HOW DO EXTRUDER SCREW AND BARREL WORK?

Extruder screw and barrel work together. The extruder barrel contains the screw, the screw rotates in the barrel. When the screw rotates and pushes the plastic material to move forward in the barrel. The heaters are outside the barrel, the heat is transferred to the plastic inside the barrel. When screw thread volume gradually reduces, the plastic in the threaded groove is evenly mixed and plasticized. The action of various forces such as extruders. The screw thread is turning and shearing, and gradually melts into a viscous flow state. At last, it moves to the front of the barrel. Then, completing the plasticization of the plastic. The extruder screw and barrel work together normally to ensure the extruder continuously extrudes raw materials for molding.
