Rapid Leak Inspection Technologies

Request Number N778842
Need details

Automobiles are exposed a variety of different weather conditions and, as such, are expected to resist intrusion by outside water. To ensure that a seal is water-tight, the module undergoes a leak test, which can be costly and time consuming. IncWell's partner seeks innovative leak testing methods that can increase processing speed by reducing test cycle time.



Automotive manufacturers need to provide water-tight seals in a variety of locations on the car body: around doors, around windows, anyplace where the potential for water intrusion exists.The current method for evaluating a module for leaks Pressure Decay / Mass Flow. This technique is effective but can be slow, ranging from a minimum of 160 second to more than 360 seconds. Large leaks, those 1.0mm and larger, can generally be found relatively quickly. Smaller leaks take longer and increase cycle time.


Additionally, some leak testing procedures involve water, which can also increase cycle time due to the need to clean up after the testing in complete.

Key Success Criteria

The successful technology:

  • Cycle time of 45s or less
  • Ability to detect very small leaks greater than or equal to 0.3mm in diameter
  • Process that does not create additional steps, such as post cleaning of tested components / modules
  • Ability to test large parts (up to 1.5m x 1.5m)
  • Occupy a relatively small footprint


Possible Approaches

IncWell's partner is interested in any technology capable of achieving the performance stated above.


Approaches not of interest
  • Water Leak Process (time consuming to clean up the water)
  • Vacuum Decay (cycle time too long)
  • Ultrasonic Flow (unacceptable performance)
  • Thermal Escape (unacceptable performance)
  • Thermal Paper (unacceptable performance)


Preferred Collaboration types
  • To Be Negotiated
Items to be submitted
