摘要： A method of producing an insert which is to be embedded in a concrete structure comprises preparing a flexible mold, setting a cylindrical core in the flexible mold, pouring a powdered ceramic material into the flexible mold in such a manner to fully cover the cylindrical core, compressing the flexible mold from the outside to compress the powdered ceramic material thereby to produce a molded green body that holds therein the cylindrical core, removing the molded green body together with the cylindrical core from the flexible mold, removing the cylindrical core from the molded green body proper by turning the cylindrical core in a releasing direction, and baking the molded green body proper to produce the insert. The cylindrical core has a male thread portion formed thereon and thus, upon removal of the cylindrical core from the molded green body proper, the molded green body has a female thread bore portion.
