Notes:
Integral foam molding (IFM) is an economical near net-shape technology to producemonolithic castings with solid skin, foamed core and continuous density transition between skin andcore. It was developed for polymers in the 1960s. But it took about ten years to optimize themolding technique and the quality of the polymer integral foam parts to a marketable stage.Meanwhile, polymer integral foam parts are established in a lot of commercial applications. Thesituation is completely different for metals. The first attempts to produce metal integral foam partswere made only a few years ago. A cost effective injection molding technique for magnesiumintegral foam was developed at the WTM-Institute in Erlangen, Germany. The low-cost productionin combination with the integral foam properties low density, high weight specific bending stiffnessand remarkable damping capacity is very promising. At the beginning we produced only parts withsimple shape, for example plates. But if we think about commercial applications, more complexparts with a three-dimensional shape are required. The focus of this paper is on new developmentsconcerning the production of magnesium integral foam parts with complex shape like a casingcover or a door handle
