A plastic containing assembly is provided with a container including a containing member, a front reduced section formed with the containing member, and a shoulder between a front end of the containing member and the reduced section; and a hollow, externally threaded adaptor including an outer protrusion put on the reduced section, an inner projection inserted into both the front end of the containing member and the reduced section, a groove on an outer surface of the projection, a filler member between the groove and the protrusion, and an axial passage communicating with an open front end of the adaptor and the projection respectively. An ultrasonic welding machine may apply high-frequency ultrasonic acoustic vibrations to the filler member and melt same to join the shoulder, thereby forming a first joining layer; and melt a joining portion of the reduced section and the protrusion, thereby forming a second joining layer.

A number of variations may include a product that may include a final part that may include a first part that may include a first face and may define at least one through hole and a second part that may include a second face, at least one stake, and at least one energy director that may be disposed between the first face and the second face wherein the first face and the second face may be abutted against one another and the at least one stake may be passed through the at least one through-hole and the first part and the second part have been ultrasonically staked and ultrasonically welded such that an ultrasonically welded interface may be formed between the first part and the second part.

The invention is about an ultrasonic welding-based microfluidic device. It is mainly made of a first element and a second element welded one to the other via at least one structure (10, 10). The structure (10, 10) comprises an elongated welded portion for said welding, a welding channel (12, 12) extending between the first and second elements and along one side of the welded portion, and a draining channel (13) communicating with the welding channel (12, 12) and the microfluidic path (20, 20) of the device. The invention is further about a method of manufacturing such a device.

A gear housing for an epicyclic gear set, the gear housing including a hollow wheel having internal teething and a first front end with a first front-side joining surface; a housing cover having a second front end with a second front-side joining surface for longitudinally axially covering the hollow wheel; and a bonded connection for connecting the first front end to the second front end through the mating of the first and second front-side joining surfaces, at which the hollow wheel and the housing cover are connected to each other by a bonded connection, in particular, by heated tool welding, infrared welding, ultrasonic welding, or rotary friction welding.

The present invention relates to a thermoplastic resin composition, a method of preparing the same, and an injection-molded article including the same. More particularly, the present invention relates to a thermoplastic resin composition having superior vibration welding properties along with ABS-based resin-specific impact resistance, heat resistance, and the like due to inclusion of an ABS-based graft copolymer including a conjugated diene-based rubber polymer having an average particle diameter of 0.25 to 0.35 m; a rubber-modified graft copolymer including a diene-based rubber polymer having an average particle diameter of 0.6 to 10 m and prepared by continuous bulk polymerization; and a matrix resin, and an injection-molded article including the thermoplastic resin composition.

A method of fastening a second object to a fiber composite part including a structure of fibers embedded in a matrix material includes: providing the fiber composite part including an attachment surface, with a portion of the structure of fibers being exposed at the attachment surface; providing the second object; placing the second object relative to the fiber composite part, with a resin in a flowable state between the attachment surface and the connector; pressing the second object and the fiber composite part against each other and causing mechanical vibration to act on the second object or the fiber composite part or both, thereby causing the resin to infiltrate the exposed structure of fibers and activating the resin to cross-link; whereby the resin, after cross-linking, secures the second object to the fiber composite part.

A method of anchoring a connector in a first object, wherein the first object is a lightweight building element having a first outer building layer and an interlining layer, and wherein the connector includes thermoplastic material in a solid state. The method includes: bringing a coupling surface portion of the connector into contact with an attachment location of the first outer building layer; displacing a portion of the first outer building layer at the attachment location with respect to the interlining layer by applying a first pressing force to the first outer building layer and thereby piercing the first outer building layer; applying a second pressing force to the connector and transferring energy to the connector until a flow portion of the thermoplastic material has liquefied and flown to interpenetrate structures of the interlining layer; and stopping the energy transfer and allowing the flow portion to re-solidify.

A custom weld-repair tool, for use in repairing a discrepant weld between workpieces, including an extended portion and a cavity adjacent the extended portions. The discrepant weld includes an insufficient primary portion and the tool is configured to, when the extended portion is in contact with a proximate one of the workpieces, channel welding energy, received at or generated at the tool, to the proximate workpiece via the extended portion, to form or enlarge a weld at a periphery of the primary portion or directly adjacent the primary portion.

Embodiments herein include a system for joining components. The system can include a rotating base platform, a plurality of receptacles mounted to the base platform, and a rotating sonotrode platform. A plurality of sonotrodes are mounted to the sonotrode platform. Each sonotrode can correspond to a receptacle. Each sonotrode can move in a reciprocating motion between a release position distant from a corresponding receptacle and a compressing position proximal to the corresponding receptacle. The compressing position occurs at a first angular position of the sonotrode platform. Each sonotrode is energized at the compressing position.

A composite component for a vehicle has a core layer made from a theiinoplastic plastic foam and at least one cover layer which is connected to the core layer. The core layer has a higher density in one region than the density of the semi-finished core layer. The cover layer formed from a fiber-reinforced plastic is connected in the region of higher density to at least one joining element by friction welding.
