KUHNE EXTRUSION LINE No-02

EXTRUSION LINE No-02
With an additional extruder from SML

Designed for COEX- castfoil production with additional coating unit.
The extrusion part of the line has 2 extruders; the coating unit has 1 extruder. Processing of thermo plastics in a temperature range of 90-300°C.

Different combinations of production are possible:
-  main unit (CoEx) with coating 

-  main extruder (CoEx) without coating 

-  coating processing over winding unit on an existing base film 


For production in the different described combinations you can lock the not necessary equipment parts.
