There are three forms of energy transport: conduction (diffusive transport), convection (heat transmitted by the mechanical motion of the fluid) and/or radiation (through space). All three are active during solidification of a casting. Energy diffusion and convection occurs within the casting, at the metal/mold interface, and within the mold. Energy is transported by radiation from the mold to its environment, which is typically the air.
