Temperature, mold-circuit interface (transient) result

The Temperature, mold-circuit interface (transient) result shows how the temperature at the interface between the mold and the cooling channels changes over the duration of the cycle.

Using this result

Use this result to determine whether the cooling channels are cooling effectively, or whether their placement will affect cycle time and part warpage. If there are hot or cool spots, you may need to adjust the cooling channels, or coolant temperature. Cooling channel placement and the thermal conductivity of the mold will affect the temperature variations.

The Temperature, mold-circuit interface (transient) result will typically be between 10ºC and 30ºC below the mold-cavity interface (transient) temperature. If an automatic Injection + Packing + Cooling time is used, a coolant temperature too close to the target temperature will significantly extend the predicted cycle time.

Tip: You can create an XY plot of the transient mold-circuit interface temperature, on any given node, to see how the temperature at that node varies with time. Click on Results in the Results pane of the Home tab, then click (New Plot > Plot) and scroll down to the result. Remember to change the Plot type to XY plot.

Things to look for

When viewing the Temperature, mold-circuit interface (transient) result, watch for the following.

• Localized hot or cold spots.
• The cooling pattern. Is it evenly distributed?
