NFM/Welding Engineers highlighted new developments in wood/plastic composites extrusion at NPE.
The TEM series of co-rotating, intermeshing compounding machines offer high torque per free volume and high screw speed. The Massillon, Ohio, company claims the TEM allows no drying or pre-mixing to cut costs and space. NFM said the TEM series is available in barrel diameters of 26-240 millimeters.
NFM also showed its SPX series of single-screw extruders that can compound wood/plastic composites. The series is available with barrel diameters of 11/2-8 inches.
The WE series of extruders is geared to applications such as devolatilization, reactive extrusion and recycling. The counter-rotating, nonintermeshing machines can compound long-fiber-reinforced products with low shear.
NFM also displayed its new Aries process control system, object-oriented system designed to use visibility, animation and touch to perform a variety of tasks cost effectively.
