A method of forming a bi-injected closure, comprising the steps of: forming a cap with a top plate and a depending sidewall, in a first injection moulding phase using a first mould part, the cap formed so as to include one or more external sealing areas; changing the first mould part for a second mould part, the second mould part sealing against the or each sealing area on the cap; and forming an outer ring around the cap sidewall whilst the second mould part is sealed against the sealing area/s in a second moulding phase.

A system and method for producing a comestible baked product in complex shapes using cast molding wherein a portion of the interior cavity forms a baking cup which can optionally receive a liner. Embodiments generally include a first part and second part that are configured to be joined together along a seam. When configured, an outer surface is created and an inner surface cavity which creates a contiguous internal hollow space in the form of a three dimensional shape is formed. A portion of this internal hollow space forms a cup. The mold may provide a means for supporting the mold in a special and beneficial baking orientation such as inverted; the cup may be in a form other than circular shape. Other embodiments may include a single piece that is attachable to the rim of a cup of a multi-cup baking pan or to a single stand-alone cup.

A device for moulding at least one bladed part of a turbomachine, including a base, a mould formed from several parts that are interlocked with each other, this mould being applied to the base and first sealing means being mounted between the mould and the base, a bell-shaped dome mounted on the mould and around the mould, this bell-shaped dome being applied to the base and second sealing means being mounted between the bell-shaped dome and the base, this bell-shaped dome being configured to be held clamped against the base and including inner surfaces cooperating by corner effect with complementary outer surfaces of the mould in order to apply a clamping force on the parts of this mould.

Mold including a first shell having a cavity, a second shell having a projection, and an intermediate shell having a projection suitable for being coupled in the cavity of the first shell and a cavity suitable for being coupled with the projection of the second shell. The second shell includes a first injection channel extending from an inlet hole in a side wall of the second shell to an outlet hole in the projection of the second shell. The intermediate shell has a second injection channel extending from an inlet hole in a side wall of the intermediate shell to an outlet hole in the projection of the intermediate shell.

A method for impregnating a fibrous preform by injection or infusion, comprising steps of: —providing a mold having at least two portions, said mold presenting an inlet orifice and a vent orifice placed on opposite sides of the mold; —placing a fibrous preform in a portion of the mold; —placing a thermo-expandable seal in a passage formed between an inside wall of the mold and the fibrous preform, said passage extending substantially along the direction (X) extending between the opposite sides of the mold; —closing the mold; —heating the mold so that the thermo-expandable seal expands and shuts off said passage; and—impregnating the fibrous preform with an impregnation material.

The invention relates to a method for producing a trim part (10) for vehicles, using an injection mold (1), in which an edge of a carrier substrate is formed by the surface cover layer (8) reaching around said edge by means of a lost seal molded to the carrier substrate.

A process for producing a polymeric stiffened sheet-like component, for example a panel, for aircraft construction. Production includes integration of hollow stiffening profiles, for example closed omega stringers, onto a sheet-like component, for example an external skin, where the stringers and external skin are produced from thermoplastic composite material. The stringers are integrated onto the external skin by establishing contact between the stringers and the external skin and melting thermoplastic composite material with exposure to heat and pressure at the areas of contact between external skin and stringers. Melting of the other sections of the stringers is avoided with a pressurized cooling fluid with a temperature significantly below the melting point of thermoplastic composite material, the fluid flowing through the airtight enclosed space in the stringers. Use of closed airtight thermoplastic omega stringers allows integration of the stringers onto the external skin in absence of any flexible tube within the stringers.

A mold for manufacturing a turbomachine fan casing made of composite material, includes a main axis mandrel around which a fibrous preform of a fan casing is intended to be wound; a plurality of counter-mold angular sectors assembled on the outer contour of the mandrel which are intended to close the mold and to compact the fibrous preform wound on the mandrel; wherein a flat seal with a main elongation axis directed along the main axis is arranged between each angular sector, the flat seal being compressed between two adjacent angular sectors, a first angular sector including a sealing portion passing below a lower face of the flat seal while a second angular sector including a sealing portion passing above an upper face of the flat seal.

A covering device for a component space in a tool for producing fiber composite components is a multi-layer pre-fabricated material cloth provided with a gas-permeable, matrix material-impermeable membrane. A gas-impermeable, matrix material-impermeable film is provided. Membrane and film are connected at their circumferential rims to delimit an evacuation space with a flow aid and closed by a matrix material-tight connection. Gas having passed from the component space through the membrane into the evacuation space is evacuated through an opening of the film away from the component space. A contact element arranged at a side of the film facing away from the evacuation space surrounds the opening of the film. It is connected matrix material-tightly to the film. The contact element has a contact surface at a side facing away from the film for attaching the covering device to an inner side of a tool wall delimiting the component space.

A tire mold having moveable elements displaceable to bring the tire mold into an open or into a closed position. The mold comprises upper and lower side members; a plurality of mold segments defining a mold cavity; a vacuum device for removing gas from the mold cavity; and sealing means with closing seal members configured to cooperate with associated cooperating surfaces for sealing the mold cavity by contact with each other. The one or more closing seal members and the associated cooperating surfaces are moveable relative to each other upon displacement of the one or more moveable elements. Said one or more closing seal members are placed in a position in which they are facing their associated cooperating surfaces without contacting them both in a partial closure position of the tire mold and in the closed position of the tire mold when the vacuum device is not activated.
