An extrusion die with fastener tension adjustment assembly can be formed of a die body that includes a first die body portion and a second die body portion. The extrusion die can have a lip body connected to one of the die body portions using the plurality of fasteners. In one configuration, the fastener tension adjustment assembly has an elongated body operatively connected to each of said plurality of fasteners. The fastener tension adjustment assembly is movable towards and away from the lip body, thereby simultaneously adjusting an amount of force applied to each of said plurality of fasteners. Because the fastener tension adjustment assembly can simultaneously adjust the amount of force on each of the plurality of fasteners, it can eliminate time consuming fastener-by-fastener adjustments on the extrusion die.

An extruder assembly for forming a multi-layered composite is described, the extruder assembly includes an extruder head having a first and second flow passage, a first and second extruder in fluid communication with the respective first and second flow passage, and a splice bar having a first and second passageway extending from a rear side to an outlet side, and communicating flow from the first and second passageway to an outlet die the splice bar further includes a groove located on the rear side of the splice bar and being positioned between the first and second passageway.

The present disclosure generally relates to extrusion die systems. In particular, the present disclosure relates to a specialty pin cam nut designed for the ease of assembly and disassembly of extrusion dies.

An improved rotary head extruder incorporates a twin auger system, in lieu of the typically used single auger, to create random extruded products having a density within the range of about 3.0 to about 6.0 lbs/cu ft. Extrusion using the rotary die system of a rotary head extruder together with the twin auger system allows for a wide variety of fine materials to be successfully introduced into and conveyed within a rotary head extruder to the die assembly, where the materials are cooked to form random extruded products. A transition piece at the downstream end of the augers allows for continuous, uniform flow to the die assembly, where cooking takes place. The random extruded products incorporate formulations with various ingredients aside from the typically used corn meal formulations, having different tastes and nutritional benefits while maintaining the desired bulk density, texture, and crunch of random extruded products.

A wire harness manufacturing method prevents inadvertent deformation of thermoplastic material and separation of thermoplastic material. A predetermined part of an electric wire 91 is accommodated in a through hole of a tubular body formed by connection between a first and second nest members (123, 124) of a nozzle (12), by integrally connecting first and second case body members (121, 122) of the nozzle (12), with the predetermined part of the electric wire 91 therebetween. An approximately tubular covering member (92) covering the predetermined part of the electric wire (91) is molded integrally with the thermoplastic material, by discharging thermoplastic material plasticized by a material plasticizing unit (11) from thermoplastic material discharge orifices (1213) and (1223) in the nozzle (12) to the outer periphery of the electric wire (91), while moving the electric wire (91) and the nozzle (12) relatively to each other.

An extrusion apparatus is provided with a cylindrical die, a core that is placed inside the die, that is able to move relatively to the die in an axial direction of the die, and that forms a flow path for molten resin between the core and the die, a recessed portion that is provided partway along the flow path and that is recessed in the axial direction, and a separator that is inserted into the recessed portion in the axial direction, an insertion position of the separator in the axial direction changing in conjunction with the movement of the core relative to the die, and that cuts the molten resin by means of a portion thereof that extends from the recessed portion into the flow path.

Die plates for polymer extrusion may include a die plate having an entrance face for accepting a polymer flow and an exit face for extruding one or more polymer strands, wherein the exit face including at least one element constructed from polycrystalline diamond. Systems for extruding polymer may include: an extruder, a die plate attached to an outlet of the extruder and having (i) an entrance face for accepting a polymer flow and (ii) an exit face for extruding one or more polymer strands; an array of blades configured to rotate so as to contact and slide along the surface of the die exit face, thereby cutting the one or more polymer strands extruded therethrough; wherein (a) the exit face, (b) the blade array, or (c) each of the exit face and the blade array comprises at least one element constructed from polycrystalline diamond.

A three-dimensional (3D) printing system may comprise a frame; and an additive component(s) configured to couple to the frame. The additive component(s) may comprise a first extrusion unit, a second extrusion unit, and/or a third extrusion unit. The 3D printing system may be a portion of a hybrid computer numerical control (CNC) machining/3D printing system and configured to manufacture a 3D component autonomously from start to finish. The additive component(s) may comprise a heating system including a hot-air blower.

A method is disclosed for dispensing a polyurethane mixture onto a substrate by generating a liquid mixture from reactive component resins; introducing the mixture in an inlet section of a dispensing device so as to advance it towards a planar-shaped outlet slit section, transversely to the advancement direction of the substrate; distributing the mixture along a gap chamber having a cross section diverging towards the outlet slit section; and dispensing the mixture through the outlet slit section, so as to deposit a thin, uniform film onto the substrate. Fractions of the mixture travel equal distances from the inlet section to the outlet slit section, in equal times, maintaining equal average speeds along each section having zones placed all at the same path distance either from the inlet section or from the outlet slit section.
