Introduction
This technical note addresses the detection of vacuum leaks in the infusion process used in the construction of composite parts for the aerospace industry, boat hulls, wind turbine blades, and other composite components.

Vacuum Infusion Process
The vacuum infusion method, also known as the SCRIMP method, involves injecting resin into a closed structure composed of an open mold covered with a hermetic cover containing glass fiber. This setup is connected to a vacuum installation. Ensuring the system is leak-tight under vacuum pressure (between -0.5 and -0.9 Bar) is crucial before infusing the fiber with resin.

Problems with Vacuum Infusion
Leaks in the plastic cover can lead to non-uniform resin dispersion, resulting in imperfections in the final product. Leaks around the inlet connector can cause resin loss, reduced efficiency, increased production time, and decreased profitability.

Vacuum Leak Detection Solution
The LEAKSHOOTER LKS1000, equipped with combined vision and ultrasonic detection technology, can detect leaks by scanning the upper zone sheeting, holding seals, and inlet connector from approximately 1 meter away. Once a leak zone is identified, a flexible probe can be used for precise leak checking and necessary repairs. This procedure can be conducted with or without headphones, aided by an automatic and dynamic target on the screen during leak detection.
