Farcon’s coextrusion feedblocks mainly differ in coextrusion feedblocks at fixed geometry and coextrusion feedblocks at variable geometry. Here following the overview of different types:
COEXTRUSION FEDBLOCK |
||||||||
|---|---|---|---|---|---|---|---|---|
| FIXED GEOMETRY | VARIABILE GEOMETRY WITH DISTRIBUTION PINS | |||||||
| AT VARIABLE STRUCTURE | AT FIXED STRUCTURE | AT VARIABLE STRUCTURE | ||||||
| WITH LAMELLAR DISTRIBUTOR | SIMPLE | WITH DRAWERS | 2 ways + 1 direct / 2-3 layers | 4 ways + 1 direct / 2-3-5 layers | 6 ways + 1 direct / 2-3-5-7 layers | |||
| simple | with interchangeable out of axis plates | with interchangeable aligned plates with blocking wedge | 2-3 ways / 2-3 layers | 3-4-5 ways / 2-3-5 layers | ||||
Coextrusion feedblocks at fixed geometry
Farcon’s coextrusion feedblocks at fixed geometry can be:
- at variable structure, thanks to a lamellar distributor that splits the structure into small layers.
The stratification may also be obtained by interchangeable distribution plates (out of axis or with blocking wedge) by means of which you get different structures.

Coextrusion feedblocks at variable geometry
Farcon’s coextrusion feedblocks at variable geometry and variable structure are equipped with devices that allow the change of the percentage of coextruded material according to the production needs. With these coextrusion feedblocks, the structure’s changes are extremely rapid thanks to the replacement of the selector plug.
1 to 7 layers 6 distribution pins
1 to 3 layers 2 distribution pins
