A liquid vehicle tank (1) having a wall made of a plastic material, the tank (1) comprising a component (3, 5) affixed to the wall, the component (3, 5) having a portion (10) embedded in the wall, the embedded portion (10) having an external surface (21) a part of which is chemically incompatible with the plastic material of the wall, wherein the tank (1) also comprises a strengthening element welded to the wall over the embedded portion (10) of the component (3, 5).

First, a composite preform 70 including a preform 10a and a plastic member 40a in close contact with the outer surface of the preform 10a is made by preparing the preform 10a made of plastic material and arranging the plastic member 40a to surround the outer surface of the preform 10a. Subsequently, the composite preform 70 is heated and inserted in a blow molding die 50 and undergoes blow molding in the blow molding die 50, by which the preform 10a and the plastic member 40a of the composite preform 70 are inflated integrally and a composite container 10A is obtained.

This method for manufacturing a pipe (2) for a vehicle fuel tank involvesmolding a wall, comprising an inner layer (6) made from ethylene vinyl alcohol (EVOH) and an outer layer (8) made from a polymer suitable for welding, in a mold comprising at least one female shoulder that creates at least one male shoulder on an outer surface of an end portion of the wall during molding, thencutting off the end portion of the wall.

A method of forming a headrest assembly includes providing a first mold that encloses a first cavity in a closed condition. A support is positioned in the first cavity. A first material is blow molded into the first cavity and around a portion of the support to form a core part. The core part and support are removed from the first mold. A second mold encloses a second cavity in a closed condition. The core part and the support are placed into the second mold in an open condition. A fluid is injected into the core part through the support. The second mold is converted to the closed condition. A second material is injection molded into the second cavity and around the core part to form an outer shell around the core part. A fluid is withdrawn from the core part through the support.

Disclosed is a hollow molded article which has an opening portion communicating with a flow channel and which can be manufactured simply. The hollow molded article includes a panel and flow channels. The panel includes a first resin sheet and a second resin sheet partly welded with the first resin sheet. The flow channels are disposed between the first resin sheet and the second resin sheet, and include connection portions for external connection which are disposed on a peripheral edge of the panel. The connection portions are formed by the first resin sheet and the second resin sheet.

A method for manufacturing a glass with a stem or with a base made of a plastic material, the glass including a receiving portion mounted over a base or over a stem, the method being implemented by a rotary tooling comprising a plurality of workstations and at least one mold wherein the method includes the following steps: a) forming of the receiving portion of the glass on at least one first workstation called injection station; b) overmolding of the stem or of the base over the receiving portion, in order to form a glass with a stem or with a base, the overmolding being carried out on at least one other workstation called overmolding station; c) ejection of the glass thus formed on the overmolding station or on another workstation called ejection station.

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.

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.
