For an industry that produces sealed products, leak testing is a very important aspect of device quality control. This is so because any crack could result in the impregnation of moisture or any other trace gas inside. This could lead to corrosion, fogging, and ultimately reduce the life of the device or the product as a whole. If you are a manufacturer of quality products then it is a cause for concern as it could affect your brand reputation.
So you can see that leak testing is quite essential and needs to be done on airtight devices before they are released on the market. For these types of tests, there are many techniques available today. Let's analyze some of the most popular among them. If you are looking for Package leak detection, then you can browse the web.
• Dye Impregnation – A fluorescent dye is used here to check for defects. Here, said dyes are impregnated on the hermetically sealed device and then it is checked if there is any problem in the packed seal. The advantage of this method is that it eliminates the problem of misinterpretation that often occurs when sectioning brittle materials.
• Krypton 85 test – This type of testing technique is used to check for fine and large leaks in sensitive sealed devices. Here, the radioactive element Kr-85 is used as a tracer gas and mixed with air. This composition is made to pressurize the glass cubicle in which the device is kept. If there are cracks, this gas would enter that space. The presence of Krypton can be easily verified by using X-ray crystals.
• Helium Test: This test method is quite similar to the Krypton-85 method. The difference lies in the tracer gas used since it uses helium here. It can be done to analyze both fine and large leaks.
These test methodologies provide the desired results, but which method is best for you will depend on the product you manufacture. If you are dealing with similar items and you need such testing services, you can consult with the supplier about which technique will suit you.
