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.

A tooling for use in a method for electromagnetic welding of two contacted surfaces of molded parts. The tooling includes a rubber body and pressurizing means for pressurizing the rubber body and applying pressure to the contacted surfaces. The rubber body includes an embedded stiff body shaped such as to define different rubber body thicknesses in different directions, which causes a different pressure build-up in the different directions. A method for manufacturing the tooling. The tooling may be used in electromagnetic welding of two contacted surfaces of molded parts by moving a joining inductor along the contacted surfaces, generating an electromagnetic field in an induction-sensitive component of the molded parts to heat a thermally activated coupling means of the molded parts to above a melting temperature of the coupling means.

A method for manufacturing a composite member, in which a composite member having a high joining strength can be manufactured in an inexpensive and efficient way; and the composite member. A metal member and a resin-containing member are joined together by heating the metal member while pressing the resin-containing member against a metal porous film formed on a surface of the metal member. The porous film is formed by impacting the surface of the metal member with metal powder by the cold spray process.

A thermoplastic composite welding microwire temperature measurement system broadly comprises a plurality of moveable antennae configured to transmit interrogation signals, a rail system including a motorized linear stage configured to move the antennae along a weld line, and a reader or processor configured to determine a position of the microwire temperature sensor and determine a welding temperature based on response signals of the sensor. The interrogation signal corresponds to two different maximum ramp current amplitudes to create two re-magnetization pulses non-overlapping in the time domain.

A method of sealing reinforced packages. The method can comprise moving an open-ended package in a downstream direction on a package conveyor by engaging the open-ended package with a chain flight of the package conveyor moving in the downstream direction. The method further can comprise forming a bag with a closed end by engaging at least a seal portion of a tail section of an open-ended tube portion of the open-ended package between the chain flight of the package conveyor and a hot plate positioned adjacent the package conveyor. The chain flight can move with the tail section in the downstream direction relative to the hot plate, which can transfer thermal energy to the tail section to at least partially form a seal along the seal portion in the tail section to at least partially form the closed end of the bag.

The invention relates to a method for the ultrasonic welding of two plastic components using a sonotrode, wherein the energy for the welding is introduced into the plastic components via at least one or more pins of the sonotrode, wherein the two plastic components are welded to one another step by step, wherein the respectively subsequent step of the welding is carried out in a region which has already been loaded and relieved of tension as a result of the preceding step of the welding.

There is provided a polymer fabrication method for forming 3-dimensional shapes from a sheet polymer blank (10) by machining at least one re-entrant, elongate groove forming a reduced thickness portion (25) permitting the blank to be folded and having opposed edges (12) at the surface, folding the blank about the groove to form at least a portion of the 3-dimensional shape, the re-entrant of the groove forming an elongate chamber (21) adjacent the reduced thickness portion and opening through an elongate gap (20) between the opposed edges, hot air welding the opposed edges across the gap with filler rod (22), and heating the reduced thickness portion to a selected thermo-reforming temperature via the chamber.
