Temperature, mold-circuit interface (transient from start-up) result

The Temperature, mold-circuit interface (transient from start-up) result shows how the temperature at the interface between the mold and the cooling channels changes during the start-up cycles, until the mold temperature stabilizes.

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 from start-up) result will typically be between 10ºC and 30ºC below the mold-cavity interface (transient from start-up) 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 from start-up) result, watch for the following.

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