Estimating the term…
An injection unit for a molding machine, including a mass cylinder, an injection actuator, which injection actuator is configured to expel a plasticized molding compound from the mass cylinder via an injection nozzle, at least one sensor which is configured to detect a time-resolved, characteristic signal for the driving force of the injection actuator, and an open or closed loop control device for open or closed loop control of the injection actuator, which open or closed loop control device is configured to receive the time-resolved, characteristic signal of the at least one sensor. The open or closed loop control device is configured to carry out the following steps: controlling the injection actuator to perform a movement towards the injection nozzle, recording the time-resolved signal characteristic of the driving force of the injection actuator, determining a substantially constant force level for a period of time, preferably before a significant increase in injection force level follows, and preferably calculating the pressure loss (Δp) based on the first force level.
