Parallel double screw and barrel for Weber DS10.22 pvc extruder

(Co-rotating and Counter-rotating)Parallel twin screw and barrel:













Features:Screw and Cylinder adopt blocking structure, can update and maintain comfortably!

Screw&Cylinder also can be made:


According to different material and plastic product to choose different compress rate and L/D!


1. Parallel twin screw and barrel has the advantage of lower rotation speed, smaller shear   stress between the  small screw

2. Good plasticization, high productivity, small shear force, stable pressure , less wear and tear and low cost.

3. Parallel twin-screw and barrel is widely used in PVC products processing, especially for the production of PVC products with the output over 350Kg / h, because the parallel twin-screw and barrel costs less than conical twin-screw and barrel while it has more mature technology.

4. Parallel twin-screw and barrel is successfully applied in PVC plate, pipe, profile, pellet and mould, at the same time, it solved the technical problem of low foaming, high foaming, high filling, wear and corrosion.
