• Exploring The Structure And Functions of Extruder Screws

  This article explains the structure and function of extruder screws, which are divided into three main zones: the feeding zone, where solid resin is transported and preheated; the compression zone, where the resin melts through external heating and shear heat; and the metering zone, which ensures uniform extrusion. Additionally, the article discusses darmage(a mixing section), screw elements used in twin-screw extruders, the compression ratio affecting resin flow and pressure, and the barrel, which houses the screw and facilitates heat transfer. Proper screw design is essential for optimizing resin plasticization, mixing, and extrusion efficiency.
