Abstract: A method for manufacturing a high precision hollow metallic component, by obtaining, through extruding or roll forming, a precursor hollow metallic profile having a constant cross section and at least one precursor chamber; positioning the precursor hollow metallic profile in a split-die cavity, wherein at least two walls of said split die cavity have essentially outside dimensions of corresponding walls of the high-precision hollow metallic component; introducing a mandrel made of at least two parts into the precursor chamber; plastically deforming the precursor hollow metallic profile by expanding the mandrel to obtain finished dimensions of the high-precision hollow metallic component; removing the mandrel from the finished chamber after reversing an expanding action. A variable cross section hollow metallic component, with at least two chambers obtained with the method, is also described.
