Conical twin screw featurs:

1:Compressing rate of screw can be designed according to different raw materials and products       

2:Twin screw and barrel made: CINCINNATI, BATTENFELD, KRUSSMAFFEI, BAUSANO and AMUT model spares.

Application:      

1)PVC sheet extrusion line,From film to plate, from the wafer to the thick slices, calcium powder content more than 5% ;

2)PVC/PPR pipe extrusion line,the calcium powder *0%***0%,**0%***0%,**0%***0%;       

3)PVC profile extrusion line; PVC/PE wood plastic extrusion line.       

4)PVC palletizing extrusion line,Transparent granulation(create particle good diaphaneity, not yellowing - no exhaust machine barrel),grey granulation (particle good color and luster, full - machine barrel with exhaust)      

5)PVC foam production line,PVC free foaming, crust foaming,half crust foaming;
