    摘要： PURPOSE:To perform compacting to the uniform density over the entire part in the stage of forming parts having different thicknesses in the central part and outside peripheral part with a compacting press, by inserting an inner punch for forming the central thin wall part into the cavity of a lower die, then packing raw material powder in the cavity and pressing the powder with upper and lower punches. CONSTITUTION:An outside cylinder 11 for supplying raw material powder is slidably mounted to the outside of an upper punch 1 consisting of an inner punch 2 and an outer punch 3 which are slidable with each other. The lower punch 6 in a die 4 is lowered, whereafter the punch 2 of the upper punch 1 is inserted into the cavity 18 of the die 4, and the punch 3 is moved upward. The powder supply port 12 provided in the cylinder 11 is exposed from the punch 3, and raw material powder 7 is packed in the cavity 18. The insertion position of the punch 2 is so set that the compression ratio attains the same compression ratio by the punch 3 in this case. The packed powder 7 is compressed by the descending of the punch 1 and the ascending of the punch 6, whereby a green compact 8 of the parts having the uniform density over the entire part and different thicknesses is compacted.
