- 18. The method as in claim 17 wherein each pressure sensor is attached to its respective opening via an adapter.
- 19. The method as in claim 18 wherein the adapter is operable between an open position wherein fluid flow communication between the pressure sensor and its respective opening is present and a closed position wherein fluid flow communication between the pressure sensor and its respective opening is absent.
- 20. The method as in claim 17 wherein each pressure sensor is a MEMS pressure sensor.
- 21. The method as in claim 17 wherein the readings of the plurality of the pressure sensors are taken by a data acquisition and processing device.
- 22. The method as in claim 21 wherein the data acquisition and processing device is a computer.
- 23. The method as in claim 17 further comprising the step of providing a reject hole located within the mold.
- 24. The method as in claim 17 further comprising the step of providing a PIN hole located within the mold.
- 25. The method as in claim 17 further comprising the steps of:
providing a flow meter fluid flow connected with the inlet port; and taking the readings of the flow meter.
- 26. The method as in claim 25 wherein readings from each of the plurality of pressure sensor and the flow meter are taken by a data acquisition and processing device.
- 27. The method as in claim 26 wherein the data acquisition and processing device is a computer.
- 28. The method as in claim 17 further comprising a resin pump fluid flow connected to the inlet port.
- 29. The method as in claim 28 further comprising the steps of:
deactivating the source of pressurized gas; removing each of the pressure sensors from is respective opening; providing a plurality of plugs each inserted within a respective one of the plurality of openings; and activating the resin pump.
- 30. The method as in claim 29 further comprising the steps of:
providing a flow meter fluid flow connected with the inlet port; and taking the readings of the flow meter.
- 31. The method as in claim 30 wherein readings from each of the plurality of pressure sensor and the flow meter are taken by a data acquisition and processing device.
- 32. The method as in claim 31 wherein the data acquisition and processing device is a computer.
- 33. The method as in claim 17 wherein the pressurized gas is nitrogen.
