Fremgangsmåde og værktöjssystem til fremstilling af en tyndvægget isolering samt dermed fremstillet tyndvægget isolering

摘要

A chamber of a second forming tool(3) located in a first forming tool(1) or a chamber(18) in the first forming tool is filled with a flowable molding material. First and second forming tools are then moved relative to each other so that material is partially purged from the chamber. A thin wall(7) of material remaining between the inner wall(16) of the first forming tool and outer wall(15) of the second forming tool forms the final component. - Molding material may completely or partly fill the chamber. Relative movement of both forming tools(1,3) either purges molding material in the gap between the two tools or may draw a film of the material into the gap. Additional molding material may be added after tool movements. For introducing thin-walled insulation of moldable material into grooves of stator plates in electrical machines stator plates positioned behind one another in the first forming tool create a chamber for filling with moldable material. - Independent claims are included for: - a) a thin walled component of moldable material produced by the claimed process; - b) thin walled insulation of moldable material in grooves of stator plates of an electrical machine; - c) a tool system comprising first(1) and second(2) tools which move relative to each other for production of the claimed thin walled components.
