Grooved feed barrel

The grooved feed barrel is used for achieving high shear and better transportation of material. As Co-efficient of friction between granules and screw and barrel should be higher to get proper melting of the material, It’s imperative to have grooved feed in the barrel for processing of polymers of Olefin group.
Application:
LDPE/HDPE/PP Film
Raffia/ Mono Filament Application
Barrier Screw

The barrier screw design separates melted material from unmelted solid material into separate channels. This unique mixing feature thoroughly homogenizes the melt with little or no increase in its average temperature. Mixing is achieved with an undulating root profile in the metering zone of the screw.

Application:

  • LDPE/HDPE/PP Film
  • PVC cable
  • ABS
  • PVC Pipe/PVC profile
