Special considerations for leak testing die cast parts

Die casting is a common process in which molten metal is forced under high pressure into a mould cavity that’s created with two dies of hardened steel. In this post, we explore the specific physical characteristics of die cast parts and how these impact leak test. Read More

Factors affecting leak flow rate and how to manage them

We often emphasize that everything leaks. No matter how exact the specifications are, every part will have an allowable air loss measurement compared to a material that shouldn’t leak. Read More

Five common mistakes to avoid with any leak test

That first fact about leak testing is that everything leaks—even if it’s to a very small degree. Read More

Pressure Decay Test Method Guide

There are many different types of leak testing, so when you must test for leaks in the factory or the field, it pays to know which leak test is best for the task. Pressure decay testing is one of the most popular forms of leak testing because it is accurate and relatively easy. Read More

Overview of Mass Flow Testing

When testing parts, if your part-to-part volume differs by more than 5-10% or if you are testing a device that needs to accommodate fluid or air passing through it, chances are you need mass flow testing. Mass flow testing defines the rate of flow through a part or device and is typically conducted ... Read More

Convert Dunk Testing from Bubbles to Measurable Leak Testing

The simplest and least expensive type of leak rate test is dunk testing for bubbles. Even if you know nothing about leak testing, you have probably used a bucket of water to find a leak in an inner tube by looking for bubbles. The principle is always the same—immerse the part and look for bubbles ... Read More

7 Factors Affecting Your Leak Test

If you know anything about leak testing, then you understand that everything leaks. The question is: How much leakage is considered acceptable? For accurate leak testing—and more importantly, accurate leak measurement—you need a repeatable test that gives you an accurate baseline. Read More

5 simple ways to improve your leak test

Leak testing is a common requirement on the production line. It is an important test that ensures the proper functioning of a part or assembly in the field. Due to the importance of this test, it is essential to make sure your test system is always functioning and performing at its best. There is ... Read More

Optical device leak testing: Ensuring military-grade devices stand up to harsh environmental conditions

Military-grade optical sighting devices are an excellent example of how determining the right leak test for the job isn’t just a matter of desired test cycle time and target leak rate. We must always consider the application for the device and the environmental extremes in which it will be used. ... Read More
