In industries such as new energy, automotive parts, liquid cooling, consumer electronics, and medical devices,Air tightness testing equipment<\/a>We serve as the final line of defense in ensuring product integrity.When equipment isn't working properly, problems quickly surface on the production line.<\/strong>::Testing the same product three times yields three different results; minor leaks are missed; a single-channel delay holds up the entire production line; fixture mismatches cause false positives and missed detections to occur repeatedly; equipment cannot be integrated with the automated production line or the MES system; when a malfunction occurs, after-sales service takes more than three days to arrive.<\/strong><\/em>The<\/p>\n\n\n\n

You only realize the equipment isn\u2019t working well after you\u2019ve bought it, and replacing it takes both time and money. You\u2019re faced with a dilemma:Repair, upgrade, or switch to a different brand altogether?<\/strong><\/p>\n\n\n\n

Below, with reference to domestically produced...Airtightness Tester<\/a>ManufacturerShenzhen Jingchenggongke Technology Co., Ltd.<\/a>(JCGK)\u2019s industry application experience, explained through six questions.<\/p>\n\n\n\n

Q1:Air tightness testing equipment<\/a>If it doesn't work well, do I have to switch brands?<\/h2>\n\n\n\n

Not necessarily. Let's figure out the cause first, then decide whether to replace it.<\/strong>The<\/p>\n\n\n\n

Leak testing is a systematic process. The results depend not only on the instrument but also on the product\u2019s structure, the fit of the test fixture, the test pressure, the filling time, the equilibration time, the test duration, and the ambient temperature. If any one of these factors goes wrong, the instrument will take the blame.<\/p>\n\n\n\n

On-site Issues<\/th>Common Causes<\/th>Areas for Optimization<\/th><\/tr><\/thead>
Poor repeatability<\/td>Product elastic deformation, temperature fluctuations, and fixture instability<\/td>Optimize the testing process and adjust the compensation parameters<\/td><\/tr>
High false positive rate<\/td>Poor assembly sealing; unreasonable test parameters<\/td>Inspection Fixtures and Test Conditions<\/td><\/tr>
Inaccurate micro-leak detection<\/td>The instrument's accuracy or detection principle is not compatible with the product<\/td>Reevaluate the Testing Protocol<\/td><\/tr>
Slow test speed<\/td>Excessively long detection time and insufficient single-channel efficiency<\/td>Optimize the takt time or add lanes<\/td><\/tr>
Data cannot be traced<\/td>System Functionality Mismatch<\/td>Add data export or MES integration<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

If the issue can be resolved through adjustments to parameters and tooling, there is no need to replace the equipment.Since the equipment\u2019s core testing capabilities fall short of product requirements and the original manufacturer cannot provide an effective upgrade solution, switching to a different brand is the only viable option.<\/strong><\/p>\n\n\n\n

Q2: ReplacementAirtightness Tester<\/a>, what should be the main focus?<\/h2>\n\n\n\n

Don't just look at the price, and don't just look at the specs on the brochure.<\/strong>. The following five items are listed in order of importance.<\/p>\n\n\n\n

1. Measurement Accuracy and Repeatability<\/h3>\n\n\n\n

This isAirtightness Tester<\/a>The most critical metric. It\u2019s not enough to look at the minimum resolution; you need to examine the performance in repeated tests under actual operating conditions.<\/p>\n\n\n\n
