It is recommended to set the value for Maximum Injection Pressure and Maximum Packing Pressure much
higher than the expected pressure to fill the part. If an expectation cannot be derived, 250MPa is a high
enough ceiling to ensure pressure limitation does not occur.
2.4.4.2.2 Filling time
The “Filling Time” in CAE Mode is used to calculate the initial flow rate in simulation. The total injection
volume divided by this time setting gives the initial flow rate for the material through the Melt Entrance.
The “Filling Time” set here is NOT constrained to the input value because complex flow patterns (i.e. shear
heating, hesitation, and leading) may dictate the fill to be longer or shorter than the input value.
The input for “Filling Time” can be defined by a generic processing sheet used for a real part, or by the
equation mentioned in Section 2.5.2. The given default is based on the input mesh geometry and can be
trusted if only looking at filling progression.
