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.
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.
