AIR LEAK TESTING TECHNOLOGIES
At LeakMaster, air leak testing is our forte. We pride ourselves on having a diverse lineup of leak test instruments providing options for pressure, vacuum and flow, to burst and ramp testing. We back our products with expert service and support you can only find at LeakMaster.
Air leak testing is used to evaluate components, subassemblies, or process systems without damaging or altering the tested product. Air leak testing is performed in a wide range of industries, including medical device, automotive, heavy equipment, aerospace, pharmaceutical and food and beverage manufacturing to ensure product integrity and safety. Air leak testing is a method valued for its efficiency, cost-effectiveness, and ability to be automated for high-throughput production environments.
LeakMaster Air Leak Testing Methods
Pressure Decay Leak Testing
Pressure Decay Leak Testing is a method used to detect leaks in a wide range of products and pressure ranges. Pressure decay is the most widely used method in leak testing. This technology involves pressurizing a sealed part or system and then monitoring the change in pressure over time with a precision pressure transducer. If the pressure drops (decays) it indicates the presence of a leak.
Vacuum Decay Leak Testing
Vacuum Decay Leak Testing is a method used to detect leaks in a wide range of products by drawing a vacuum on the test piece, then monitoring the change in vacuum level over time. If the vacuum level changes within the specified time, it indicates the presence of a leak.
Mass Flow Leak Testing
Mass Flow Leak Testing: Mass Flow leak testing is a non-destructive testing leak method used in a wide range of industries, from automotive parts, medical devices, to industrial components. This technology involves pressurizing a sealed part or system and then measuring the air flow required to maintain the setpoint or target pressure. Flow is deemed to be leakage. If the mass flow sensor detects flow after the part is sufficiently pressurized, it indicates the presence of a leak.
Differential Pressure Decay Leak Testing
Differential Pressure Decay Leak Testing: Differential pressure (DP) decay leak testing is a leak testing method used to detect smaller leaks than pressure decay can effectively measure. This non-destructive technology involves pressurizing a sealed part and a reference volume (dead volume) and then monitoring the difference in pressure between the device under test and the master volume over time. If the pressure difference between the two volumes changes too much, it indicates the presence of a leak (as the master volume should never leak).
Occlusion Testing
Occlusion Testing is a nondestructive technique designed to detect blockages or obstructions that could impede the proper functioning of devices such as catheters, IV sets, tubing sets, or injection molded components. Occlusion setup is relatively simple and can effectively flag a partially occluded part and excessive blockages with ease. Typically, there is no cycle time penalty to a normal test sequence, as the occlusion test is performed in conjunction with the fill step.
Effective air leak testing not only safeguards product performance and safety but also contributes to significant time quality, and cost advantages in manufacturing operations.
