Jingcheng Engineering Secures Three More Software Copyrights: How Did the Airtightness Tester Evolve from a “Standalone Instrument” to an “Intelligent Production Line System”?

August 19, 2026,Shenzhen Jingchenggongke Technology Co., Ltd.(Abbreviation: Jingcheng Engineering, JCGK) has obtained three computer software copyright registrations, each related toAutomated production line control, comprehensive testing of seals for airtightness and pressure resistance, and testing of chamber airflow resistance and pressure resistance limitsExpand. It's not as simple as just three software names.

I. Buy oneAirtightness Tester, What are you really buying?

ProcurementAir Tightness Tester EquipmentWhen making a purchase, many companies first look at the pressure range, detection accuracy, leak resolution, and price. These parameters are certainly important,But they're only concerned with one thing: whether the equipment can take measurements.The

For the manufacturing industry, aAir tightness testerOn the mass production floor, simply displaying "OK" or "NG" is no longer enough.

Engineers on the production line are concerned with a different set of issues:Can the equipment be integrated into the production line? Can the test results trigger the PLC to execute the next step? Can the data be saved? How should the program be adjusted when switching between different product models? Can test items such as airtightness, pressure resistance, and airflow resistance be integrated into a single system to form a comprehensive quality assessment?The

These questions can no longer be answered by hardware specifications alone.They test software, algorithms, and automation integration capabilities.The

II. Three Software Copyrights, Three Directions

The three software products registered by Jingcheng Engineering (JCGK) correspond to three different capability dimensions in industrial inspection scenarios.

Automated Control Software for Integrated Air Leak Testing on Assembly Lines V1.0

Software Copyright Registration No. 18062045

The keyword for this software is "Interconnection".

A typical automated airtightness testing station follows this process:Product in place → Fixture clamped → Instrument starts inspection → Outputs OK/NG → PLC executes the next step. For production line engineers, a “OK"It doesn't mean much,"What really matters is whether this assessment result can become part of the control logic for the entire production line.

Products marked as "NG" must be automatically intercepted and cannot proceed to the next stage; products marked as "OK" automatically move on to the next process; data is simultaneously written to the MES system for traceability.. This line of reasoning is “Interconnection"The real issue that needs to be addressed."

Comprehensive Calibration Software for Air Tightness and Pressure Resistance of Seal Assemblies V1.0

Software Copyright Registration No. 18062037

"No leaks" does not mean "reliable"The

For products such as seals, valve bodies, piping, and chambers, actual testing often requires simultaneous evaluation of airtightness, pressure resistance, performance under various pressure conditions, and compliance with established quality criteria. Conducting a single airtightness test can only answer “Does it leak or not?", cannot answer "Will it hold up under extreme conditions?".

"Comprehensive airtightness and pressure resistance testing" corresponds to a more comprehensive quality verification process.—Moving from single-factor testing to multidimensional performance evaluation.

Software for Testing Cavity Ventilation Resistance and Pressure Resistance Limits, V1.0

Software Copyright Registration No. 18061838

The challenge in testing some products does not lie in “Does it leak or not?", but rather in "How is the airflow?".

A component with an internal cavity and air passage structure may, even if it shows no obvious leaks overall, still suffer from abnormal resistance in its internal passages, insufficient airflow capacity, or localized blockages. For such products, it is also necessary to know their pressure limits—a factor that directly affects safety design.

Airflow resistance and pressure tolerance are another aspect of testing., and it's also ordinaryAir tightness testerRequirements that cannot be fully covered.

III. A Combined Look at the Three Software Copyrights

hardware	Key Focus Areas	Problems Solved
Automated Control Software for Integrated Leak Testing on Assembly Lines	Production Line Integration and Automated Control	From Standalone Testing to Production Line Integration
Comprehensive Calibration Software for Airtightness and Pressure Resistance of Seal Assemblies	Comprehensive Leak and Pressure Resistance Validation	From Individual Testing to Comprehensive Quality Assessment
Software for Testing Cavity Ventilation Resistance and Pressure Resistance Limits	Ventilation Performance and Pressure Resistance Limits	Address more complex performance testing requirements

Taken together, these three areas describe the same thing:Air tightness testing equipmentIt is evolving from "instruments" to "testing systems."

IV. Why is this important for Jingcheng Engineering’s brand development?

This is because brand competition is shifting from a "race in hardware specifications" to a "competition in comprehensive engineering capabilities."

Past PurchasesAirtightness Tester, the main points of comparison might be:

What is the pressure range?

What is the accuracy?

What is the leak resolution?

How much does it cost?

Now that we’ve moved to an automated production line, the procurement team and engineers are still asking:

Can you provide custom solutions?

Can it be connected to a PLC?

Can it be integrated with a robotic arm?

Can it integrate with MES?

Can the data be traced?

Can multiple devices be managed centrally?

How should the program be adjusted after switching products?

These issues, in essence, go beyond the scope of mere hardware specifications.

It puts a company to the testManufacturers of Leak Testing EquipmentR&D capabilities, software algorithms, automation, tooling and fixtures, and engineering services.

The successful approval of these three software copyright registrations—at least as reflected in the publicly available certificates regarding their intellectual property portfolio—indicates that the company is continuing to increase its investment in research and development, and that a large number of patents are currently pending.

Conclusion

There is a practical rule in the industrial inspection industry.

Whether the equipment specifications are good enough determines whether a measurement can be taken.
The reliability of the software and algorithms determines whether stable testing is possible.
Whether or not automation capabilities are in place determines whether a product can be incorporated into the production line.
Whether engineering services can keep up will determine whether the system can operate in the long term.

In the past, many efforts to replace imported products with domestic alternatives stalled at the very first step.Meets specifications and is more affordable...That's enough. But for domestic substitution to truly mature, it must also address the following questions.

JCGK has previously covered a variety of airtightness testing solutions, including differential pressure, direct pressure, flow-based, and positive displacement methods....used in industrial applications such as new energy, automotive components, home appliances, consumer electronics, medical devices, security and lighting, robotics, aerospace and defense, and liquid-cooled heat dissipation. The fact that they have obtained three software copyrights this time demonstrates that theyWe are also continuing to focus our efforts on automated control, comprehensive verification, and specialized performance testing.The

For companies currently building automated inspection production lines, there is a more direct way to determine whether a supplier is worth a long-term partnership.

"Ask him straight out: 'Are you selling me a piece of equipment, or a testing solution that can grow alongside the production line?'"
