Engineers at PNR Italy have developed QA testing robots that can check the quality and operational accuracy of every nozzle the company produces. PNR’s Australian distributor Tecpro Australia director Patrick Cooper said the robotic testing in action is fascinating.

For diameter testing, a robot picks up each nozzle on the conveyor belt, then orientates it so a video camera can check it. Using this robot, PNR Italy can check 720 nozzles per hour, or around 11,500 nozzles a day.

This process is used for both their regular nozzle production line as well as their custom designed nozzles, Cooper said.

The PNR production plant also offers specialised robotic testing for nozzle performance. These water tests can check droplet size, flow rates, spray angle and other important quality assurance attributes at speeds of up to 3000 nozzles per day.

The PNR robot can also conduct air testing and check component labelling compliance.

All tests conducted by PNR include detailed reports, which provide a range of statistics such as upper and lower pressure tolerances and flow rates.
