A covering and a method of forming a covering for a hatch door or lid, e.g., the hatch door of a marine vehicle, such a boat or the like, is provided. The covering includes a central portion having a configuration corresponding to a configuration of the hatch door and a thickness. A flange projects from the central portion and has a thickness less than the thickness of the central portion. The flange movable between a first position wherein the flange lies in a first plane generally parallel to a first surface of the central portion and a second position wherein the flange is generally perpendicular to the first plane and defines a cavity in the covering for receiving the hatch door therein.

Provided is a microfluidic film including a base film, a microchannel, which is formed on the base film and through which a fluid flows, and a through passage, which is configured to pass through the base film and through which the base film stacked on an upper portion or a lower portion of the base film and the fluid communicate with each other.

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.

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 mold die includes: a mold die body that is configured to hold an object to be molded, the object including a substrate and a chip mounted in a central area of the substrate, and that has a cavity which is rectangular in a plan view and which is configured to receive a resin material, the mold die body including: a pot for containing the resin material; a gate disposed at one side of the cavity and configured to allow the resin material to flow into the cavity; and a flow-path restricting mechanism that is disposed on both lateral sides of the cavity that are perpendicular to the one side and that is configured to narrow lateral flow paths, the lateral flow paths being flow paths for the resin material flowing through the cavity in which the chip is not disposed.

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.

An open/close counting device to be attached to one of a first die and a second die which constitute a die, the die being opened by relatively moving the first die and the second die, the open/close counting device counting the number of open/close times of the die. The open/close counting device includes an open/close detecting section provided so as to face a target face of the other of the first die and the second die and to detect relative displacement of the target face along a die moving direction in non-contact condition, and includes an output section to output the open/close times counted based on detection of open/close by the open/close detecting section.
