Sätt och anordning att forma föremål medelst superplastisk formning

摘要

This invention relates to a method and an apparatus for forming details by means of superplastic forming the foil or plate being heated to a suitable temperature and being simultaneously exposed to a fluid pressure so that the material is slowly deformed to a predetermined shape. The heating and hence the deformation of the foil or plate takes place locally by guiding a laser beam (17) over the surface of the foil or plate (12).
