Best answer
The correct choice is (a) True

To explain: In the extrusion process, the extruder includes a water cooling system that circulates around the barrel mechanism. The water cooling system is generally controlled by a sensor that automatically controls the system. The sensor also selects the temperature at a predefined point in the processing section of polymer materials.
