PURPOSE:To correspond to disturbance such as difference and variation in powder quality, etc., and to obtain sufficient strength by directly detecting the molding pressure of rolls and adjusting only the supply amount of powder. CONSTITUTION:The molding pressure corresponding to a strength requirement of a molding object is considered as a measured value of pressure 36. Regarding the control deviation to an input signal 38, the number of revolutions of a supply means of powder 30 is operated by the control performance of a controller 34 to control the supply amount of powder and working force is generated by the compression corresponding to the powder characteristic in compression molding to make it possible to obtain a molded object having a desired strength. |
