Twin-screw extruder for homogeneous mixing and production of foam PE PP

Production process

The extrusion lines produce polyethylene (PE) and polypropylene (PP) expanded foamed by iso-butane and or normal butane gas, 100% recyclable at the  lowest density that can be used in all production fields where it is necessary to insulate, package, protect (for example in building, electronic, mechanical, automotive, food industries).  


extrusion process with direct gas injection

Extruder’s body


Extruders are fully automatic and divided in more zones to control temperatures and pressures levels, equipped with dosing units that ensure a supply of the raw materials with high precision. 
Accurate studies and researches on construction and implementation of the electrical equipment has led to a remarkable power saving method and thus to lower production costs.


The extrusion lines are designed to work 24h a day and therefore built with high quality materials which are treated for long-life use reducing at minimum the maintenance. The process of extrusion by Direct Gas Injection (iso-butane / butane standard) transforms plastic granules (PE-PP) in foam of different thicknesses and densities.


The large range of extruders constructed by Fap allows to satisfy all market production needs:
EXT 314 – 452 – 565 – 753 – 942 – 1256


automatic winders for expanded materials and bubble films

Automatic winders for expanded materials

The twin-screw technology and the special shape of screws allows to obtain the homogeneous mixing of the melt and the better control during the mixing process.
The product comes out from the extruder as a tubular film, consequently to be cut longitudinally for its expansion and cooling on the supporting system and than be winded in reels. FAP has studied a specific winding system that allows obtaining a controlled and constant tension between the spirals of the roll maintaining enough spaces to stabilize the material during post-expansion.
