Abstract

In a metal casting process a foam pattern (15) is embedded in the sand followed by discharge of hot metal into the casting mould, followed by cooling and removal of the cast metal block. The foam pattern incorporates a metal combined gas outlet and cooling body (1). The body is a fine-porous gas permeable plug embedded within the foam pattern. The body (1) removes heat and decomposing gases. The cooling body is directly adjacent to the casting chamber and has a negative form (3) in the adjacent space for the item to be cast. The assembly has a number of fine porous gas release and cooling passages operating in conjunction with a fluid coolant circuit (11, 13). The maximum diameter of gas passages is 20 to 500 . Also claimed is the use of the casting process for the manufacture of components designed by CAD/CAM process. Further claimed is the use of the process for selective laser sintering of powder material.
