To perform a foam molding work even by an unskilled person by individually storing set conditions in a foam molding step in a memory by digitally setting, calling the conditions from the memory at each time of altering the conditions, and foam molding under the called conditions.

Conditions, setting time and the like are digitally input regarding all steps, and stored in a memory. Thus, all the set conditions of a mold 1 are input. Similarly, all and detailed correcting items of an incorporated mold are input, an environmental setting is finished, and then an actual foaming operation is started. The mold 1 of a foam molding S to be intended to be molded is mounted at a foam molding machine. A mold number of the mold 1 is input to call its data from the memory. When the operation is started, the operation is conducted according to the set conditions. Thus, if the set conditions can be called, the form molding can be executed as set with good reproducibility even by an unskilled worker.
