A natural consequence of gravitationally induced drainage6 is evident in foamed slabs (Figure 2c), which usually have a gradient in density, pore size, and pore elongation. Moreover, the shearing forces of the conveyor belt lead to diagonally distorted cells in the final product, causing a pronounced effect on the mechanical properties, which become an isotropic.7 To avoid such results, the foam can be pulled off vertically. The foamed material is either used with a closed outer surface (its state upon coming out of the casting machine) or is cut into the required shape after foaming. The high content of ceramic particles can make machining of MMC foams difficult.
