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.

The present invention provides a method for producing molded articles by joining primary molded parts by injection welding, by which a molded article composed of primary molded parts that are joined with high weld strength can be produced. The present invention relates to a method for producing molded articles including a welding step of injecting an injection welding material containing a polyamide around or between butt weld portions of primary molded parts disposed in face-to-face contact, so as to weld the primary molded parts together to form a molded article. The polyamide contains dicarboxylic acid units and diamine units. This polyamide further contains triamine units in an amount of 0.05 to 1 mol % with respect to the total dicarboxylic acid units.

An end effector for an electrosurgical instrument includes a pair of opposing first and second jaw members (2), (3), movable between an open position in which the jaw members are disposed in a spaced relation relative to one another, and a closed position in which sealing surfaces of the jaw members cooperate to grasp tissue therebetween. A first sealing electrode (9) is located on the first jaw member (2), while a second sealing electrode (10) is located on the second jaw member (3). One or both of the sealing surfaces are provided with electrically conductive stop members (12), the one or more stop members maintaining a predetermined spacing between the first and second sealing electrodes when the jaw members are in their closed position. One or more insulating members (14), (17), (19) are present to prevent the conductive stop members from causing an electrical short between the first and second sealing electrodes when the jaw members are in their closed position.

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 molding 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 molding tool is closed and filled with an injection compound comprising thermoplastic and short-fiber. Finally, the compound is hardened and demolded.

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.

Disclosed herein is easy and efficient production of a light and strong resin tube. A resin sheet is molded into a tubular form having a gap, and at least the gap portion is sealed with resin to produce a resin tube. This enables easy and efficient production of a light and strong resin tube.

An overmolded seat back structure having a connecting surface for supporting a support panel and a process for forming a seat back structure via an overmolding process.

A toilet seat includes a body, a bottom plate, and a joining member. The body includes a seating part and a side wall part. The side wall part extends from each of an inner end and an outer end of the seating part. The bottom plate includes a bottom plate part and a protrusion part. The bottom plate part and the seating part face each other. The protrusion part protrudes laterally from the bottom plate part and is configured to be pressed by an end of the side wall part. The joining member joins the body and the bottom plate. The joining member is formed of a filling material poured to closely contact a side surface of the bottom plate part and a non-pressing surface other than a surface pressing the protrusion part on the end of the side wall part.

A structure is injection molded onto a group of panels to form a container. The container has a tray and an injection-molded feature. The tray has a plurality of side panels that extend at least partially around, and at least partially define, a cavity of the container. The tray has a plurality of multi-part flanges with at least one of the multi-part flanges including a lower flange portion and an upper flange portion. The injection-molded feature has band that is injected molded onto the lower flange portion and the upper flange portion. An injection-molded strip extends along and at least partially defines the corner of the container. The strip extends downward from the inner portion of the band in the elongate corner of the container. A tool is also disclosed for forming the container.

A hollow structure for a face mask includes an inner wall, an outer wall spaced from the inner wall to define a hollow area between the inner wall and the outer wall, and a bottom wall that couples the inner wall to the outer wall. A first portion and a second portion together define a closable opening into the hollow area. The second portion is coupled to the outer wall by a bi-stable membrane that allows the second portion to move between (1) a first, opened position in which the second portion is spaced from the first portion to allow access to the hollow area through the opening, and (2) a second, closed position in which the second position abuts the first portion to close the opening.
