The current method for leak detect has been tapping on the top of lid and sensing the pressure. This is difficult technique with low accuracy.
solution is to sense the side of bottle by pushing with specific force and determining the movement to determine pressure in bottle. If there is a leak the spring back is greater. The cycle rate is 20 Hz. Since the SMAC actuator can sense the surface, apply programmable force and monitor position of movement it is a game changing solution, much more accurate than vacuum decay / pressure decay leak testing.
This same in-line inspection solution can be used for soft pouch packaging such as contact lenses or coffee "pods."
