As an engineer who has been traveling around the production line of factories for many years, I know that the quality of a product's airtightness often directly determines the product's quality fate.<br><strong>How exactly do you quickly and accurately determine if a product is leaking in a busy production process?<\/strong>\u00a0Let's talk about this seemingly simple but highly specialized topic today.<\/p>\n\n\n\n<h2 class=\"wp-block-heading cheese-cake\" style=\"margin-top:var(--wp--preset--spacing--70)\">I.

Apply soapy water to the suspected leak, and if bubbles are produced, it is undoubtedly 'running'. This method is low-cost, easy to operate, and suitable for quick on-site judgment, but has limited accuracy and can only detect more obvious leaks.<\/li>\n\n\n\n<li><strong>Underwater detection method:<\/strong>\u00a0Immerse the inflated and pressurized product in water and watch carefully for air bubbles escaping from the surface of the product. This method is more intuitive than soap and water, but the operation is relatively cumbersome, and does not apply to electronic products that can not touch water or other parts that are afraid of water.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1000\" height=\"666\" src=\"https:\/\/www.air-tester.com\/wp-content\/uploads\/2025\/04\/rou-yan-ke-jian-de-jian-ce-fa.jpg\"  class=\"wp-image-6547\" style=\"width:1200px;height:auto\" srcset=\"https:\/\/www.air-tester.com\/wp-content\/uploads\/2025\/04\/rou-yan-ke-jian-de-jian-ce-fa.jpg 1000w, https:\/\/www.air-tester.com\/wp-content\/uploads\/2025\/04\/rou-yan-ke-jian-de-jian-ce-fa-18x12.jpg 18w, https:\/\/www.air-tester.com\/wp-content\/uploads\/2025\/04\/rou-yan-ke-jian-de-jian-ce-fa-600x400.jpg 600w\" sizes=\"(max-width: 1000px) 100vw, 1000px\" title=\"\u4ea7\u54c1\u6f0f\u6c14\u600e\u4e48\u529e\uff1f\u80a5\u7682\u6c34\u3001\u6c34\u68c0\u6cd5\u3001\u6c14\u5bc6\u4eea\u3001\u6c26\u68c0\u4eea\uff0c\u591a\u7ef4\u65b9\u6848\u8be6\u89e3\u63d2\u56fe\" alt=\"\u4ea7\u54c1\u6f0f\u6c14\u600e\u4e48\u529e\uff1f\u80a5\u7682\u6c34\u3001\u6c34\u68c0\u6cd5\u3001\u6c14\u5bc6\u4eea\u3001\u6c26\u68c0\u4eea\uff0c\u591a\u7ef4\u65b9\u6848\u8be6\u89e3\u63d2\u56fe\" \/><figcaption class=\"wp-element-caption\"><em>Naked eye visible detection method: rely on manual naked eye observation, limited accuracy<\/em><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Professional-grade precision testing<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong><a href=\"http:\/\/www.air-tester.com\/en\/\" data-type=\"link\" data-id=\"www.air-tester.com\" target=\"_blank\" rel=\"noreferrer noopener\">airtightness meter<\/a>Testing:<\/strong>\u00a0<strong>Use of professional<a href=\"http:\/\/www.air-tester.com\/en\/\" data-type=\"link\" data-id=\"www.air-tester.com\" target=\"_blank\" rel=\"noreferrer noopener\">Airtightness Test Equipment<\/a>The test equipment, such as direct pressure, flow or differential pressure test equipment.<\/strong>These \"pros\" give quantitative leakage data with much greater accuracy and reliability.

