| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a molding method by which a product can be inexpensively produced in a simple manner.SOLUTION: The molding method comprises the steps of: producing ice particles by adiabatic expansion, in which the ice particles having a particle size smaller than the particle size of metal fine particles are more than the ice particles having a particle size larger than the particle size of metal fine particles; mixing the produced ice particles and the metal fine particles; temporarily cooling and storing the metal fine particles and the ice particles; injecting into a mold, the metal fine particles and the ice particles which are cooled and stored; and taking out the metal fine particles and the ice particles from the mold and treating the metal fine particles and the ice particles at normal temperature or higher. |
