Composite Manufacturing – Detect Vacuum Leaks

Speeding up leak detection in vacuum bags with ultrasound imaging

Composite manufacturing requires a perfect vacuum integrity before products can be cured. Any leak in a bag can compromise the final product quality and will require additional time for repair.

The methods available to check for leaks are tedious, time-consuming and heavily user-dependent.

Ultrasound imaging is a novel technology that provides a real-time visualization of leaks from a distance. With an ultrasound camera, anyone can pinpoint vacuum leaks 10x faster than before, which improves the process efficiency.

Vacuum Leak detection by ultrasound imaging

How ultrasound imaging works on vacuum leaks

Vacuum leaks create turbulences in their vicinity, on both sides of the enveloppe. These turbulences in turn create sounds and ultrasounds, which propagate to the sensor. The 124 ultrasound transducers of Ultra Pro capture the ultrasounds waves at different times (differing of less than a millisecond). These little time differences are processed by the device in real-time to display the location of the sound source, thus the leak.

Distran ultrasound camera pinpoints leaks instantly. Inspection results are immediate and easy to understand. Anyone can conduct comprehensive, reliable, actionable leak inspections.

Restore sealing integrity on vacuum bags

An essential step to ensure the quality of composite products

After locating a leak, sealing integrity can be immediately restored.
Ultra Pro will confirm if tightness has been reinstated.

Vacuum leaks visualization

Key advantages of ultrasonic imaging for leak detection on vacuum bags

10x FASTER

Ultra Pro speeds up vacuum leak inspections by 10x, especially when compared to traditional single microphone detectors.

REPEATABLE

Ultra Pro is easy-to-use so anyone can find leaks reliably. Pictures from the camera are self-explanatory.

EFFICIENT

Ultra Pro detects leaks from a few meters. No area gets overlooked.

ROBUST

Ultra Pro actively filters background noises and detects leaks even in noisy areas such as production halls.
