In this study, the analysis of the influence of the pouring temperature on manufacture process of castings by the Lost Foam method was introduced. In particular, numerical simulation results of effect of silumin and grey cast iron pouring temperature on pouring rate and gas gap pressure were analyzed. For simulating investigations of the Lost Foam process introduced mathematical model of the process was used. For calculations, the author's own algorithm was applied. The investigations have proved that with increasing pouring temperature the pouring rate increases, while pressure in the gas gap are decreasing. The author's own investigations showed a more significant effect of the silumin pouring temperature than grey cast iron pouring temperature on the lost foam process.
