What to Look For in Leak Detection Equipment

One of the greatest concerns of quality control is the sealing integrity of a package. If it is overlooked, there is a likelihood of incurring heavy financial losses as a result of recalling of the products, court fines for harm to persons who’ve used damaged products as well as loss of the company’s good image. In addition, the company may face stern action from regulatory authorities which may all greatly hurt the business. Therefore, investing in high quality leak detection equipment is not only cautious, but also smart.

Possible Leak Causes

Mostly, damages that lead to leaks happen in the packing process. On the other hand, improper packing can be caused by several factors. It may simply be a result of misalignment during the creation of a thermal seal. It may also be caused by the presence of the product’s particles on the sealing material thus preventing proper sealing. Additionally, the heat level, duration, and pressure used during the sealing process may not have been appropriate to the particular packaging process.

Your Leak Detection Equipment should be accurate and quick in picking out any of the many problems associated with wrong package sealing. This way, it will help you avoid serious damage to the brand’s reputation. Keep in mind that it will cost you a lot more to get back consumers’ trust after a packaging failure than it will to obtain the equipment.

Efficiency and Ease of Operation

Needless to say, one of the most important features of any equipment is easy operation. In addition, any equipment meant for detecting leaks should be able to help the user find holes in the smallest possible sizes when checking sealed and non-porous packages. Moreover, it should prove its worth by delivering quick results. Remember, you should not have to put the packages through various leak testing methods including traditional ones such as water bath leak detector after using the detector.

Non-Destructive Leak Testing

In most cases, leakage problems are brought out by defects in the packaging material or process—not the product. While certain products cannot be used once packed, others do not have to be discarded once leakages are discovered. In the latter case, non-destructive leak detection equipment should be put into use. Improperly sealed products can then be returned to the packaging line for a better job thus pushing losses incurred as a result of unnecessary wastages to the minimum.

There are various other factors to look out for in leak detection equipment. They include adaptability to the use of different methods of testing for leaks such as bubble emission and vacuum decay. Moreover, the equipment should support factory automation as well as have the ability to get rid of human error during testing. Lastly, remember that there are online and offline applications for leakage detection as well as process control in QA/QC.

The 4 Kinds Of Leak Detection Testing

Even a tiny flaw in a seal or container can have severe consequences when handling liquid or gas compounds. Leak detection equipment is an essential part of the storage and transportation process, particularly for volatile or toxic substances that could pose an imminent threat to other people. There are several techniques commonly used to identify leaks in packages, so test selection depends on the size and type of the container in question.

Bubble Emission Test

As its name suggests, the bubble emission test requires submersing the container in water to see if it releases visible bubbles. This test requires a vacuum pump, since all the air must be removed from the water chamber after the package is submerged. The package will expand slightly once the air is gone, which forces the air inside the container to come out if it can.

Those conducting the test must be careful about the potential for false positive results, since small air bubbles can get trapped on the outside of the container when it is submerged. This test also takes at least 30 seconds per container, which can be impractically slow depending on the type of product. However, bubble emission is a popular choice because it is relatively cheap and reliable.

Vacuum Package Test

The vacuum package test is a variant of the bubble emission method that is specifically designed for containers that are packed or unpacked with a vacuum. It requires a small attachment that maintains stability and integrity of the container while submerged. With the exception of additional Leak Detection Equipment required to test vacuum packages, the results and reliability of this method are the same as bubble emission.

Dry Chamber Test

The dry chamber method was developed primarily to test smaller packages that contained a liquid compound. Since these packages are designed to conserve space, they generally have little air trapped inside. Instead of submerging them in liquid, this test requires an absorbent material to be wrapped around the container in a vacuum environment. The container passes the dry chamber test if no liquid was forced out of the container by the suction.

Altitude Simulation Test

Air pressure has a profound effect on packages and components that store liquid or gas substances. The altitude simulation test creates an artificial environment that mimics the low pressure situation the container might encounter. It uses a method similar to the dry chamber that subjects the package to a low pressure environment. This change can alter the properties of compounds, causing them to burst through faulty or poorly designed containers.

The Benefits of Advanced Leak Detection Equipment

Leaks are not only messy and potentially dangerous, they can also lead to significant financial loss for companies transporting valuable products or materials. It doesn’t take much to allow gas or liquid to escape, so it’s important to make sure all packages are in perfect condition before putting them to use. Leak detection tests are easy to do, require little investment and produce reliable results.
