Abstract

A method for molding powder under compression by use of a compression molding machine including a horizontally supported turntable provided with bores vertically extending therethrough, and upper pressure rods and lower pressure rods respectively positioned above and below the respective bores, the upper end portion of each lower pressure rod being fitted in the corresponding bore. The method includes subjecting powder contained in each bore to preliminary compression by dropping the corresponding upper pressure rod into the bore by gravity before the compression molding operation. <IMAGE>
