Cincinnati Milacron in Batavia, Ohio, and B&P Process Equipment in Saginaw, Mich., have combined B&P’s corotating twin-screw compounding extruder with Milacron’s patented direct extrusion technology for wood-filled profiles into a new line of machines for direct extrusion of wood composite decking. The TimberEx line will be marketed by Milacron. It’s the first corotating twin-screw for Milacron. B&P is building the first model now, a TE125-33 with 125-mm diam. and 32.5:1 L/D. It is capable of outputs up to 4000 lb/hr of decking. Two other models are planned: TE100-33 with 100-mm diam. and output up to 2000 lb/hr and TE 160-33 with 160-mm diam. and output up to 8000 lb/hr. All three have segmented screws and barrels and are available with optional 37.5:1 L/D. The three models have 200, 400, and 800 hp motors. Two vacuum vents with twin-screw vent stuffers prevent clogging.
