Abstract: A device and process for quickly and reliably determining and recording the configuration of multiple spray nozzles on a spray head assembly used for lubricating a die cast mold reduces trial and error associated with maintenance and repair of the spray head assembly. The device includes an adaptor configured to attach to a spray nozzle and an inertial measurement unit fixed to the adaptor to determine the orientation of the spray nozzle relative to a reference. The method involves using the device to determine the orientation of each of a plurality of spray nozzles on a spray head assembly relative to the reference and recording the relative orientation of each nozzle.