From qualitative to quantitative: scientific judgment of airtightness<\/h2>\n\n\n\n<p>In the past, airtightness testing often relied on experienced masters to judge 'by feel'. However, in the contemporary precision manufacturing environment, this is not enough.<br><strong>At Precision Engineering's<a href=\"http:\/\/www.air-tester.com\/en\/\" data-type=\"link\" data-id=\"www.air-tester.com\" target=\"_blank\" rel=\"noreferrer noopener\">Air tightness tester<\/a>We have established a complete automated testing process by setting specific test pressure and leakage pressure criteria.<\/strong>\u00a0The standard of judgment has also changed from the vague 'doesn't look like it's leaking' to a precise comparison of values - the<strong>If the leakage value in the test result is below the set leakage pressure standard, then the airtightness can be considered good; if the leakage value exceeds the standard, then it indicates that there is an air leakage problem.<\/strong><\/p>\n\n\n\n<iframe src=\"\/\/player.bilibili.com\/player.html?isOutside=true&#038;aid=1504340489&#038;bvid=BV1dD421P7y1&#038;cid=1539382025&#038;p=1&#038;autoplay=1\" scrolling=\"no\" border=\"0\" frameborder=\"no\" framespacing=\"0\" allowfullscreen=\"true\" style=\"width:100%;aspect-ratio:16\/9;\"> <\/iframe>\n\n\n\n<p style=\"font-size:15px\"><em>Precision Engineering<a href=\"http:\/\/www.air-tester.com\/en\/\" data-type=\"link\" data-id=\"www.air-tester.com\" target=\"_blank\" rel=\"noreferrer noopener\">Airtightness Tester<\/a>: Display of specific leakage values for micro, medium and large leaks<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading cheese-cake\" style=\"margin-top:var(--wp--preset--spacing--70)\">III. Controversies within and outside the industry: how strict is strict enough?<\/h2>\n\n\n\n<p>It is interesting to note that different industries have very different standards on the question of 'what level of leakage counts as an air leak':<br><em>While the appliance industry may accept leakage rates of a few milliliters per minute, in semiconductor manufacturing, leakage rates of more than 0.11 TP3T per year may be considered catastrophic failures.<br><\/em><\/p>\n\n\n\n<p>Experienced engineers at Precision Engineering often say, \"The<strong>There is no such thing as a system that absolutely does not leak, only a system that leaks acceptably.<\/strong>\"This statement speaks to the philosophy at the heart of airtightness testing - the<strong>What we need is not an absolute seal, but a sealing performance that meets the needs of a specific application.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading cheese-cake\" style=\"margin-top:var(--wp--preset--spacing--70)\">IV. From problem to solution: what to do after a leak?<\/h2>\n\n\n\n<p>Finding a leak is only the first step, solving the problem is the ultimate goal. According to Precision Engineering's years of industry experience, common causes of leaks include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Material aging or deformation<\/li>\n\n\n\n<li>Uneven sealing surface<\/li>\n\n\n\n<li>Stress concentrations due to improper installation<\/li>\n\n\n\n<li>Uneven bolt torque<\/li>\n\n\n\n<li>Improper seal selection<\/li>\n<\/ul>\n\n\n\n<p>The solutions to these problems vary. Sometimes a simple replacement of an O-ring will solve the problem, other times the entire sealing system needs to be redesigned.<strong>We, Jingcheng Industrial Technology, not only provide testing equipment, but also provide customers with systematic sealing solutions, from material selection to structural optimization, all-round protection of product airtight performance.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading cheese-cake\" style=\"margin-top:var(--wp--preset--spacing--70)\">V. Back to Basics: The Future Development of Airtightness Testing<\/h2>\n\n\n\n<p>With the advancement of Industry 4.0, airtightness testing is also developing in the direction of intelligence and networking. We see more and more companies are adopting online monitoring systems to realize real-time airtightness monitoring during the production process; artificial intelligence algorithms have also been introduced into the analysis system, capable of predicting potential leakage risks.<br>But no matter how the technology evolves, the essence of airtightness testing remains to ensure product performance and safety.<strong>From simple soapy water tests to complex helium detection systems, we pursue the same goal - to make our products more reliable and our users more at ease.<\/strong><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Summarize<\/h2>\n\n\n\n<p>As an engineer, I have always believed that<strong>The best airtight design is the one that is just right \"neither over nor under\".<\/strong>\u00a0After all, over-design means cost waste, and under-design means quality risk. In this age of excellence, finding this balance may be just what we are all striving for.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p style=\"font-size:15px\">For any airtightness or watertightness testing needs, welcome to visit Jingcheng Engineering's airtightness website or feel free to contact us, we will be happy to serve you!<\/p>\n<\/blockquote>\n\n\n\n<p><em><strong>Original Statement:<\/strong>&nbsp;this paper was written by<a href=\"http:\/\/www.air-tester.com\/en\/\" data-type=\"link\" data-id=\"www.air-tester.com\" target=\"_blank\" rel=\"noreferrer noopener\">Shenzhen Jingchenggongke Technology Co., Ltd.<\/a>Written by the technical team, reproduced with attribution.<strong>Data sources:<\/strong>Precision Engineering internal test data and customer cases.<\/em><\/p>","protected":false},"excerpt":{"rendered":"<p>This paper introduces a variety of product air leakage detection methods, including soapy water test, underwater detection method, airtightness meter test and helium detector test.
