Overview
The single-screw extruder is the most versatile and fundamental piece of continuous mixing and shaping equipment in the polymer processing industry. Acting as the "heart" of plastics production, it utilizes a rotating screw inside a heated barrel to perform sequential operations including feeding, compaction, melting, mixing, homogenization, metering, and pumping. The final melt is continuously forced through a shaped die to produce products with constant cross-sections or to feed subsequent processes.
Working Principle (Three-Zone Model)
The core principle relies on drag-induced flow from the rotating screw, combined with friction and external heating from the barrel. The material undergoes three physical transitions:
  • Feed Zone (Solid Conveying): Granular or powdered material enters from the hopper. This zone has the deepest screw channel for solid conveying, where screw rotation pushes material forward while heating and friction begin preheating and compaction.
  • Compression Zone (Melting/Plasticating): The screw channel depth gradually decreases, creating compression. The compacted solid plug undergoes increasing shear and pressure, forming a melt film that is scraped off and collected until material is fully molten.
  • Metering Zone (Melt Pumping): This zone has the shallowest constant channel depth for homogenizing the melt, providing stable conveying, and acting as a precision pump to deliver material to the die at constant pressure, temperature, and flow rate.
