To achieve universal welding of thermoplastic workpiece parts with simple equipment, an infrared light transmission welding method is disclosed in which simple polychromatic, incoherent infrared light is generated by a simple infrared light source and is directed through a first workpiece part to a weld point for the purposes of connection to a second workpiece part. In particular, the infrared light is directed through a transparent bracing element.

The invention relates to a method by which stitch openings in the area of a seam in a plastic skin (10), in particular a PVC or TPU skin, are sealed, said PVC or TPU skin being provided for a foamed part. Foamed parts of this type are used especially as interior fitting parts, e.g. as a dashboard, in the field of automobile manufacturing. The invention further relates to a PVC or TPU skin comprising a seam of said type.

A rotary impulse sealer for forming a series of discrete bonds in a bondable material. The rotary impulse sealer has a roller rotatable about an axis. The roller has a roller body and a plurality of seal bars extending radially outwardly from the roller and spaced apart around the roller body. At least one of the seal bars has a body and a selectively heatable heating element extending along at least a part of a length of the seal bar body. The roller is rotatable through a pre-heating pressure application region in which the at least one seal bar is adapted to apply pressure to a bond area of the bondable material, followed by a heating region in which the at least one seal bar is adapted to heat the bond area, the regions being stationary with respect to the rotation of the roller. A method of forming packages containing fluid or fluent material includes continuously providing at least two sheets of bondable material having a fluid or fluent material therebetween, applying pressure to a transverse bond area of the bondable material to force the fluid or fluent material away from the transverse bond area, and heating the transverse bond area to form a seal.

A method for manufacturing a metal-clad laminate sheet including forming a laminate sheet having the thermoplastic liquid crystal polymer film and the metal foil bonded together; and providing the laminate sheet with a heat treatment which satisfies conditions (1) and (2) below: (1) a heat treatment temperature ranges between 1° C. inclusive and 50° C. exclusive higher than a melting point of the thermoplastic liquid crystal polymer film. (2) a time for the heat treatment ranges from one second to 10 minutes.

A method for producing a vehicle component from a fiber-reinforced plastic including providing a skin panel having an inner side, outer side and mounting portion. The skin panel is a fiber-reinforced thermoplastic material. At least one stiffening component has a connection surface. The stiffening component is a fiber-reinforced thermoplastic material. The stiffening component and skin panel are contacted wherein the connection surface lies on the mounting portion. The method includes areally warming a joining zone so the stiffening component and skin panel are welded together. The joining zone is cooled. A determined geometry of the combination of stiffening component and skin panel is compared with a predefinable geometry. The joining zone is re-warmed, deforming the stiffening component and the skin panel, and the method includes cooling in order to attain the predefinable geometry if the determined geometry deviates from the predefinable geometry.

The present invention relates to a method for producing a container which consists of a thermoplastic at least to some extent and comprises at least a first compartment element and at least a second compartment element joined to the first compartment element in a joining region by thermoplastic welding. The invention also relates to a plastic container which can be, and preferably is, produced according to said method.

Methods of bonding substrates are provided, including forming a thin film of a metal oxide on a bonding surface of both or either of a pair of substrates, at least one of which is a transparent substrate, and contacting the bonding surfaces of the pair of substrates with each other via the thin film of the metal oxide.

The present invention relates to a method for the automated production of a workpiece having at least one diaphragm, including a workpiece for an electrochemical sensor, including providing a workpiece that has a wall with at least one continuous opening through the wall, wherein a diaphragm body is affixed in the at least one opening, such that the diaphragm body completely fills a cross-section of the opening, and processing the diaphragm body by means of a laser.

To stably produce a laminate wherein heat resistant resin layers are laminated on both surfaces of a fluorinated resin layer, by thermal lamination. A process for producing a laminate, which comprises a preliminary heating step of heating, while conveying by a metal roll 33 for heating and a metal roll 32 for thermal lamination without pressing in the thickness direction, a temporary laminate wherein heat resistant resin films 2 and 2 are laminated on both surfaces of a fluorinated resin film 1 containing a melt-moldable fluorinated resin (A) having at least one type of functional groups selected from the group consisting of a carbonyl group-containing group, a hydroxyl group, an epoxy group and an isocyanate group and after the preliminary heating step, a thermal lamination step of pressing the temporary laminate in the thickness direction, while heating it by metal rolls 31 and 32 for thermal lamination at a thermal lamination temperature of at least the melting point of the fluorinated resin (A) ant at most 420 C., for bonding.
