Specifying a packing profile

A packing profile is used to control the packing phases of the molding cycle.

It is used after the velocity/pressure switchover point has been reached at the end of filling. Packing profiles are used to control the volumetric shrinkage distribution, and to avoid overpacking and related problems. The profile only needs to describe the time when a packing pressure is applied.

Note: You do not need to enter the cooling time in a packing profile.

1. Ensure that you have selected an analysis sequence that includes Fill + Pack.
2. Click (Home tab > Molding Process Setup panel > Process Settings Wizard).
3. Select the Advanced tab, and then select the required option from the Time vs. drop-down list.
4. Enter the packing profile data into the table provided. The left-hand column represents the time in seconds, and the right-hand column pressure values. You can use the table by clicking on each box and entering the profile data.
5. Click Plot to preview the profile you have entered.
6. Click OK to close the plot profile.
7. Select the Automatic cooling time option to have the cooling time calculated during the Fill+Pack analysis, or deselect it to specify the cooling time manually.
   Note: The cooling time is the additional time after the end of the packing phase. This time allows the part to freeze at at least 80% through the thickness and become solid enough to be ejected.
8. Click Finish to close the dialog, or Analyze to launch the analysis.
