The present invention provides a manufacturing device for a dental material, which comprises the steps of: mixing refractories and water with a ratio of 5 : 1.7; molding the mixed mixture by using the crucible manufacturing device; heating the molded crucible for 1 hour and 30 minutes to 2 hours and 30 minutes above the temperatures of 100°C in an electric furnace; drying the heated crucible at room temperature; and plasticizing the dried crucible for 8-10 hours above the temperatures of 1300°C. The present invention has effects in increasing durability and lifespan by evenly dispersing various ingredients contained in a crucible material. In addition, molding and manufacturing efficiency can be improved by easily removing liquid contained in the crucible material. |
