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.
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.
