HFFR & XL-LS0H energy saving extrusion for CPR cables and special applications

Small extruder to produce more than one or two sizes biggest machine

As is well known, flame-retardant materials (HFFR, LS0H and XL-LS0H) are sensitive to heat by their nature and specific composition, so during the extrusion process, large extruders are normally used for medium to small production runs to avoid degradation of the material inside the barrel. This approach drastically increases energy consumption and space requirements, as well as making all activities related to cleaning and maintenance of the cylinder/screw assembly difficult and costly.
At KOMAX we have been developing for more than ten years a family of machines called HELICAL, characterised by a special groove inside the cylinder. This is a groove that follows a helicoidal shape starting from the feed zone of the cylinder itself, reaching various lengths depending on the machine model and relative polymer to be processed.
The benefit offered by this family of machines is to improve polymer plasticisation by reducing initial working pressures and making the extrusion process very smooth and stable.
Thanks to these specifications, a customer using HELICAL can save more than 25% energy compared to consumption with traditional machines.
These performances can also be seen with flame retardant materials such as HFFR, LS0H and XL-LS0H, offering the possibility of using one or two smaller extruder sizes, with all the consequent benefits in terms of footprint and production efficiency.
We remain at our customers' disposal to discuss this topic in more detail and offer a production estimate with HELICAL extruders.
