A compact camera module that contains a generally planar base on which is mounted a lens barrel is provided. The base, barrel, or both are molded from a polymer composition that includes a thermotropic liquid crystalline polymer and a plurality of mineral fibers (also known as whisker). The mineral fibers have a median width of from about 1 to about 35 micrometers and constitute from about 5 wt. % to about 60 wt. % of the polymer composition.

An mixing section for an extrusion screw has an inlet end and an outlet end as well as alternating wiping lands and barrier lands. The wiping lands have a greater helix angle than the barrier lands. The wiping lands and the barrier lands define inlet channels which narrow toward the outlet end and outlet channels which widen toward the outlet end. A helical pattern of mixing channels is cut into the wiping lands and the barrier lands. The mixing channels may be oriented generally at approximately right angles to the wiping lands and the barrier lands. A portion of the extrudate encounters the inside wall surfaces of the mixing channels and changes direction which improves the mixing of the extrudate.

Methods, apparatuses, systems, and techniques relate to an extruder unit for producing preforms with a tube-like wall from a polymer melt and an associated extrusion process. The extruder unit has a receptacle for an exchangeable dispensing tool, it furthermore comprises at least two different and alternately usable profiling devices. These profiling devices have outlet-side fastening structures, which correspond in the various profiling devices and form the receptacle for the exchangeable dispensing tool, so that the profiling devices can be connected alternately to the same dispensing tool. In this way, any dispensing tool, depending on the wish of the customer, can be operated with different profiling devices, in particular, on the one hand, to carry out profiling by mandrel body movement or profiling by nozzle body movement.

Methods, apparatuses, systems, and techniques relate to a tube-forming device for an extruder unit or an extrusion device and a tube-forming process. The tube-forming device comprises at least one shaping sleeve, which is designed to shape a supplied stream of polymer melt from a substantially strand-like cross section into a tubular cross section. The shaping sleeve has a guiding passage embedded in the sleeve wall, such that the guiding passage is a cavity which lies within the sleeve wall and, in the radial direction of the shaping sleeve, is enclosed in a sealed manner with respect to the outer surfaces.

A torpedo for an extruder comprises: longitudinal member (9) which is provided at the periphery thereof with a plurality of thread portions (12) which protrude outwards and which are spaced apart in the circumferential direction; a plurality of sluice blades (19) which are mounted so as to be movable on the longitudinal member and which are partially engaged in apertures (18) of the longitudinal member, the longitudinal member (9) and the sluice blades (19) being provided with complementary radial guiding surfaces (13, 14, 18) which are in contact with each other; and adjustment means (28) for radially displacing the sluice blades relative to the longitudinal member. The sluice blades extend through the spaces between the thread portions, respectively. The thread portions (12) and the sluice blades (19) are provided with complementary radial guiding surfaces (13, 14, 18).

A mixing element for an extruder screw having a width extending in an x-direction of an x-y-z coordinate system, a length extending in a y-direction, and a thickness extending in a z-direction. The mixing element includes a base defining a passage extending along an axis in the y-direction for receiving the extruder screw. Projections extend radially outward from the base and define channels therebetween. The width and the depth of each channel vary along the length of the channel.

A polyolefin material that is formed by solid state drawing of a thermoplastic composition containing a continuous phase that includes a polyolefin matrix polymer and nanoinclusion additive is provided. The nanoinclusion additive is dispersed within the continuous phase as discrete nano-scale phase domains. When drawn, the nano-scale phase domains are able to interact with the matrix in a unique manner to create a network of nanopores.

Provided is a method for producing a resin composition from which can be formed a molded body having excellent tensile elongation and/or rigidity, and more preferably a molded body which stably achieves both high tensile elongation and high rigidity. An aspect of the present invention provides a method for producing a resin composition which contains a first component and a second component, said method comprising a kneading step for kneading the first component and the second component via an extruder provided with a kneading zone that includes a plurality of narrow gap zones in which the gap between a cylinder inner wall and a screw is not more than 2 mm.

A system for the production of carbonized biomass that includes an infeed for accepting biomass feed material and an associated twin screw extruder. A water heater is connected with respect to at least one inlet along a length of the twin screw extruder and a pressure sustaining valve is connected at an outlet of the twin screw extruder.
