Safety component such as airbags are inflated by gas produced during the combustion of pyrotechnic material or release of stored gas. A leak present in an airbag inflator will deteriorate its performance either by ingression of moisture or loss of pressure. Leaks this small can only be detected with a helium leak detector. Select a category below for applicable leak testing equipment and to see examples of LACO's projects.
Helium Vacuum (HV): An automated method where the test part or test fixture is evacuated to full vacuum while helium is introduced to the opposite barrier of the part.
Air Testing (AT): A variety of automated test methods using air as the test media for detecting leaks by pressure decay or mass flow.
Helium HATSTM (HH): A patented (U.S. Pat. No. 7,905,132) automated method of capturing and accumulating helium in an enclosure (evacuated to partial vacuum) surrounding a part pressurized with helium.
