According different material and different plastic product to choice different compress rate and L/D    Twin screw and barrel made: CINCINNATI, BATTENFELD, KRUSSMAFFEI, BAUSANO and AMUT model spares  
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.
Application:
PVC Pipe,PVC sheet,PVC profile,PVC pelletizing,PVC foaming,WPC+PVC,WPC+PE and etc.
