Parallel twin screw and barrel
Specification:
(Co-rotating and Counter-rotating)Parallel twin screw and barrel:
35/2,45/2,50/2,65/2,80/2,90/2,105/2,125/2,130/2,150/2,180/2,200/2 etc.
We also can make screw and barrel for CINCINNATI, BATTENFELD, KRUSSMAFFEI, BAUSANO and AMUT model spares!All according to different material and plastic product to choose different compress rate and L/D!
The advantages:
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.
