Abstract
A control unit for a powder material compression molding machine including a powder material compressor which compresses a powder material filled between compressing members in an adjusted filled amount by making the compressing members approach to each other at a predetermined interval, so as to mold a molded product, and a pressure detector which detects a powder material compressing pressure by the powder material compressor. The control unit including a weight determiner which determines that the weight of filled powder material is normal, a thickness determiner which determines that the thickness of the molded product is abnormal in the case where the pressure detected by the pressure detector falls out of a first predetermined range when the weight determiner determines normality, and a compression controller which controls the powder material compressor when the thickness determiner determines abnormality.
