A filler tube including a cylindrical body and flange is manufactured using a cylindrical workpiece. A material forms an outermost layer in the cylindrical body and flange of the cylindrical workpiece. Dividable molds move at a first speed upon adhering the cylindrical workpiece onto the site for forming the cylindrical body, thereby giving the cylindrical body a predetermined diametrical thickness; and then move at a second speed being slower than the first speed upon adhering the cylindrical workpiece onto the other site for forming the flange, thereby filling up the flange with the material and other materials for forming the flange over a diametrical range to be welded onto the fuel tank while making the diametrical thickness of the flange greater than that of the cylindrical body.

A diffuser membrane and a method for manufacturing the same are provided. In the method for manufacturing, a first material is heated and extruded to form a base layer and a second material is heated and extruded to form a coating layer. The base layer and coating layer may be extruded substantially simultaneously in a coextrusion process. Accordingly, the coating may be applied to the base layer in a manner that optimizes the bonding between the two layers and provides the ability to control the thickness of the coating layer. Alternatively, the base layer is formed initially and the coating layer is subsequently formed thereover. The first and second materials have differing properties. The first material may comprise polyurethane and the second material may comprise polyurethane and PTFE.

Blow molded components and systems and methods for forming the same are disclosed. The blow molded component may be an air duct, for example, a structural air duct. The structural air duct may include a hollow main body including a first layer of a first material and a second layer of a second material surrounding the first layer. At least one hollow protrusion may extend from the hollow main body and may include proximal and distal portions. The proximal portion may include the first layer surrounded by the second layer and the distal portion may include only one of the first and second layers. The duct may be formed by blow molding a multi-material parison. The first and second materials may have different tensile moduli, and during the molding process the material with the higher modulus may tear and allow the lower modulus material to fill the protrusion.

The present disclosure generally relates to extrusion die systems. In particular, the present disclosure relates to the cyclical extrusion of materials to generate small sized grain features, generally in the range of nanosized grain features, in a tubular or profile shape, in which the individual nanolayers possess pores and/or polymer crystals oriented parallel to the extrusion flow direction and including products with enhanced permeation properties.

A plastic pipe is formed with elevations oriented to be perpendicular to a pipe longitudinal axis on a pipe outer side, with a pipe inner side on which at least one guide element oriented to be parallel to the pipe longitudinal axis is integrally formed, and with a separating element held on the at least one guide element.

An apparatus for producing biobased carriers for dispersal of biological and chemical molecules includes a premixer having a first inlet, a first outlet, a cavity configured for receiving a wet coproduct and a binder through the first inlet, and a stirring apparatus within the cavity for premixing the wet coproduct and binder into a substantially homogeneous mixture; a high shear mixer having a housing, a drive apparatus and a high shear apparatus, the housing defining an opening, the drive apparatus being within the housing and for forcing the substantially homogeneous mixture from the premixer into the high shear apparatus, and the high shear apparatus including a rotor, a stator and a screen covering the opening and being for shear mixing the mixture including forcing the mixture through the screen and out of the housing in the form of nucleation enhanced particles; and an agglomerator having an interior chamber sized and configured to receive the nucleation enhanced particles from the high shear mixer and for transforming the nucleation enhanced particles into substantially spherical biomass pellets.

Coated conductors comprising a conductor and a peelable polymeric coating at least partially surrounding the conductor, where the peelable polymeric coating comprises from 1 to 8 microcapillaries which comprise a low-viscosity filler material. Also disclosed are methods for making such coated conductors.

A sheathed elongated profile, that is, shaped product, is disclosed. The elongated profile may include a main profile body that is at least partially sheathed in a first synthetics component. The elongated profile may also include at least one disposal, that is, protrusion, on the main profile body that is not completely sheathed in the first synthetics component and at least partially sheathed in a second synthetics component. Methods and devices for producing the elongated profile are also disclosed.

A method of manufacturing a flexible pipe that may include directing a first polymer composition through a first manifold and directing the first polymer composition along an outer surface of a metal tubular structure to form a first polymer tubular structure having an outer surface. Additionally, the method may include directing a second polymer composition through a second manifold and directing the second polymer composition onto the outer surface of first polymer tubular structure to form a second polymer tubular structure having an outer surface polymer tubular structure. Further, directing a third polymer composition through a third manifold and directing the third polymer composition onto the outer surface of second polymer tubular structure to form the flexible pipe. The flexible pipe includes a first layer made of the first polymer composition, a second layer made of the second polymer composition, and a third layer made of the third polymer composition.
