Using heating elements to heat the hot runner

Heater elements can be modeled and used to heat the hot runners. The Cool (FEM) analysis sequence must be set in order to take advantage of this feature.

Select the Dual Domain Cool (FEM), or 3D Cool (FEM) analysis sequence.

1. Import the model, and mesh each component separately.
2. Assign relevant element properties, such as part, mold, cooling channel, etc. to all components.
3. Select all components of the hot runner channel in which molten plastic flows, and assign to them the property 'Hot runner (3D)'.
4. Select the all components of the heater element and assign to them the property 'Heater element (3D)'.
5. Select all other modeled hot runner components and assign to them the property 'Mold insert'.
6. Select the heater element (3D) components, that is the hot runner components in which the molten plastic flows, right click and select Properties from the drop-down menu.
7. In the Hot runner (3D) dialog box, select Use heater element from the Heat loss into mold option drop-down box. This will allow the plastic inside the runner to assume the temperature of the heater element.
8. Set all the process settings and launch the analysis.
