Extruder heat balance calculations evaluate the energy distribution within the metering section of a polymer screw extruder. Mechanical power from the screw rotation generates thermal energy via viscous dissipation, which must be balanced by sensible heat gain in the melt and barrel cooling duty. Determining the required cooling duty ensures accurate temperature control and prevents polymer thermal degradation during processing.
