A method is disclosed for additively manufacturing a composite structure. The method may include coating a continuous strand with a matrix, discharging a composite tubular structure made from the coated continuous strand, and exposing the matrix in the composite tubular structure to light to cure the matrix during discharging. The method may also include depositing a material layer onto an internal surface of the composite tubular structure as the composite tubular structure is being discharged, and wiping a squeegee over the material layer.

An extruder assembly has a frame with upstream and downstream ends. A barrel assembly on the frame has a passage. At least one material advancing component resides at least partially within the passage and is configured to be turned around an operating axis to thereby cause material to be conveyed from a passage inlet to a passage outlet. A drive assembly turns the at least one material advancing component around its operating axis and has a motor on the frame situated so that at least a part of the motor is in lengthwise overlapping relationship with the barrel assembly. The drive assembly is configured to turn the one material advancing component around its operating axis at a speed of at least 300 rpm.

A ram extrusion apparatus including a die having several thermal zones, a hopper for introducing a granular polymer resin to the die, and a ram for moving the granular polymer resin through the thermal zones of the die and out from an outlet end thereof at a temperature above the crystalline melt temperature of the polymer resin. The hopper may be designed to deliver the polymer resin into a resin inlet of the die in a plurality of specifically metered amounts which may vary across a width of the resin inlet end of the die. The apparatus may further include one or more finishing tables positioned after the outlet end of the die for receiving and moving the extruded resin away from the outlet end of the die so that there is no backpressure on the extruded resin, and which provide compression force and even cooling to the extruded resin.

An extrusion apparatus to sheathe wires, semi-finished products for cables, or stranded wires. The extrusion apparatus includes an extrusion head and a motorized adjustment device. The extrusion head includes a molding die and a semi-finished product guide having an aperture. The semi-finished product guide and the molding die are arranged with respect to each other so that a molding compound can be formed into an extruded molded product through the aperture of the semi-finished product guide via the molding die. The motorized adjustment device is moved by an actuating signal. The motorized adjustment device is assigned to the semi-finished produce guide and/or to the molding die so that the semi-finished product guide and the molding die can be aligned with respect to each other by moving the motorized adjustment device via applying the actuating signal.
