Provided are an inlet pipe including a curved portion having a curved shape, and a molding method thereof. In the molding method of the inlet pipe, that one part of the inlet pipe which includes a curved portion having a large curvature is molded by injection molding, and the other part of the inlet pipe except the one part molded by the injection molding is molded by blow molding.

The invention relates to a device and a method for semi-continuous blow moulding of fiber-reinforced, thermoplastic, endless, hollow-profile-shaped components with longitudinally constant or varying cross-sections, consisting of at least one consolidation tool, which, in its closed state, encloses a preform enclosing an elastically moldable pressure chamber.

Method of making a blow molded article from a preform including: a) providing a preform of a thermoplastic material having a plurality of effect structures each having an effect surface having a normal with an orientation, the preform having a body with one or more walls and an opening, wherein at least a portion of the one or more walls of the preform has a three-dimensional pattern of cavities and/or protrusions thereon; and b) blow molding the preform to form a blow molded article, wherein the step of blow molding the preform changes the orientation of the normal of at least some of the effect surfaces of the effect structures to create a visual effect in at least one wall of the blow molded article.

A blow molded monolayer article. The article has a hollow body defined by a wall. The wall has one or more regions comprising a first composition and one or more regions formed by a second composition.

A support device for improving the haptics and/or gripping impression of humanoid or android type hands includes an active surface that interacts with parts (16, 18, 22) of the respective hand to carry out a movement and that has individual stem-like projections. Each projection has a free end face such that the projections at least partially improve the adhesion of at least parts of the hand or a hand protector (10) to surfaces, particularly smooth or delicate surfaces, that are touched. The respective free end faces (26) of the projections (24) are designed such that their adhesion results from acting van der Waals forces between the free end faces (26) and the touched surface.

A generally hollow preform for making a stretch blow-molded container may include a threaded finish portion; a neck portion depending from the finish portion; a transition portion depending from the neck portion; a main portion depending from the transition portion; and a closed, generally rounded tip portion depending from the main portion. The preform may include stretch ratios with respect to the container including an axial stretch ratio of about 3.0 to 3.5, a hoop stretch ratio of about 5.0 to 5.5, and a total stretch ratio of about 15 to 19.25. In some embodiments, high stretch ratios may be achieved with less material, yielding substantial cost savings.

Microstructured composite material, comprising a matrix, comprising at least one sort of a thermoplastic plastic material and, distributed homogenously in the matrix, at least one sort of lignin and/or at least one lignin derivative, characterized in that the at least one sort of lignin and/or at least one lignin derivative is present in particulate form and the cross-sectional area of the particles has a round, approximately round, circular, approximately circular, elliptical or approximately elliptical geometry.

A bioabsorbable composite stent structure, comprising bioabsorbable polymeric ring structures which retain a molecular weight and mechanical strength of a starting substrate and one or more interconnecting struts which extend between and couple adjacent ring structures. The ring structures can have a formed first diameter and being radially compressible to a smaller second diameter and re-expandable to the first diameter. The ring structures can comprise a base polymeric layer. The interconnecting struts can be formed from a polymer blend or co-polymer of poly-L-lactide (PLLA) and an elastomeric polymer. The interconnecting struts each can have a width that is less than a circumference of one of the ring structures. The adjacent ring structures can be axially and rotationally movable relative to one another via the interconnecting struts. The interconnecting struts can also be bioabsorbable.

A process includes contacting a metallic acrylic salt with a polyolefin, forming a polyolefin composition. The process includes extruding the polyolefin composition, and pelletizing the extruded polyolefin composition. A production rate of pellets of the polyolefin composition may be equal to or greater than a production rate of pellets of the polyolefin prior to contact with the metallic acrylic salt without increasing extrusion pressure or motor amperes. The polyolefin composition may have a melt flow rate that is lower than the melt flow rate of the polyolefin prior to contact with the metallic acrylic salt. The metallic acrylic salt may only be contacted with the polyolefin to form the polyolefin composition during a start-up of an extruder and pelletizer.

The invention relates to a method for producing hollow bodies from thermoplastic material by using an at least three-part blow-molding tool with at least two blow-mold halves (1a, 1b), which define a mold impression, have part-cavities (5a, 5b) and can be displaced toward one another and away from one another in the sense of an opening and closing movement, and also with at least one central tool (2), which is displaceable transversely in relation to the opening and closing movement of the blow-mold halves (1a, 1b), the method comprising the extruding or providing and arranging of at least two molten performs (7) of thermoplastic material in web form between the blow-mold halves (1a, 1b) in an opened receiving position, the bringing to bear of the preforms (7) in the part-cavities (5a, 5b) of the blow-mold halves (1a, 1b) and molding of them into shells (10) using sealing elements which are provided on the central tool and are extended from the central tool for the purpose of sealing off the part-cavities before or while the part-cavities are subjected to differential pressure; the joining of at least one insert (9) in at least one shell (10) by using the central tool (2) arranged between the blow-mold halves (1a, 1b) and the joining of the shells (10) to form the closed hollow body by closing the blow-mold halves (1a, 1b) while applying clamping force and, if appropriate, the final blow molding of the hollow body.
