An inductor coil for induction welding of a packaging material having at least one layer of metal foil is disclosed. The inductor coil can be configured to induce an alternating current in the at least one layer of metal foil for inductive heating of the packaging material. In some embodiments, the inductor coil comprises a base layer material and a top layer material bonded to the base layer material to form an irreversible bonding interface comprising a mixture of the base layer material and the top layer material. An induction sealing device comprising at least one inductor coil and a method of manufacturing an inductor coil for induction welding of a packaging material is also disclosed.

Inductor coil for induction welding of a packaging material

The method relates to a method for producing a strand-like, particularly band-like semi-finished part for electrical contacts, wherein the semi-finished part has a top side intended for making the electrical contact, said top side made from a silver-based composite material in which one or multiple metal oxides or carbon are embedded, and has a carrier layer supporting the composite material made of easily solderable or weldable ignoble metal, and method having the following steps: Powder-metallurgic production of a block made from the silver-based composite material, encasing of the block made of the composite material with a powder made from the easily solderable or weldable ignoble metal, compressing the block, encased by the metal powder, to condense the metal powder, sintering the compressed block in a reducing atmosphere or in an inert atmosphere or in a vacuum, avoiding the formation of fluid eutectics from the silver of the composite material and from the non-precious metal with which the block made from the silver-based composite material is encased, reshaping of the sintered block by extrusion pressing, creating a partial strand with a top side made from composite material and a bottom side made from non-precious metal.

Method for producing a semifinished product and semifinished product for electrical contacts and contact piece

The invention relates to a method for producing a strand-like, particularly band-like semi-finished part for electrical contacts, wherein the semi-finished part has a top side intended for making the electrical contact, said top side made from a silver-based composite material in which one or multiple metal oxides or carbon are embedded, and has a carrier layer supporting the composite material made of silver or a silver-based alloy, said method having the following steps: Powder-metallurgic production of a block made from the silver-based composite material, encasing of the block made of the composite material with a powder made primarily of silver, compressing the block, encased by the metal powder, to condense the metal powder, sintering the compressed block, reshaping the sintered block by extrusion pressing, creating a partial strand with a top side made from composite material and a bottom side made from silver or a silver-based alloy.
