Pack/Holding Control Profile Settings dialog

This dialog is used to enter a packing profile to describe the pressure applied to the cavity during the packing phase of the injection molding process.

To access this dialog, ensure that you have selected an analysis sequence that includes Fill or Fill+Pack. Click (Home tab > Molding Process Setup panel > Process Settings). If necessary click Next one or more times to navigate to the Fill Settings or Fill+Pack Settings page of the Wizard, then click Edit profile next to the Pack/holding control option.

The parameters used to define a packing profile differ between different models and makes of injection molding machines. Therefore, a varied selection of input methods are available.

You can use shortcuts to edit the input data.

Note: For Injection-compression analysis, the settings below control the injection unit, not the compression unit.

Dialog element	Explanation
Automatic	The solver determines the duration and the magnitude of the packing pressure automatically. The packing pressure remains constant during the packing stage. No entry of the packing pressure profile is needed. This option is available for thermoplastics molding processes in mid-plane, dual-domain and 3d meshes. The packing % value shown on the log file before the end of packing is an estimate, and can change abruptly at the end of packing time.
%Filling pressure vs time	Controls the packing phase of the molding cycle as a function of percentage filling pressure versus time. Click on each box in turn to enter the time (duration) and percentage filling pressure values.
Packing pressure vs time	Controls the packing phase of the molding cycle as a function of injection pressure versus time. Click on each box in turn to enter the injection pressure and time values.
Hydraulic pressure vs time	Controls the packing phase of the molding cycle as a function of hydraulic pressure versus time. Click on each box in turn to enter the hydraulic pressure and time values.
%Maximum machine pressure vs time	Controls the packing phase of the molding cycle as a function of percentage maximum pressure versus time. Click on each box in turn to enter the time (duration) and percentage maximum pressure values.
