Mixers are disclosed for the processing of one or more materials to be used, for example, in conjunction with injection molding breaker plates. The disclosed embodiments include the use of multiple integral flow channels having non-linear flow paths that vary in their radial, angular, and axial directions. The cross-section of the flow channels can also vary the nature of distributive and dispersive mixing. A method for the design of the mixers is also disclosed. The use of multiple stages of mixing is also disclosed.

A system for depositing a composite filler material into a channel of a composite structure includes an end-effector configured to extrude a bead of the filler material into the channel. The filler material can comprise a first group of relatively long fibers, a second group of relatively short fibers and a resin. A drive system is configured to move the end-effector relative to the channel, and a position sensor is configured to detect the position of the bead relative to the channel. A controller is configured to operate the drive system in response to the detected position and to operate the end-effector to heat and compress the filler material so as to orient the longer fibers in a substantially longitudinal direction relative to the channel and the shorter fibers in substantially random directions relative to the channel when the bead is extruded into the channel.

The invention relates to a multi-layer, preferably co-extruded, plastic film with improved modulus properties, which is suitable, in particular, for producing three-dimensionally shaped articles.

An extrusion forming apparatus includes an extruding section, a chamber drum, and a forming section. The extruding section kneads a material including a ceramic raw material and extrudes a kneaded material. The chamber drum has a first space portion having a first extruding direction extending portion through which the kneaded material is allowed to flow in an extruding direction, and a second space portion which has a second extruding direction extending portion extending in the extruding direction and a direction changing portion bending from the extruding direction to a downward direction, to allow the kneaded material to flow in the downward direction changed from the extruding direction. The second space portion has a cross section obtained by isotropically decreasing a cross section of the first space portion perpendicular to a flow-through direction of the kneaded material. The forming section has a die to extrude a ceramic formed body.

A system and a method for controlling an extrusion line of mixed plastics, wherein a temperature of one or more heaters of the extrusion line is measured by one or more first sensors; a temperature and pressure of an extruder head is measured by one or more pairs of second sensors; a coolant temperature of a set of dies is measured by one or more third sensors; an amperage of an extruder motor is measured by an ammeter; a pulling speed of a pulling unit is measured by a tester; and wherein a computing device configured to receive the measurement data from the one or more first sensors, from the one or more pairs of the second sensors, from the one or more third sensors, from the ammeter, from the tester.

An extruder for a three-dimensional additive printer can be used to receive and dispense material. The extruder can include a number of different components including a nozzle with an adjustable opening configured to discharge material. The nozzle can be configured to be moved and rotated so as to align the adjustable opening with a plurality of paths along which the material is configured to be deposited for generating a three-dimensional object. The adjustable opening can comprise a first orifice and an obstruction member configured to move with respect to the first orifice. The position of the obstruction member can adjust the size of the opening area of the adjustable opening.

A thermoplastic composite structure is produced by extruding a bead of composite material to a desired cross sectional shape. An extruder extrudes the polymer bead containing reinforcing fibers, using a low compression first extruder stage where the polymer is mixed and de-gassed, and a high compression second stage where the polymer is consolidated and extruded. The cross sectional profile of the polymer bead may be altered using a variable extruder gate.
