Because the total part weight changes with time, the %Shot weight result measures the total part weight, as a percentage of the total part weight, at various time-steps during the filling analysis.
The total part weight is determined from the room-temperature density and the total volume defined in the finite-element mesh. From this information, you can decide if removing the holding pressure will influence the shot weight. The percentage runner weight is also displayed with reference to the total part weight. The economics of the runner design can be assessed by considering its percentage weight in the total shot.
