1. A manufacturing method for a sintered product made of a plastic molding composition which includes:
a powder containing at least one of a ceramic particle and a metal particle; gelatin; a polar solvent; and a plasticizer that reduces the minimum amount of the solvent necessary to give a flowability to the composition, wherein the plasticizer is a water-soluble or water-dispersible compound, the plasticizer has a ratio of hydroxyl number to carbon number per molecule in a range from 8% to 100%, the plasticizer is in solid or liquid form, and when the plasticizer is in liquid form, the plasticizer has volatility equal to or lower than volatility of water, the manufacturing method comprising: forming a molded product by an injection molding method, an injection molding method, a transfer molding method, a compression molding method, or an extrusion molding method; drying the molded product; and sintering the molded product into a predetermined shape. |
