Nine-Zone Extruder Temperature Control System with ±1°C Accuracy and Cast Aluminum Heaters

Precise temperature control is fundamental to ensuring uniform plasticization and stable extrusion of PP material. This extruder features 9 independent cast aluminum heaters (6 zones on the barrel, 3 zones on the die head) and 6 centrifugal cooling fans, forming a fully automatic closed-loop PID temperature control system. The system monitors each zone in real-time, automatically adjusting heating or cooling to keep deviations within ±1°C, ensuring uniform melt temperature. This fine temperature control capability effectively avoids quality issues such as poor plasticization, gels, and uneven thickness caused by temperature fluctuations, laying the foundation for high-precision, high-stability extrusion production.
