NFM: Reliable Counter-Rotating Non-Intermeshing Twin Screw Extruders

When it comes to counter-rotating non-intermeshing (CRNI) twin-screw extruders, NFM understands the importance of reliability in both design and performance. Everything we do centers around the philosophy that you should be able to depend on your polymer processing equipment day-in and day-out.

Originally designed by Welding Engineers Inc., NFM’s experts have mastered the science behind the manufacture of counter-rotating non-intermeshing twin-screw extruders. Our counter-rotating non-intermeshing twin-screw extruder systems have been in service for over 60 years processing virtually every plastic in the world.

The unique features of the non-intermeshing design create the highest free volume and the lowest shear of any twin-screw extrusion process. WE Series extruders enhance feed acceptance, provide superior distributive mixing, enable multistage feeding, and produce optimum venting to accommodate a wide variety of applications over a broad base of polymers. Our screw diameters range from 0.80in (20mm) to 10.00in (250mm).
