Sažetak

Problems in the production of metal foams arise from the lack of knowledge in the control of process parameters. The results are frequently uneven and unpredictable variations in the structure and properties of semi products and final products. This paper comprises all production processes for metal foams and the most commonly used processes are described. Production of metal foams is continuously developing and in parallel are being developed the utilization methods of metal foams due to their specific properties. All the positive characteristics of metal foams, which make them suitable for the use in a variety of designs and products, are described in this paper. Benefits of using metal foams as a casting core material are clarified. Technologies for producing metal foam cores, positioning of cores and mould designs are presented. Casting technologies with metal foam cores and applications are described along with samples of aluminium foam cores.
