An injection molded composite component includes a groove extending from a first surface of the composite component and a tubing material placed within the groove and formed integrally with the composite component such that the tubing material forms an integrated conduit on the first surface of the composite component.

A joining structure includes a first member, a second member of a material different from that of the first member, and a separation mechanism provided between the first member and the second member and that separates the first member and the second member from each other, wherein a resin is filled into the space between the edge of at least one member among the first member and the second member, and the other member.

A plastic faucet body and a die for molding the same are disclosed in present invention. The plastic faucet body comprises a left water inlet pipe (1) and a right water inlet pipe (2), wherein a connecting cross-beam (3) is disposed between the left water inlet pipe (1) and the right water inlet pipe (2), the left water inlet pipe (1) and the right water inlet pipe (2) are embedded with a threaded copper pipe (4), respectively, the copper pipes (4) are formed integrally with the plastic faucet body by means of a single stage process and are in communication with the corresponding left water inlet pipe (1) and the right water inlet pipe (2), respectively.

A machine including a mold which delimits an overmolding cavity, for receiving a hollow portion of a bi-material part, cooling means along the overmolding cavity, a core positionable inside the hollow portion and containing heating means for bringing the core to a heating temperature higher than 150° C., and an injector injecting an overmolding material, formed by the core and the hollow portion, for forming an inner portion of the bi-material part. In order to obtain the overmolded inner portion even if the hollow portion has poor heat resistance, the cooling means maintain the overmolding cavity at a cooling temperature lower than 110° C. while the core is brought to the heating temperature, while the overmolding material has been injected by the injector into the overmolding cavity.

A light-weight gear including: an annular tooth portion made of metal; a shaft extending along a central axis of the tooth portion and made of metal; and a coupling element configured to couple the shaft to the tooth portion and made of a resin, in which a joining part between the shaft and the coupling element and a joining part between the tooth portion and the coupling element are provided with irregularities configured to be engaged with one another in a circumferential direction, and corners of the irregularities are rounded to release a stress. Also, provided is a manufacturing method of a light-weight gear including: disposing the tooth portion and the shaft in a mold and injecting a molten resin into a cavity of the mold, thereby simultaneously performing injection molding of the coupling element and joining the coupling element to the tooth portion and the shaft.

The invention relates to a thermoplastic elastomeric bellow duct (10) having a corrugated duct segment (12) interposed between two elbowed segments (14, 18), wherein at least one of the elbowed segments (18) is made of thermoplastic elastomeric and connected to an end section (22) of the corrugated duct segment (12) by overmolding the elbowed segment (18) over the end section (22) of the corrugated duct segment (12), and wherein the end section (22) of the corrugated duct segment (12) includes a guiding and sealing arrangement (50) pointing away from the corrugated duct segment (12) in a radial direction (32). The invention further relates to an air duct (80) having such a thermoplastic elastomeric bellow duct (10).

A production apparatus of a two-layer preform including an inner layer preform and an outer layer preform includes: an outer layer cavity mold for injection-molding the outer layer preform. A bottom surface of the outer layer cavity mold is provided with a protrusion for separating the inner layer preform disposed in the outer layer cavity mold from the bottom surface.

A method for producing a media-tight material composite, in particular comprising a metal solid body and an optionally electrically insulating plastic at least partially surrounding the solid body, preferably as a component of a preferably shielded electrical interface, wherein surfaces of the solid body that the plastic contacts are subjected to a surface pretreatment in order to promote the adhesion of the plastic to the solid body. The disclosure further relates to a cylindrical metal sleeve, in particular as part of a plug connector, and a plug connector or sensory comprising a metal sleeve, produced by the foregoing method.

A manufacturing method for manufacturing a pipe joint including a circular tube-shaped housing and an elastically deformable circular tube-shaped seal member provided at an inner peripheral side of the housing. The pipe joint manufacturing method includes a process of placing the seal member inside a mold in a state in which the seal member is fitted to an outer periphery of a retaining pin, and a process of causing a molten resin to flow into the mold so as to mold the housing in a state in which the seal member is cooled through the retaining pin.

A structure includes: a first member made of metal having a tubular shape, and having a through-insertion hole; a second member made of resin and joined to the first member; and a third member made of metal having a tubular shape, and inserted through inside the first member. The third member is tube-expanded toward the first member and joined to the first member by press-fitting.
