DIE SET AND METHOD FOR MAKING EXTRUDED SYNTHETIC WOOD USING CELLULOSIC COMPOSITES FORMED USING A DIE WITH A TWO DIMENSIONAL ARRAY OF NON-UNIFORM CHANNELS

摘要

592182 Disclosed is an apparatus for extruding cellulosic plastic composites or synthetic wood. The apparatus comprises a source of extrudate flow; and a stranding die configured to receive extrudate from the source of extrudate flow, for use in an extrusion system configured and dimensioned to adjust flow rate of extrudate therethrough and/or increase consistency or strength of an extruded composite. The system includes a sloping, front perforated surface; a rear perforated surface; and a plurality of non-uniform channels extending from the front perforated surface to the rear perforated surface and forming a two-dimensional array of openings in each of the front perforated surface and the rear perforated surface. The source of extrudate flow is configured with respect to the stranding die to feed extrudate against the front perforated surface and through the plurality of non-uniform channels having differing lengths and/or differing cross-sectional area, of the stranding die.
