A blow mold assembly is disclosed having removable neck insert mold components for forming features of a container for engaging a removable container closure and manually operable retention devices for releasably retaining the neck insert mold components with mating mold components of the mold assembly. Advantageously, each manually operable retention device includes a clamp mechanism movable between a release position and a clamp position by manual operation and the clamp mechanism is effective to resist forces acting on the clamp to move the clamp to a release position when the clamp is in the clamp position. Each manually operable retention device is retained with an associated mating mold component when a neck insert mold component is removed from or installed to the mold assembly.

A method for producing a half shell for a hollow body includes applying a preheated plastics sheet to a first tool half that forms a die, and then pre-stretching the plastics sheet, at least in certain regions thereof, by blowing or suctioning away, at least certain sections of the plastics sheet from the first tool half. The plastics sheet is then suctioned or pressed, via pressure or negative pressure, onto the first tool half, at least in certain regions.

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.

A manufacturing process for filler tube includes: a workpiece arrangement step of arranging a workpiece onto an outer peripheral mold not only to axially lock a to-be-locked portion with respect to a locking portion but also so as to make the outer peripheral mold, which is set at a predetermined temperature, support a cylinder-shaped body of the workpiece on the outer peripheral face; and a flare-molding step of flare molding a flange by inserting an inner peripheral mold, which is set at a higher temperature than the predetermined temperature of the outer peripheral mold, into a to-be-molded portion on the inner peripheral side, and by relatively moving the outer peripheral mold and the inner peripheral mold in the axial direction to make a counter-welding-face forming portion and a welding-face forming portion clamp the to-be-molded portion between them in the axial direction.

Provided are a fuel tank made of polyketone and a method of manufacturing the same. The method includes injection-molding an upper cover and a lower cover using an injection-molding machine, placing the upper cover and the lower cover at a relatively high position and a relatively low position, respectively, assembling the upper cover and the lower cover with each other, and bonding contact surfaces between the upper cover and the lower cover to each other using a laser beam. Since the upper cover and the lower cover are formed at the same time and are bonded to each other immediately after being assembled by a machine, it is possible to achieve automated production, mass production and remarkable cost reduction. Further, since the fuel tank has sufficient rigidity due to the rigidity of polyketone without an additional reinforcing member, it is possible to manufacture a lightweight fuel tank.

A method for assembling a box structure includes elementary parts assembled along an understructure of stiffeners and skins. The understructure and skins are made of composite material with a polymer matrix. The method includes sizing the box structure for the loads to which it is subjected and for a glued assembly. A map of the loads on the structure is obtained and a first load limit is defined depending on the probability of the structure being damaged. The understructure and the skins are assembled by gluing them. An additional layer is applied that covers the assembled elementary parts to areas of the assembled box structure where the first load limit is reached.

A fuel tank for a motor vehicle, which can be designed as a blow-molded hollow plastics tank, into the interior of which a functional component support is inserted, to which are fastenable functional components, for example a fuel pump, a level indicator or valves, and which is supported on opposite inner sides of the fuel tank wall via at least two strut arrangements spaced apart from each other in a longitudinal direction of the support. The functional component support has at least one compensating portion which is positioned between the two strut arrangements and with which a length compensation between the functional component support and the fuel tank takes place in order to dissipate mechanical component stresses.

A fuel tank and a method for producing a fuel tank for a motor vehicle. The fuel tank is designed as a blow-molded hollow plastic member, into the interior of which a functional component support is introduced. The support, to which functional components, such as a fuel pump, a level indicator or valves can be secured, includes at least one supporting leg to be supported on an inner face of the hollow plastic member delimiting the interior thereof. The supporting leg of the functional component support is designed to include a connection point to which a functional component can be connected.

A process for manufacturing a hollow body including a thermoplastic wall and a fibrous reinforcement welded on at least one portion of the surface of the wall, or its outer surface, the fibrous reinforcement including a thermoplastic similar to or compatible with that of the wall of the hollow body, having a thickness of at least 1 mm and from 30 to 60% in weight of fibers, the method including heating a portion of the outer surface of the hollow body where the reinforcement will be welded; heating the fibrous reinforcement to soften or melt the thermoplastic of the reinforcement; and moving the reinforcement and applying the reinforcement to the portion of the outer surface of the hollow body. The applying the reinforcement includes: applying an initial pressure on at least one portion of the reinforcement; and applying pressure for a final welding using robotized pressure applying mechanism.
