A bonding device of a fuel cell part is disclosed. The bonding device of the fuel cell part may bond an upper gas diffusion layer and a lower gas diffusion layer to top and bottom surfaces of an MEA base material through adhesive layers, while disposing the MEA base material between the upper gas diffusion layer and the lower gas diffusion layer, and may include: a lower die that supports the MEA base material, the upper gas diffusion layer, and the lower gas diffusion layer to be bonded with each other; an upper die installed in an upper side of the lower die; and an ultrasonic wave vibration source that is installed to be capable of moving in a vertical direction at opposite sides of the upper die, compressing the upper gas diffusion layer, and applying ultrasonic wave vibration energy to the adhesive layer.

A method for producing composite profiles comprises providing a first profile part extending in a longitudinal direction, made from a first plastics material, with a profile region produced from a second plastics material thermally plasticizable at a first temperature, providing a second profile part extending in a longitudinal direction, made from a material not thermally plasticizable at the first temperature, and with a receiving structure formed along the longitudinal direction of the second profile part, with which the profile region of the first profile part is connectible, bringing the profile region of the first profile part into contact with the receiving structure of the second profile part, plasticizing the second plastics material of the profile region by heating to the first temperature and deforming the plasticized profile region while forming a positive engagement between the profile region and the receiving structure while maintaining the geometry of the receiving structure.

A system and a method for stud fixation with the aid of mechanical vibration energy that is applied to the stud and that is used for local liquefaction or at least plastification of a material, which is based on a thermoplastic polymer and includes the stud (at least distal stud end) and/or by the object (at least in a fixation location), wherein simultaneously the distal stud end is pressed against the fixation location of the object. Depending on the material pairing of stud (distal stud end) and object (fixation location), this results, on re-solidification of the liquefied or plasticized material, in an embedding of the distal stud end in the object (e.g. positive fit connection), in a welded connection between the distal stud end and the object, or in a local penetration of stud material into the object (e.g. positive fit connection).

A method of anchoring a connector in a heterogeneous first object that includes a first building layer and, distally of the first building layer, an interlining layer. The method includes providing the first object and the connector, which includes thermoplastic material in a solid state; contacting the connector with the first building layer; applying a first mechanical pressing force to the connector until the first building layer is pierced by the connector and a distal portion of the connector reaches into the interlining layer; applying a second mechanical pressing force and mechanical vibration to the connector until a flow portion of the thermoplastic material is flowable and penetrates structures of the first object, and a distally facing abutment face of the head portion abuts against the metal profile in a region next to the opening; and letting the thermoplastic material resolidify to yield a positive-fit connection.

A method for reducing stress and distortion in a component during a friction welding process includes securing first and second workpieces of the component within an inertia welding machine such that the first and second workpieces are affixed in opposition to each other. The method also includes securing at least one annular support member at least partially around the first workpiece and/or the second workpiece at a location having a reduced cross-section as compared to remaining portions of the first workpiece and/or the second workpiece. Further, the method includes rotating the first workpiece to a predetermined rotational speed. In addition, the method includes engaging the second workpiece with the rotating first workpiece so as to generate frictional heat therebetween, thereby welding the first and second workpieces together. As such, the annular support member(s) supports the location having the reduced cross-section during welding.

Methods and systems are provided for a housing for a fastener of a vehicle component. In one example, a housing for a fastener includes a central conduit adapted to receive the fastener, and a radial key extending outward from an outer surface of the housing. The radial key is first pressed against a vehicle component in an axial direction of the housing to form a first section of a channel within an interior of the vehicle component, and the key is then rotated against the interior to form an undercut, second section of the channel in a circumferential direction of the housing.

The invention relates to an anchor for arrangement in lightweight building boards, wherein a lightweight building board has a first covering layer and a second covering layer made from compact material that is stiff in compression, and a core layer, which is arranged between the covering layers and is made from material with a low density in comparison with the covering layers, in particular paper honeycomb, foam or solid wood of low density, having a first anchor part and a second anchor part, wherein the first and the second anchor part are designed to be movable relative to one another, in which a travel between a first end position and a second end position is limited, wherein the first end position is defined by means of first stop means on the first and the second anchor part, and the second end position is defined by means of second stop means on the first and the second anchor part.

A method for joining two objects by anchoring an insert portion provided on one of the objects in an opening provided on the other one of the objects. The anchorage is achieved by liquefaction of a thermoplastic material and interpenetration of the liquefied material and a penetrable material, the two materials being arranged on opposite surfaces of the insert portion and the wall of the opening. Before such liquefaction and interpenetration, an interference fit is established in which such opposite surfaces are pressed against each other, and, for the anchoring, mechanical vibration energy and possibly a shearing force are applied, wherein the shearing force puts a shear stress on the interference fit.

A method of anchoring a connector in a heterogeneous first object that includes a first building layer and, distally of the first building layer, an interlining layer. The method includes providing the first object and the connector, which includes thermoplastic material in a solid state; contacting the connector with the first building layer; applying a first mechanical pressing force to the connector until the first building layer is pierced by the connector and a distal portion of the connector reaches into the interlining layer; applying a second mechanical pressing force and mechanical vibration to the connector until a flow portion of the thermoplastic material is flowable and penetrates structures of the first object, and a distally facing abutment face of the head portion abuts against the metal profile in a region next to the opening; and letting the thermoplastic material resolidify to yield a positive-fit connection.

The invention concerns a method for joining a metal component and a polymer component, and a structure comprising said components. In the method, an extrusion die plate with a through hole is placed between the metal component and the polymer component. A probe is rotated and plunged across the thickness of the metal component and eventually through said through hole of the extrusion die plate, thereby extruding a part of the metal component through said through hole of the extrusion die plate into the polymer component. The probe has a rotation axis having an offset to the centre of the through hole during the rotating and plunging action.
