  • Check machine conditions:

  • 1. Ensure that heats are at set points and have stabilized for at least 15 minutes

  • 2. Check shot size to ensure that it is not set extremely high or low.

  • Check the switchover position to ensure that it is set at a position well away from forward, approximately at 1 to 1.5 inches, depending on shot size.

  • Check to ensure that hold pressure and time are either turned off or at low settings.

  • These things are done to prevent flashing or over filling of the mold. This is when damage is likely to occur if too much material is injected into the mold too fast or with excessive pressure.
