The Part Surface Properties tab of the Cold runner (3D) dialog is used to specify the geometrical properties of the cold runner.
The collection of property values defined on the dialog are saved to a property set with the description shown in the Name box. In addition, you may be given the option to also apply the property values to related entities in the model.
Dialog elements
- Local heat transfer coefficients
- Specify the heat transfer effectiveness (HTE) criteria to be applied to the selected tetrahedral elements.
- Use global setting in advanced options
- Use this option if you want to use the thermal properties specified in the Advanced options of the Process Setting Wizard.
- To view the global settings,
- Click
.
- Click Advanced options.
- In the Solver parameters group, click Edit.
- Select the Mesh tab.
- Click
- Perfect contact
- When selected there is no heat resistance between the part and the mold surface. When this option is selected the wall nodes are a fixed thermal boundary for analysis purposes.
- Local heat transfer coefficients
- Allows you to specify the heat transfer coefficients for the selected tetrahedral elements. Click Set to adjust or view the Heat Transfer Coefficients for the selected tetrahedra.
Note: When assigning the heat transfer coefficient to an in-mold label, it is the ratio of thermal conductivity of label to the thickness of the label. - Mold surface temperature
- Specify how the mold surface temperature of a selected area on the surface of the model is defined.
Use mold surface temperature in process settings- the value is obtained from the
Process Settings Wizard, and used throughout the molding cycle. This option is selected by default.
Constant - this option allows you to specify a constant temperature for the selected area, which is different from the temperature value that is assigned in the Process Settings Wizard.
Profile - this option allows you to define a varying mold surface temperature for the selected area throughout the molding cycle.
