A method of manufacturing a moulded article from first and second moulding compounds includes attaching a first moulding component to a carrier tool, placing the carrier tool and the attached first moulding component in a mould, applying a first moulding process, removing the carrier tool, placing a second moulding component in the mould, and applying a second moulding process to shape the first and second moulding components and bond the first moulding component to the second moulding component. A moulded article is also disclosed.

The present embodiments provide an apparatus for producing a pressure vessel blank, comprising at least one connection element, a multi-part blow-moulding tool, and at least one blowing pin. The present embodiments further provide a pressure vessel comprising at least one connection element, a pressure vessel blank, and a supporting shell connected to and supporting the pressure vessel blank. An aspect of the present embodiments provides a process for producing a pressure vessel blank using an apparatus comprising at least one connection element that enables a shortened time for producing a pressure vessel blank with increased stability under pressure.

A hollow body forming mold includes left and right half molds, a bottom of the left half mold is provided with a left avoidance slot, a bottom of the right half mold is provided with a right avoidance slot, a left bottom slider is disposed in the left avoidance slot, a right bottom slider is disposed in the right avoidance slot, and the left and right bottom sliders constitute a group of sliders. The mold design resolves a difficult problem that a fabrication hole exists during forming of a hollow body with a built-in component by using an existing conventional process The hollow body forming method has the advantages of a short forming period, the high production efficiency, good combination between a built-in component and an inner wall of an fuel tank, and the high location stability.

An apparatus for molding a handle-equipped container is provided. The apparatus has a gripping mechanism section 160a which comprises a first gripping member 161 having a pair of first chuck members 163 for grasping a preform 200, and a second gripping member 162 having a pair of second chuck members 167 for grasping a container handle 20 in association with the action of the first gripping member 161. The apparatus can simultaneously grasp a plurality of the preforms 200 and a plurality of the container handles 20 and reliably transport them to a blow molding section.

A method for manufacturing a plastic fuel tank including: a) inserting a plastic parison including two distinct parts into an open two-cavity mold; b) inserting a core, bearing at least part of a reinforcing element configured to create a link between the two parison parts, inside the parison; c) pressing the parison firmly against the mold cavities, for example by blowing through the core and/or creating suction behind the cavities; d) fixing the part of the reinforcing element to at least one of the parison parts using the core; e) withdrawing the core; f) closing the mold, bringing its two cavities together to grip the two parison parts around their periphery to weld them together; g) injecting a pressurized fluid into the mold and/or creating a vacuum behind the mold cavities to press the parison firmly against the mold cavities; and h) opening the mold and extracting the tank.

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.

The invention relates to a method for producing a tank from thermoplastic material, comprising the following method steps: extruding or providing a hose-like parison composed of plasticized thermoplastic material, and dividing and spreading the parison into two areal extrudate webs, or extruding or providing two parisons in web form, laying-in and molding the parisons in recesses of a multi-part blow-molding tool using differential pressure, wherein the recesses of the blow-molding tool delimit a mold cavity, punching out, or cutting out in a circular shape, at least one opening in at least one shell-like intermediate product, wherein the opening is produced by way of a punching or cutting tool which penetrates through a wall of one of the shell-like intermediate products, wherein in a second separate method step, a first attachment element of a line connection or of a line arrangement is welded, at the mold cavity side, to the wall of the shell-like intermediate product, in such a way that an encircling weld collar of the first attachment element sealingly surrounds the opening, joining the shell-like intermediate products to form a tank, and removing the tank from the blow-molding tool, and connecting a second attachment element, which is complementary to the first attachment element in the context of a plug-type connection, to the first attachment element, wherein the plug-type connection is produced within the contour of the tank as defined by the tank wall.

A resin panel of which contact surfaces of a rear wall to be in contact with another member are made unlikely to deform while reducing the weight of the resin panel. The panel includes a rear wall having a plurality of contact surfaces to be in contact with another member, and a front wall opposing the rear wall with an interval therebetween, the resin panel including a plurality of ribs obtained by indenting parts of the rear wall toward the front wall and welding the parts to an inner surface of the front wall, wherein a wall thickness of the front wall is generally equal to or smaller than a wall thickness of the rear wall.
