Abstract The present invention is a method of loading a desired amount of powder material into a mold which comprises a tubular body having a bore extending therethrough to define a mold cavity. The method comprises the steps of: providing the mold with a lower press core fitted in the lower end of the bore; bringing the mold with said lower press core fitted therein to a powder filling position; displacing the lower press core relative to the mold so as to determine the depth of the top surface of the lower press core from the top surface of the mold; filling an amount of powder material into the mold and strickling off any excessive amount of powder material to the level of the top surface of the mold; pressing at a desired pressure the amount of powder material in the mold to form a powder compact; and displacing the powder compact with the lower press core relative to the mold so as to bring the powder compact to a desired position in the mold.
