An extrusion line produced by Friul Filiere, based in Buia (Udine, Italy), has made it possible to introduce the world's first decking profile using the FFC (Foam Fibre Composite) ultra-light composite.
To process such a composite, the new Omega S Evolution line has been designed with counter-rotating twin-screw or special single-screw extruders. In the latter case, a degassing system makes the process cheap without altering product quality. Moreover the screw has been redesigned exploiting the energy deriving from shear stress, self-feeding the thermoregulation of the barrel-screw unit. The compression rate now provides an increase in output of 40-50% running at the same screw rpm.
