PROCESS AND TOOLING SYSTEM FOR THE MANUFACTURE OF A THIN-WALLED INSULATING STRUCTURE, AND THIN-WALLED INSULATING STRUCTURE OBTAINED THEREBY

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.
