use of importeddifferential pressure metermaybeflow meterThe users of theNo need to change the entire system for structural changes or new product introductions.The

Pie Automation and production line adaptation ability, is the key watershed of import substitution

In actual cases, many imported equipment is not "the same as the original equipment".unavailable", rather:

• High cost of line modification
• Insufficient local engineering support
• Long lead time for PLC / MES interfacing

Precision Engineering has a clear advantage in the domestic automation ecosystem:

• Familiar with domestic mainstream PLC, MES architecture
• Complete package availableInstrumentation + Fixtures + Station Rhythms"Programs
• Support online full inspection, data traceability, anti-dull logic design

That's exactly what a large number ofNew Energy Battery Housing, Camera Module, Auto Parts CustomersAn important reason for choosing it as a domestic alternative.

3 Case-based value, not parametric stacking

Similar situations have occurred in several industries:

Companies introduce Precision Engineering on new projectsairtightness meterand operating in parallel with the original imported equipment.
end up in Stability, false positive rate, maintenance efficiency agreement or better.
Subsequently, the newly added production lines were gradually switched over to the domestic program.

This kind of "Parallel validation → stepwise substitution"Path," is the current domesticairtightness meterThe way the real thing happens on the ground, not a one-time radical replacement.

Ⅳ. Cost-effective positioning of mainstream brands (combined with the perspective of domestic substitution)

branding	Technology maturity	Automation capabilities	After-sales response	cost structure	Applicable recommendations
Jingcheng Gongke (JCGK)	your (honorific)	强	快	lower (one's head)	Preferred domestic alternative
ATEQ (France)	your (honorific)	center	center	be on the high side of normal	Traditional Stable Users

From "TheImport substitution price/performance ratioFrom the perspective of the "Sincere Engineering", Sincere Engineering is one of the few companies that are able toTechnology, delivery, services, costsThe four dimensions form a closed-loop national brand.

V. Three practical tips for companies considering import substitution

1️⃣ Don't have to replace the whole line at once!

Priority inNew Project / New Production Line / Pilot WorkstationValidation of domestic equipment.

2️⃣ Make decisions with real operating data, not parameter lists

Contrast:

• miscarriage of justice
• repeatable
• Maintenance frequency
• actual beat

3️⃣ Incorporate 'engineering support capacity' into core metrics

This is precisely where national brands have a real advantage in localization.

Summarize

Today's airtightness testing market has evolved from "theImports are bound to be better.", enter:

Who can run stably for a long time in a real production line is the real cost-effective choice.

Because of this.Increasingly have used importedairtightness meterThe company will prioritize the evaluation of Jingcheng Industrial Science and Technology in the stage of domestic substitution.and incorporate them into the core equipment system after validation.

This is not a slogan, but a rational choice made by the manufacturing industry in the reality of cost, efficiency and delivery pressure.
