PURPOSE: To provide 6 power molded parts with which stable quality is obtainable regardless of undercut positions of the powder molded parts.

CONSTITUTION: The loads of an upper punch 18 and a lower punch 16 at the time of compression molding are detected by a load sensor 1 for the upper punch and a load sensor 2 for the lower punch. The positions of an upper die 10 and a lower die 12 at the time of packing the material powder are adjusted to eliminate the load difference of both punches 18, 16 at the time of the next molding, by which the amt. of the powder to be packed is adjusted.
