This disclosure relates to the manufacturing of a leading edge section with hybrid laminar flow control for an aircraft. A manufacturing method involves: providing an outer hood, a plurality of elongated modules, first and second C-shaped profiles having comprising cavities, and an inner mandrel; assembling an injection moulding tool by placing each profile on each end of the inner mandrel, arranging a first extreme of each elongated module in one cavity of the first profile and a second extreme of the module in another cavity of the second profile, both cavities positioned in the same radial direction; and placing the hood on first and second profiles to close the tool. Further, the injection moulding tool is closed and filled with an injection compound comprising thermoplastic and short-fiber. Finally, the compound is hardened and demoulded.

A passive horn integrally formed using thermoplastic vulcanized rubber includes a first outer casing, a second outer casing, an inner casing and an iron piece. The first outer casing includes a sealing ring, a folding ring and a vibrating membrane, and the sealing ring, the folding ring and the vibrating membrane are integrally injection molded into the first outer casing. A groove is disposed in the second outer casing, and the first outer casing is disposed in the groove. The back surface of the vibrating membrane is provided with a casing groove sequentially embedded with the inner casing and the iron piece. Furthermore, a preparation method of a passive horn integrally formed using thermoplastic vulcanized rubber, which, under the condition of integrated injection molding, may improve the yield rate, ensure product quality, save assembly time and labor cost, and improve production efficiency.

A pack case includes: a first wall pressing a battery stack toward a second side in a stacking direction; and a second wall pressing the battery stack toward a first side in the stacking direction. At least one of the first wall and the second wall is a panel structure wall including a first metal plate, a second metal plate located outward of the first metal plate in the stacking direction and faces the first metal plate, and an interposed member interposed between and fixed to the first metal plate and the second metal plate. The interposed member has a lower density than a metal forming the first metal plate and the second metal plate.

A composite gear includes: a first member comprising a rotation shaft portion and a disk-shaped web extending in radial directions from the rotation shaft portion; and a second member comprising at least one engaging tooth on an outer periphery thereof and provided being supported by the web so as to surround an outer periphery of the first member. A space is provided between the second member and an outermost peripheral surface of the first member in a radial direction, a space is provided between the first member and an innermost peripheral surface of the second member in a radial direction, and at least one of the first member and the second member is formed to nip another of the first member and the second member from both sides thereof in an axial direction of the rotation shaft portion.

A pipe sealing gasket is shown which is designed to be received within a raceway provided within the female, belled end of a section of plastic pipe which is assembled with a mating male pipe end to form a plastic pipe joint. The gasket is a two-component gasket having a softer, elastomeric portion and a harder, plastic ring portion. A splicing technique is used to form the softer, elastomeric portion with the harder, plastic portion being injection molded over the previously formed elastomeric portion.

A method of forming at least one channel within a substrate includes coupling a fitting to a mold, and securing together the fitting and an insert via threads. A system includes a mold configured to form the substrate. The method also includes inserting a component into an opening of the fitting. Part of the component is disposed outside of the opening of the fitting, and the component is utilized to define the at least one channel within the substrate. The method further includes molding at least one material to the component and the insert to form the substrate. Furthermore, the method includes removing the fitting from the insert while the insert remains molded to the substrate.
