A method for producing a damper for an air line of an internal combustion engine includes the following steps: providing a temperature-controlled inner part having passages; producing a tubular preform of an outer jacket from a thermoplastic melt; and attaching the temperature-controlled inner part to a blowing mandrel of a blow mold, which is open. The blowing mandrel has outlet openings and the passages are positioned over the outlet openings. The method further includes bringing the temperature-controlled preform over the inner part and closing the blow mold such that the preform is blown against the walls of the blow mold, whereby an outer jacket is obtained. Simultaneously, local connections between the inner part and the outer jacket are obtained by pressing the preform and the inner part against each other in some regions. Finally, the blow mold is opened and the damper is removed.

The present disclosure provides a container and a process for producing the container. In an embodiment, the process includes placing a sleeve bag on valve assembly (SBoV) in a blow mold apparatus. The blow mold apparatus has two opposing and movable molds. The SBoV has a valve seat. The process includes extending a parison of flowable polymeric material around the SBoV and between the opposing molds. The process includes moving the opposing molds to a closed position and pressing an upstream portion of the parison against the valve seat. The process includes blow molding a downstream portion of the parison into a container-shape within the closed mold. The process includes forming a container with the valve seat melt bonded to a neck portion of the container.

A fuel tank has a built-in component with a head portion, a neck portion, and a shoulder portion, and has the built-in component anchored to a tank body with a parison wrapped around the neck portion during molding. The fuel tank includes a deformation prevention structure configured to prevent a wrapping parison portion wrapped around the neck portion from being deformed due to pressure acting on the tank body. The deformation prevention structure is configured to include one of a stepped portion provided in the shoulder portion, a convex portion, and a recess.

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

A method for producing a tube arrangement (1) for the transport of tempering medium, in which base body sections (6, 7) are provided, which have congruently configured separating surfaces (8), wherein at least one functional element (3) on at least one base body section (6, 7) is arranged in such a way that it can be in contact with the tempering medium, whereafter the base body sections (6, 7) are joined along the separating surface (8) and bonded to one another to form the tube arrangement (1).

A composite preform including a preform and a plastic member in close contact with the outer surface of the preform is made by preparing the preform made of plastic material and arranging the plastic member to surround the outer surface of the preform. Subsequently, the composite preform is heated and inserted in a blow molding die and undergoes blow molding in the blow molding die, by which the preform and the plastic member of the composite preform are inflated integrally and a composite container is obtained.

The invention relates to a plastics pipeline comprising at least one pipeline end (1) and at least one support ring (2). It was the underlying object of the invention to improve a plastics pipeline of the type described at the outset in such a way that the support sleeve or the support ring (2) remains firmly connected to the pipeline even in the event of the plastics pipeline being stored in the presence of high air humidity and temperature. This object is achieved by virtue of the fact that the blow molded pipe section (1) runs through the support ring (2) and, as viewed radially, is pressed from the inside outward against the support ring (2), wherein the pipe section (1) engages around the support ring (2), such that the support ring (2), with its outer surface, and the pipe section (1), with its outer surface, are substantially in alignment.

The present disclosure is directed toward a composite balloon comprising a layer of material having a porous microstructure (e.g., ePTFE or expanded polyethylene) and a thermoplastic polymeric layer useful for medical applications. The layers of the composite balloons become adhered through a stretch blow-molding process. Methods of making and using such composite balloons are also described amongst others.

A base made from plastic material for a motor vehicle tank accessory, including protrusions to be welded to a preform during production of the tank by blowing the preform, wherein: the base includes a solid surface recessed from the protrusions, the solid surface including a part without protrusions and a part taken up by the protrusions, the area of the part of the solid surface without protrusions is at least equal to one times the area of the solid surface taken up by the protrusions, the height of the protrusions relative to the solid surface is between 0.6 mm and 0.8 mm.

Pipe arrangement for transporting temperature control media, comprising a base body which is produced by means of blow molding and from which at least a first channel and a second channel are formed, wherein the first channel and the second channel have a first orientation towards one another in a first section and a second orientation towards one another in a second section, wherein the first orientation is different from the second orientation.
