Skin-bonded threaded inserts may be installed within a sandwich panel by curing the insert in place as the sandwich panel is cured. Skin-bonded threaded inserts may include a collar that is transitioned between a raised position and a compressed position during installation of the skin-bonded threaded insert in the sandwich panel, due to compression of the sandwich panel during curing. Skin-bonded threaded inserts may include one or more flanges that engage one or more skins of the sandwich panel. Such flanges may be positioned between two skins, or between the core and a skin of the sandwich panel to secure the sandwich panel in place within the sandwich panel. Skin-bonded threaded inserts may be positioned within a sandwich panel without the use of potting compound and may engage with the skins of the sandwich panel, rather than relying on adherence to the core for sufficient pull-out and shear strength.

Annular structures formed using composite materials and systems and methods for forming annular structures using composite materials are provided. The composite materials can include fiber reinforced thermoplastic materials. The annular structures include a number of component parts. Each component part can be in the form of a strip of fiber reinforced thermoplastic material that extends around all or a portion of a circumference of the structure. The ends of the component parts can be staggered, so that they a placed at different locations about the circumference of the structure. Methods for forming annular composite structures include wrapping one or more strips of fiber reinforced thermoplastic material having one or more layers about a mandrel, and fusing the strips to form an integral annular structure.

A molding-forming method, a molding mold, and a molding production apparatus with which efficient burrs removal is possible without requiring a large apparatus. A molding production method includes, in addition to a molding being formed inside a mold, burrs formed around the molding are separated from the molding. After formation of the molding, air is blown inside the mold on at least a portion of the burrs formed around the molding to cool the same, a projecting member is projected toward the cooled burrs, and the burrs are separated from the molding. After pressing the burrs toward the projecting member by the air blowing, the burr is pressed toward the mold surface facing the projecting member by projection of the projecting member to separate the burr from the molding.

A thermoplastic pre-container, typically a blow molded piece, is provided to form several hollow bodies. The pre-container is elongated along a central axis and includes a bottom section, an opened section and in-between at least one hollow body section. A plurality of circumferential grooves are provided in a pre-container sidewall, each with a bottom line formed in a virtual plane perpendicular to the axis. The bodies are obtained after cutting the pre-container in a direction transverse to the central axis and severing the end sections. Due to the cutting at several of the circumferential grooves, a top opening and a base opening are respectively obtained for at least two hollow bodies, each opening being delimited by an annular inner rim of a body flange.

A cutting assembly for a tape lamination head that applies a plurality of composite tape segments includes a cutter carriage configured to slide relative to the tape lamination head and adjacent to composite tape in a direction of composite tape movement; and a cutter assembly, carried by the cutter carriage, comprising a cutting blade and a cutting anvil, wherein the cutting blade is configured to cut the composite tape while the cutting carriage is moving at the same velocity as composite tape moving through the tape lamination head.

A method for manufacturing a fiber formed body includes forming a fiber board into a predetermined outer shape while forming a pattern on an outer surface of the fiber board by compressing the fiber board, a forming at least one positioning member by compressing the fiber board, and positioning, relative to a cutoff device, the fiber board using the positioning member, and cutting off a cutoff target part of the fiber board using the cutoff device. In the method for manufacturing the fiber formed body, formation of the pattern during the forming of the outer shape and formation of the positioning member during the forming of the positioning member are simultaneously performed.

A Magnetic Gear Modulator (MGM) of a Concentric Magnetic Gear (CMG) is manufactured by injection molding a modulator cage over angularly spaced apart MGM pole pieces made of a magnetically conducting material. The pole pieces are initially connected by a support ring, or held by a fixture. The modulator cage is preferably a thermally conductive strengthening fiber filled plastic, a carbon fiber plastic, a carbon fiber filled plastic material, a glass material, or a high performance composite plastic molding material. After molding, the outer and/or inner portions of the molding material, and support ring if present, are machined away preferably exposing both inner and outer faces of the pole pieces embedded in the modulator cage. An MGM made using injection molding over a connected support ring and pole pieces reduces cost, and a carbon fiber plastic modulator cage increases strength.

Systems and methods for making a reduced material container (105) are provided that hold a preform (130) adjacent to an open end (165) of the preform (130), stretch the preform (130), close a mold (110, 120) about the stretched preform (175) to form a truncated preform (185), and introduce a pressurized fluid (160) into the truncated preform (185) to expand the truncated preform (185) and form the reduced material container (105). A stretch rod (125) can be inserted into the preform (130) to mechanically stretching the preform (130). The mold (110, 120) accepts the preform (130) at a first end (135) thereof, has an open state and a closed state, and the closed state forms a cavity (140) defining an internal surface (145) having a second end (150) located remotely from the first end (135). A first length (155) is defined by a distance between the first end (135) and the second end (150), the stretch rod (125) mechanically stretching the preform (130) to a second length (170), the second length (170) being greater than the first length (155).

A method for manufacturing a container includes injecting a first material into a first mold to form a top portion of a preform. The first material and a second material are injected into the first mold to form a bottom portion of the preform. The preform is disposed in a second mold. The preform is blow molded into a finished container.

In a method of producing a resin frame member for a fuel cell, a processing die is used. The method includes a processing step of moving an upper die toward a lower die to thereby form an inclined surface on each of side parts of a resin film. In the processing step, shearing is performed while maintaining a predetermined clearance between the lower processing section and the upper processing section and in a state where each of the side parts is at least partially positioned at a cutout so that each of the side parts is inclined downward toward the inside. The cutout is formed by cutting off an edge part of a placement surface that is positioned on the lower processing section side.
