Abstract

A nozzle (250) for extruding a composite material (110) from an extruder barrel (120B). The nozzle includes a body (251) and a tapered nozzle passage (252) extending through the body. The tapered nozzle passage having a nozzle inlet opening (253) configured to interface with the extruder barrel, and a nozzle outlet opening (254), where the tapered nozzle passage has a contoured nozzle passage surface (255) extending between the extruder barrel and the nozzle outlet opening with smooth transitions (270), free of angles, so that each nozzle passage surface portion (255A-255F), having a corresponding contour, transitions smoothly to each other nozzle passage surface portion, having a respective different contour, from the nozzle inlet opening to the nozzle outlet opening, and the nozzle outlet opening is defined by at least a first edge (254A) and a second edge (254A) that intersect each other at an acute angle (¸).
