In precision manufacturing, gas tightness testing is an important step in ensuring product quality and safety.
As a veteran engineer in the manufacturing industry for more than 20 years, I have witnessed three major innovations in product airtightness testing technology.From the initial manual water inspection, to single-station airtightness testing, to the current multi-channel intelligent inspection system, with each advancement I am struck by how fast technology is evolving. Let's start by reviewing this technological evolution.
I. Evolution of airtightness testing methods
I remember when I first joined the industry, the workshop was still clear of manual water inspection. Workers needed to put the products into the pool, and one by one, they would observe with their eyes whether there were bubbles coming out. To be honest, it was really hard and inaccurate at that time.
To help you visualize the change, I've put together a comparison table:
| Comparison Program | Artificial soaking airtightness test | Automated Airtightness Testing |
| Detection efficiency | Detection time per piece approx. 30-60 seconds | Detection time for a single piece approx. 10-15 seconds (2 pieces can be detected at the same time with dual channels) |
| Personnel requirements | 2-3 skilled workers required | 1 operator is sufficient |
| Detection accuracy | Dependent on human eye observation with limited accuracy | Detects small leaks (down to 0.1 Pa) |
| consistency | Highly affected by the state of personnel | Stable and reliable with good consistency |
| Testing costs | High water consumption and high labor costs | Low running costs due to compressed air only |
| environmental | Wastewater treatment issues | Non-polluting, more environmentally friendly |
| Data traceability | Difficult to record and trace | Automatic logging and support for MES system interfacing |
| Site requirements | Requires a dedicated waterproof area | Ordinary workshops are sufficient |
| working environment | Moist and prone to rust | Clean and dry |
| quality control | Subjective judgment prevails | Objective data-based |
| investment cost | Low upfront investment | Higher upfront investment |
| Long-term gains | High operating costs | Low operating costs and fast payback |
Seeing this table reminded me of a very interesting case the other day.
There's a customer who makes car cameras.Originally, with the traditional water inspection, it takes 6 people just to inspect every day, and there are often missed inspections. Since the change of our dual-channel airtightness testing equipment, now 1 person can complete more workload, the detection accuracy has been improved, the defective rate dropped directly by 30%.

You see, this is the benefit of automation. Although the owner may feel expensive when buying the equipment, it won't take long to make the cost back!
II. Introduction to automated testing equipment
Speaking of our protagonist today - dual-channel floor-standing airtightness testing equipment, which is the work of our Jingcheng Industrial Technology has condensed many years of experience.
1. Core strengths:
- Dual channel simultaneous detection, double the efficiency
- Highly accurate sensors for precise capture of micro leaks
- Intelligent operation interface with one-button start
- Dual-screen display (device screen + industrial controller), intuitive results
2. Intelligent upgrading:
- Reserved MES (Manufacturing Execution System) interface
- Support for data acquisition and analysis
- Production traceability is possible
- Automatic optimization of parameters
3. Practical applications:
Take automotive camera inspection as an example
- Detection pressure: 150kPa
- Specialized jigs and fixtures for positioning
- Fully automated inspection process
- Real-time data display
III. Recommendations for use
As an engineer, I would suggest that care be taken when using it:
- Regular calibration of equipment
- Keep workholding fixtures clean
- Regular inspection of the air circuit system
- Good maintenance of equipment
Even the best equipment requires professional operation and maintenance.
IV. Areas of application
This device is widely used:
- Automotive accessories: e.g. in-car cameras, panoramic image systems
- Consumer electronics: all types of electronic parts that need to be sealed
- Medical devices: medical devices requiring air tightness
- Other products that need to be tested for leak tightness
V. Future prospects
Looking to the future, Jingcheng Gongke airtightness testing equipment will also develop in the direction of smarter and more accurate:
- AI Intelligent Recognition
- IoT Integration
- Predictive maintenance
- Higher Precision Detection
Summarize
In my personal experience, Jingcheng Engineering can stand firm in the field of airtightness testing, relying not only on excellent technology, but more importantly, the persistent pursuit of product quality.I remember a customer said, "Choosing Precision Engineering is choosing peace of mind." This quote is particularly apt.
