Abstract

PURPOSE:To produce a multilayered molding with high performance and a simple installation by dividing the inside of dies by means of a partition plate, packing required raw material powders in the respective cavities and retreating the partition plate then molding the powder by pressure. CONSTITUTION:A supporting bar 14 is provided movably in a groove 13 provided in dies for molding, and a partition plate 9 is mounted perpendicularly to the leading end thereof. The leading end of the plate 9 is moved between the faces 15, 16 of a cavity 12 to divide the cavity 12. Raw material powders are supplied and packed in the divided spaces 6, 7, then, the plate 9 is retreated and a feeder 17 is retreated. At this time, the contact surfaces 11 of the respective raw material powders collapse and assume irregularly rugged surfaces. Thereby, the joining strength of both after compression molding and sintering is improved. This method provides its effect in the manufacture of middle-sized and large- sized multilayered moldings having large layer thicknesses.
