A fuel tank includes a tank body and a built-in component, which has a head portion, a neck portion, and a shoulder portion, the built-in component being anchored to the tank body with a parison wrapped around the neck portion during molding of the tank body. The head portion and the neck portion are formed with at least one hollowed portion, which is open to an end surface of the head portion, and a cap member is provided to seal an opening of the at least one hollowed portion.

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.

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.

This method for manufacturing a pipe (2) for a vehicle fuel tank involves—molding 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, then—cutting off the end portion of the wall.

An Arrangement for transporting media, comprising a base body formed as a blow-molded part and at least one functional element, wherein the functional element is positively fixed to the base body, wherein the positive fit is formed by shaping the base body during blow molding, and a method for producing an arrangement.

A method for manufacturing an arrangement for the transport of media includes a base body formed as a blow-molded part and at least one functional element, in which a preform consisting of polymeric material and at least one functional element are provided and arranged in a blow mold, wherein the base body is formed from the preform, wherein the preform bears against the functional element during forming, wherein the blow mold has a first mold element and a second mold element, wherein the base body is formed from the preform between the first mold element and the second mold element, wherein the first mold element and the second mold element bear against the functional element in such a way that excess material produced from the preform in the area of the functional element during blow molding can be removed.

Disclosed is a method for producing at least one molded, filled and sealed container product (10) comprising at least the method steps listed below: extruding a hose (32) by means of an extrusion device (12) using supporting gas in vertical extrusion direction in a preforming position; sealing the hose (32) at its lower end and cutting it at its upper open end; transporting of the parison (22) thus cut to length by means of a gripper device (20) in linear transport direction transverse to the extrusion direction from the preforming position into an opened molding tool (18); transferring the parison (22) into the opened molding tool (18) by means of the gripper device (20) in a main forming position; sealing the molding tool (18) for further forming of the parison (22) by a pressure gradient; filling and sealing the parison (22); and returning the gripper device (20) to the preforming position for a repeated sequence of the above method steps

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.

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.
