screw barrel for extruder machine processing PE pipe

This set of screw barrel is for PE pipe,the screw size is ø65*2120mm,barrel size is ø 105*2030mm.
Screw treatment: Bimetallic
Barrel treatment:Nitrided


Product Show:

We design two different mixing head on the head of the screw,that will help the plastic material out put equally.
