In order to determine the temperature on the wall of an injection mould, cavity temperature sensors specially designed for this application are used.
The reaction time of the sensors plays a major role here.
The aim is to be able to detect the position of the melt front in real time. The temperature sensors thus functions as a kind of light barrier in the mold.

They can also be used to analyze the temperature profiles in the cavity.
With this, the sensors are used for monitoring, switching and closed loop controls within the injection molding process.
