A molding method for making a monolithic component made of C-SMC and internally including a cavity, including preparing a press including first and second half molds and movable side carriages defining a molding space, and placing a core inside the molding space. The core comprises a membrane, delimiting a containing space shaped to form the cavity, and at least one connector engaged with the membrane. The method includes wrapping a charge of material to be molded around the core, fixing the core inside one between the first and the second half molds, and filling the containing space of the membrane with a filling material. After closing the half molds, applying a molding pressure and then emptying the containing space of the filling material and, after opening the half molds, removing the core from the molded monolithic component.

Disclosed are reinforced structures. The structures are comprised of reinforced elements that have continuous fibers embedded in a matrix material. The reinforced elements are combined in a matrix material to form a desired shape of reinforced structure.

A method for producing hollow bodies made of plastics by blow molding or deep drawing using a deep-drawing tool or a blow-molding tool, comprising the extrusion of preforms from thermoplastics, the method comprising a wall thickness control of the preforms, wherein a measurement of the wall thickness of the preforms takes place within the tool on the mold cavity side on at least one reference point of a preform, the measured value obtained is compared as an actual value with a predetermined target value and the wall thickness control is triggered to change the wall thickness of the preform during extrusion or between extrusion cycles depending on the deviation between the actual value and the target value.

A method and apparatus for the formation of double-walled containers with the structure of two integrally connected and adjacent containers extending in the same direction with an air gap between them, stretch-blow moulded as single bodies out of thermoplastic material, and suitable for mass-production. A thermoplastic tubular blank is formed and then heat-conditioned. The heat-conditioned tubular blank is then mechanically stretched longitudinally and blow-formed outwards by gas pressure to conformingly and stretchingly assume the tubular blank to the shape of a first dual-container shaped mould cavity set in order to form a stretch-blow moulded first container integrally connected to a second container, with both containers extending in opposite directions. Next, additional heat-conditioning is applied to further heat-condition as necessary the stretch-blow moulded second container and if deemed an advantage, at least part of the first container. Then at least one profiled inversion piston and a second dual-container shaped mould cavity set are provided along with one or more wall stability devices applied to at least part of the wall surface(s) of either or both of the two integrally connected stretch-blow moulded containers, such that the second container side wall(s) may be inverted at least partially inside-out, while at the same time the second container bottom wall at least substantially does not invert, in order for the second container to become a substantially mirror-image inverted second container extending in the same direction as the first container, and an air gap is formed between the first container and second container.

A flexible film fluid-dispensing device including (A) at least one flexible film liner member having a flexibility property of from 3.6e-10 Nm to 2 Nm; (B) a rigid frame member for receiving the flexible film liner member and for removably holding the flexible film liner member in place during the flow of fluid through the flexible fluid-dispensing device; and (C) a connection means for connecting the flexible film fluid-dispensing device to the outlet feed stream of a fluid production process line; a process of manufacturing the above flexible film fluid-dispensing device; and a process for dispensing a fluid using the above flexible film fluid-dispensing device.

A method for manufacturing a fiber reinforced structure includes the following. A mandrel of a first material comprises a hollow interior and an aperture that allows a fluid to enter the interior. A layer of a second material provided on the mandrel includes an uncured resin and fibers. The mandrel and the layer are placed in a mold cavity formed by a mold. A pressurized fluid is introduced into the interior of the mandrel via the aperture to generate a force acting to expand the mandrel outward. The mandrel is heated so that it becomes deformable and expand outward to press the layer against the mold. The layer is heated so that it cures. The mandrel is then heated to a temperature above its melting point of the first material so that it melts, after which it is removed.

A method of manufacturing a three-dimensional article includes (1) receiving a data file, (2) analyzing the data file, and (3) defining a support structure. The data file defines a hollow three-dimensional article to be formed from a build material. Analyzing the data file includes identifying an opening that converges to an apex along the sequence of layers. The opening is at least partly defined by an inside edge of the three-dimensional article. The support structure is attached to the edge and closes the opening. The support structure includes a structural sheet portion and an interface web portion. The structure sheet portion defines a majority of an area of the support structure except for a boundary contour between the structural sheet portion and the inside edge. The interface web portion closes the boundary contour and defines a weakness contour for removing the structural portion from the three-dimensional article.

The present invention provides a process for producing a blow-molded foam including foamed cells, the process including: kneading a polyolefin-based resin containing a foaming agent mixed therewith in an extruder, and extruding a parison formed of the polyolefin-based resin between split mold blocks from a die slit at an extrusion rate of 700 kg/h or more.
