Incotech manufacture bespoke leak testing machines and fixtures. These generally utilize the pressure decay method of testing, which works by pressurising the component with low pressure compressed air, sealing off the component and then monitoring any drop in pressure. Comparing the results with established criteria will determine if the test is a pass or fail.
Automated leak test machines can incorporate fixtures to hold and clamp the component, actuated sealing devices to close off any fixed openings in the component, safety enclosure and test pass/fail indication or part marking.
Alternative leak testing media are available depending on the test requirements e.g. water, oil, nitrogen, helium.
Incotech also manufacture our own basic leak testing instrument, which is generally used for manual offline testing of standalone components.
