Specifying different mold temperatures for cavity/core by surface

In the injection molding process, there are areas of the mold that may have a higher or lower temperatures due to part/mold design. A Cool analysis will predict and take into account such local variations in the temperature of the mold.

If you do not have the Cool module, however, you can manually assign separate cavity-side and core-side mold temperatures to assess the effect these variations.

To set separate cavity-side and core-side mold temperature values for a surface, complete the following steps.

1. Click (Home tab > Molding Process Setup panel > Process Settings).
2. Click Advanced Options..., then click the Edit button next to the Process controller option.
3. Click the Temperature Control tab, select Cavity differs from core in the Mold temperature control drop-down, then click Edit mold temperatures.
4. Enter the required cavity-side and core-side mold temperatures values, then click OK to accept the changes.
5. Click OK twice to return to the Process Settings Wizard, navigate to the final page of the wizard, then click Finish.
6. Click (Mesh tab > Mesh Diagnostics panel > Orientation), then Show to display the orientation of all elements.
7. To check the cavity/core assignment in various areas of the model, select a group of elements in the model pane, right-click and select Properties, select the Mold Properties tab.

Note: For Dual Domain models the cavity/core side assignment must be set to specify which mesh surface is in contact with the cavity side of the mold and which mesh surface is in contact with the core side of the mold. If this is not set, both surfaces will use the cavity temperature setting.
