By means of the replaceable screw barrel sections, the processing sections is devided into individual zones. The barrels are heated electrically. In addition, the barrels are provided with longitudinal bores for cooling with water. Uniform temperature distribution, namely on the circumference of the eight-shaped barrel bore, is achieved by a reverse force-flow temperature control circuit. Connections of pipes for temperature control are in groove-tongue design to balance alternating thermal stress and avoid leakage.
The screw barrels are made of nitrided steel. In order to increase the service life of the screw barrels, these are provided with wear resistant inserts.
