Determination of processing data: Metering performance

If the screw shape is fixed, the metering performance (plasticising capacity) of a material can be one of the parameters that determine the cycle time in the injection molding process. It describes the volume flow rate from the hopper to the space in front of the screw in the plasticising unit and is given in cm³/min.
