<P>PROBLEM TO BE SOLVED: To prevent unnecessary power consumption, and to reduce a load of a mechanism system by reducing the rotational torque of a measuring servo motor after measurement. <P>SOLUTION: An injection molding machine includes a mold clamping apparatus 20 for opening and closing a die 30, and an injection apparatus 40 for injecting a material into the die 30. The injection apparatus 40 includes a screw 54 that can inject the material into the die 30; the measuring servo motor 61 rotationally driving the screw 54 and adjustable in maximum limit rotational torque; and a control part 70 reducing or converging the maximum limit rotational torque of the measuring servo motor 61 to zero after measuring the material by the screw 54 and before moving the screw 54 toward the die 30 for injection. <P>COPYRIGHT: (C)2013,JPO&INPIT |
