A screw for a plasticating apparatus has one or more helical flights. A portion of the screw has a plurality of advancing grooves arranged in a noncontinuous helix cut in the screw. The advancing grooves are dimensioned to receive material therein as the material is conveyed through the barrel. The screw has a plurality of noncontinuous cross-cut grooves traversing one or more of the advancing grooves. The cross-cut grooves have a second helix angle greater than the first helix angle and less than ninety degrees; and/or one or more of the cross-cut grooves have a third helix angle of about ninety degrees.

The present disclosure relates generally to an extruder for producing an extrudate. The present disclosure relates more particularly to an extruder including an extruder body having at least one material inlet and an exit opening. A rotatable outlet is coupled to the exit opening of the extruder body and is configured to rotate as the extrudate is expelled from the extruder body.

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.

A plasticating screw is proposed, with a screw channel, which runs spirally around a screw core, is laterally delimited by a flight (1), (2) and has flow elements (3), (4) that are distributed over its longitudinal direction, extend transversely over the screw channel and comprise a deep section (5) and a compression section (6), rising radially in the longitudinal direction. In order to design a plasticating screw of the type mentioned at the beginning in such a way that its length is reduced and good melting characteristics can be achieved even with little energy input, it is proposed that the compression section (6) forms at least one run-up surface (7), which is inclined towards the flight (1), (2) and is adjoined in the longitudinal direction by a plateau (8) for forming the flow.

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 conveyance portion, a barrier portion, and a path are provided at places of a screw main body in which a kneading portion is provided. In at least one of the places, the path is provided inside the screw main body, and includes an entrance and an exit. The entrance is opened to urge the raw materials having the conveyance limited by the barrier portion to increase pressure on the raw materials, to flow in the entrance. The raw materials flowing from the entrance flow through the path in the same direction as a conveyance direction of the conveyance portion.
