Introduction to Technology
F screw for high viscosity resin
Gradual compression mold F screw
Features
  • Moderate resin compression and small heat generation
  • Low resin temperature
Effect
  • Decrease of haze and yellowing
Stop time and plasticizing capacity of resin (test cycle [test conditions: plasticization 25 seconds, screw stop time: n seconds]) graph
Step land flight
Screw / barrel cross section Normal flight shape and step land flight shape Step land effect (reduction in local heat generation due to pressure pressing flight back from barrel)
