Japanese Patent JP7025809

B2

To improve utilization efficiency of molds when using the molds to manufacture products containing non-metallic inorganic materials.SOLUTION: The present invention is a manufacturing method of a molded body by performing in order: an injection process of mixing a raw material solution containing powder, a solvent, a dispersing agent and curing resin made of non-metallic inorganic materials with a curing agent so as to be injected into a mold; an in-mold curing process of forming a primary cured body with predetermined hardness by curing, through curing reaction, the mixture of the raw material solution and the curing agent inside the mold; a de-molding process of desorbing the primary cured body from the mold; an out-of-mold curing process of obtaining a secondary cured body having predetermined hardness by advancing the curing reaction of the primary cured body desorbed from the mold; a drying process of drying the secondary cured body; a degreasing process of degreasing the secondary cured body after drying; and a sintering process of sintering the secondary cured body after degreasing. The hardness of the primary cured body is 40% to 70% of the hardness of the secondary cured body obtained in the out-of-mold curing process.SELECTED DRAWING: Figure 1
