Definitions
- Object of the present invention is to improve a metal molding or a method of the type mentioned so that the opportunities given by the functional insert elements are optimally exploitable and that even a solid, foam-free outer wall area made of metal with a wide range of arbitrary design is possible ,
- each insert element may be one or more parts and preferably substantially flat, but not necessarily flat.
- This insert element or these insert elements have a melting point which is above the maximum temperature reached in the production of the metal molding, and preferably contain steel, another metal or another alloy or else ceramic or other materials, in particular fiber materials made of carbon, glass , Silicon carbide, alumina or other ceramic fibers.
- an insert element consist of aluminum alloy or aluminum, wherein it preferably has coated or glazed surfaces and / or an aluminum alloy having a melting point which is higher than the maximum temperature achieved in the production of the metal molding.
- An insert element is preferably a net, a grid, a perforated sheet-like element, in particular a perforated sheet metal, a wire or fiber braid or consists of a plurality of substantially parallel straight or curved bars. It has openings or interspaces whose shape and / or size are selected so that, although the liquid metal, substantially no foam or its gas bubbles can pass through the openings or spaces.
- the insert element therefore forms a boundary between a metal foam region and a further region in which the metal has fewer or smaller or substantially no cavities.
- Fig. 1 is a schematic representation of a shaped metal body 10 with a metal foam region 12 and a solid wall portion 14.
- an insert member 16 is arranged in the boundary region between the metal foam region 12 and the solid wall portion 14.
- the insert element 16 is preferably a net, grid or braid of metal wire or strand of any cross-section or of carbon or other fibers, a perforated sheet or other sheet or an array of preferably substantially parallel bars or wires of any cross-section.
- the insert element 16 is made of aluminum or another metal or an alloy or a other material having a melting point higher than the melting point of the metal of which the metal foam region 12 and the solid wall region 14 are formed. Steel in different qualities is particularly suitable because of its high strength, its high melting point, its good availability, its low price and the variety of processing and processing options.
- the insert element 16 may have coated or glazed surfaces.
- the example shown thus serves a metal moldings, as above with reference to the FIGS. 1 and 2 represented as a lost core. Its size and arrangement defined the wall thicknesses of the outer wall body 34.
- the metal foam area 12 supports the outer wall body, thereby increasing the rigidity of the metal shaped body and absorbing structure-borne sound.
- a foamable metal is provided, for example, by melting a finished alloy or producing it directly in the liquid state.
- the foamable metal preferably comprises composites with light metal such as aluminum or magnesium.
- the molten metal may be added with particles consisting of a material having a melting point higher than the melting point of the metal (such as SiC or Al 2 O 3 ). These particles serve in particular for the stabilization of the subsequently produced metal foam. Details are given in the patent literature mentioned in the introduction.
