Q&A: Which products need airtightness testing equipment? Comprehensive analysis of industry applications

In the manufacturing quality inspection segment, theAir tightness testing equipmentIt has become an essential tool. It can quickly determine whether the product is leaking air, liquid, water and other problems, and help companies to control the sealing and waterproof performance.

So.Exactly which products need to do airtightness testing? If you are a purchaser or engineer working in manufacturing, this article will give you a clear guide to getting started.

I. Consumer electronics

As electronic devices tend to become thinner, lighter and more waterproof, theAir tightness testingIt has almost become a mandatory test before leaving the factory.

• Typical Products: Smartphones, smartwatches, Bluetooth headsets, tablets, camera modules.
• test purpose: Waterproof, sweatproof and dustproof to enhance the user experience.
• Detection Methods: Positive pressure, negative pressure or volumetric quantification methods are mostly used, which are fast and efficient.

In these scenarios, thePrecision EngineeringAirtightness TesterIt has been widely used in a number of leading domestic consumer electronics companies to help them realize batch fast testing.

VIII. Frequently Asked Questions (FAQ)

Q1: Do all products have to be tested for air tightness?
A: Not necessarily.It is only necessary for those products that require high levels of waterproofing, dustproofing or safety.

Q2: What is the difference between airtightness testing and IP waterproofing testing?
A: IP Testing(also known as the real water test)It is the overall protection level verification, while the airtightness test is more suitable for quick determination in the production process. The two are often used in combination.

Q3: DomesticAirtightness TesterCan it replace imports?
A: Totally.Jingcheng Industrial Technology as the representative of domestic manufacturers, in the life of home appliances, consumer electronics and medical equipment testing has been the same as the international brands, by virtue of the new energy and automotive parts industry for many years of deep cultivation, more than the international brands, to become the first echelon, and have the advantage of localized services.

Q4：Can Precision Engineering provide airtightness meters for different methods?
A: Yes.Precision Engineering provides positive pressure method and negative pressure method.(vacuum method)Differential pressure method, flow method, volumetric quantification methodAir tightness testerand helium detection and other equipment, can cover the whole scene from consumer electronics to power battery, support non-standard customization.
