Special screw for PP containing long glass fiber

Long glass fiber Open fiber Chip Low shear Metal substitution Module Exchange path check ring Low shear screw design Air shot

Introduction to Technology
Special screw for PP containing long glass fiber
Special screw for PP containing long glass fiber
Plasticization technology for modules of large-scale molded parts (automobile parts)
High strength, high heat resistance, and lighter weight (substitution of metal material)

Its super slow compression and large lead flight form effectively inhibit breaking of long glass fibers (GF) and long carbon fibers (CF) while fibers are untangled and dispersed homogeneously with the very minimum mixing

Screw design
  • Achieves customer's plasticization requested quality through the use of an optimum design that controls shear during melting.
Wide flow path check ring Low shear screw design
