Abstract: A lightweight part and process and device of making the same, the lightweight part including an inner core including a metal foam. A dense core surface layer is metallically joined to the inner core. An outer wall includes an essentially pore-free cast metal layer that is at least one of positively engaged with the dense core surface layer and surrounding the inner core, and metallically joined to the dense core surface layer and surrounding the inner core. The process includes creating a core part by forming the dense core surface layer, forming the inner core of a metal foam, and metallically joining together the inner core and the dense core surface layer. The process further includes creating a finished part by positioning the core part in a casting mold, feeding a melt material into the casting mold, and allowing the melt material to solidify so as to form the outer wall.

Abstract: The invention relates to a method for producing a small thin-walled tube for a medical application or for a medical product, in particular for a stent, wherein a blank of an in particular bioresorbable magnesium alloy is deformed to produce a small tube, after which the small tube is used for medical purposes or from which the medical product, such as a stent, can be made. In order to be able to produce the small tube in one step and with high precision, it is provided according to the invention that a male die (2) with a base body (3) and a mandrel (4) tapered relative to the base body (3) and the blank is provided with a blind hole or an opening, wherein a diameter of the blind hole or the opening of the blank is equal to or greater than an outer diameter of the mandrel (4), after which the blank with inserted mandrel (4) with the male die (2) is pressed forwards at least in part through a female die (5) with a receiving region (6) and a contouring region (7), wherein the contouring region (7) has a free diameter, which is larger than the outer diameter of the mandrel (4), but smaller than an outer diameter of the blank, in order to form the small tube.
