A pressure sensor (27) is inserted into a tip of a heating cylinder (13) of an injection molding device (10). During a measurement process, a little amount of grain-shaped biomass resin (45) and a little amount of powder-shaped additive (46) are supplied from constant feeders (52, 54) to a hopper (40) lying at an inlet (28). Right below the inlet (28), a material is supplied through certain periods of time with an opening left in a space in the heating cylinder (13). A controller (25) calculates a backing power (PJ) of a screw (14) based on a pressure value detected with the pressure sensor (27), and controls a driving unit (18) so that the power multiplied by a coefficient (K) (1.2 ~ 2.0) becomes a driving power (PH) added to the screw (14). |
