An apparatus (1) for performing the above process is also disclosed.

A method of manufacturing magnets and a method of manufacturing a rotor are provided. An intermediate member includes a sheet and magnet bodies. The sheet includes a first sheet surface and a second sheet surface on a side opposite to the first sheet surface. The magnet bodies are located on the first sheet surface. A first die is made of an elastic material having an elastic coefficient lower than the elastic coefficient of the magnet bodies. The intermediate member is arranged between the first die and a second die such that the second sheet surface of the sheet faces the first die. The first die and the second die hold the intermediate member in between. Accordingly, the sheet is cut at positions between adjacent ones of the magnet bodies.

A method for joining at least two joining partners includes performing a plurality of ultrasonic joining operations in direct succession, wherein performing an individual ultrasonic joining operation includes, with a second joining tool, applying pressure to a second joining partner arranged adjacent to a first joining partner, thereby pressing the second joining partner against the first joining partner, and, with the second joining tool, applying high-frequency ultrasonic vibrations to the joining partners. The method further includes, during at least one intermediate time interval between two directly successive ultrasonic joining operations, at least one of actively cooling and heating the second joining tool. The second joining tool is heated or cooled by a temperature unit. The temperature unit is inactive during each of the plurality of ultrasonic joining operations.

A process for welding a first molding to a second molding. The process uses an implement including first and second external surfaces. Each external surface further includes a duct. An end of the first molding is heated by a hot gas while the end is at a distance from the duct-entry plane in the range from 3 mm outside the duct to 10 mm inside the duct. A junction area of the second molding is heated by a hot gas while the junction area is at a distance from the duct-entry plane in a range from 3 mm outside the duct to 10 mm inside the duct. The heated end and the heated junction area are then brought into contact with one another and cooled, forming a weld between the first molding and the second molding. Also disclosed is a welded molding obtainable by the process of the invention.

Method for the production of a pacifier teat and pacifier teat with a suction section forming a cavity, to which suction section a shaft adjoins, wherein an elastic hollow body having suction section and the shaft is pre-formed in an injection or in a dipping process and opposite wall sections of the pre-formed hollow body are connected with each other in the region of the shaft.

A repair method for a workpiece of a plastics material is provided, wherein an induction heating apparatus is positioned at a repair region of the workpiece. The induction heating apparatus comprises a magnetic field generating device and a heat source. The heat source is arranged between the magnetic field generating device and the repair region. A repair material is positioned on the repair region and heated by way of the heat source. The heat source is inductively heated by the magnetic field generating device. A temperature (T) is measured by which an application of heat to the repair material by the heat source is characterized. The temperature (T) is controlled by means of a control device. The control of the temperature (T) by the control device occurs according to a temperature profile specification, which has a heating region and a working region following the heating region.

A steering wheel sheath includes a carbon fiber-comprising composite element and a leather element. The composite element forms a notch and a receiving space axially. Two ends of the composite element extend to form two connection portions bending by a predetermined angle. Inner walls of openings at two ends of the leather element form two engaging portions corresponding in position to the two connection portions of the composite element. An adhesive is applied to outer walls of the two connection portions of the composite element or inner walls of the two engaging portions of the leather element; hence, the composite element and the leather element are connected, coupled and fixed together. The customized manufacturing process allows the steering wheel sheath to be mounted by users and enhances overall feel.

A method for joining at least two joining partners includes performing a plurality of ultrasonic joining operations in direct succession, wherein performing an individual ultrasonic joining operation includes, with a second joining tool, applying pressure to a second joining partner arranged adjacent to a first joining partner, thereby pressing the second joining partner against the first joining partner, and, with the second joining tool, applying high-frequency ultrasonic vibrations to the joining partners. The method further includes, during at least one intermediate time interval between two directly successive ultrasonic joining operations, at least one of actively cooling and heating the second joining tool.

A method of rivet bonding a workpiece stack-up that includes one or more polymer composite workpieces, such as carbon fiber composite workpieces, involves several steps. In one step, adhesive is applied to a surface of the workpiece stack-up. In another step, workpiecesincluding the polymer composite workpiece(s)are brought together. In yet another step the adhesive is partially or more cured. A rivet is installed through the workpiece stack-up and through the adhesive in another step. The method strengthens the resulting rivet-bonded joint by minimizing or altogether precluding fracture, cracking, and/or delamination thereat.

An apparatus for welding composite thermoplastic materials comprises a welding member configured to receive the composite thermoplastic materials there at; and a controller for controlling a temperature by which composite thermoplastic materials received at the welding member are heated, the controller being configured to provide a plurality of heating cycles during which the composite thermoplastic materials are welded. There is also a method for welding composite thermoplastic materials, the method comprises receiving the composite thermoplastic materials at a welding zone; and applying a plurality of heating cycles to the composite thermoplastic materials at the welding zone.
