Transient cool analyses are used to simulate the change in mold temperature with time. Transient within cycle cool analyses simulate mold temperature deviations from the cycle average.
When an injection molding machine has been working continuously for a period of time, the mold temperatures eventually settle down to a consistent, cycle-averaged temperature. The In-cycle transient cool analysis can simulate the cyclical nature of the mold temperature, and enable you to see the deviations from the average temperature.
