Temperature, part (transient, profile) result

The Temperature, part (transient, profile) result is a Dual Domain result that shows the temperature of the part, calculated for each time step of the cycle and plotted at the point where the normalized thickness = 1.000.

This profile is based on the transient mold surface temperature at each time step. The temperature laminate results are calculated using a finite difference method through the thickness of the part.

This calculation takes into account the Mold-melt Heat Transfer Coefficients (HTC) values, which you can set on the Mesh tab of the Solver parameters dialog, in the Advanced options of the Process Settings.

Tip: The lower the HTC value, the greater the resistance to heat transfer between the polymer and the mold.

Using this result

To see how the temperature varies through the thickness of the part, you can create an XY plot of the result at different points. To do this, click (Home tab > Results panel > Results), then click (New Plot > Plot) and scroll down to the Temperature, part (transient, profile) result. Remember to change the Plot type to XY plot, and on the Plot Properties tab, change the Independent variable from Time to Normalized thickness.

Use this result to find localized hot or cold spots, and determine whether they will affect cycle time and part warpage. If there are hot or cool spots, you may need to adjust the cooling channels.

The difference between the temperature across the top or bottom face of the part and the target mold temperature should not be greater than ±10°C.

The part temperature can be studied more closely by reducing the temperature range. To do this, click on (Home tab > Results panel > Results), selecting (Scaling pane > Set Scale) and decrease the value in the Max box.

Note: If you animate the result, it will show you how the temperature changed over the duration of the analysis inside the solid model.

Things to look for

When viewing the Temperature, part (transient, profile) result, watch for the following.

• Regions that freeze off early. The gate should not freeze before the part.
• Hot and cold regions.
• The cooling pattern. Is it evenly distributed?
