A major automotive oil filter manufacturer requested an operator-free testing system that would allow for checking the absence or presence of threads in the tap plate of finished filters entering our equipment from a seaming station.

Our solution included designing & fabricating a continuous motion testing turret system which automatically accepted finished filters straight from a seaming station, positively control, transfer & insert them into our checker which inserts probes into a hole, injects air & based upon the pressure generated, determine whether the part is threaded or not.

Special considerations included:

• Providing a system capable of accepting filters for inspection.
• Accepting the filters automatically without the need for an operator/attendant.
• Rejecting to an isolated area any filters without threads.
• Accomplishing  the testing without damaging any of the surfaces of the filter & without affecting functionality in any way.
