PCT No. PCT/JP91/00738 Sec. 371 Date Nov. 29, 1993 Sec. 102(e) Date Nov. 29, 1993 PCT Filed May 31, 1991 PCT Pub. No. WO92/21504 PCT Pub. Date Dec. 10, 1992.An injection compression molding machine (1) has a clamping unit (10) for positioning an upper mold (15) with respect to a lower mold (16), and an injection unit (30). When the upper mold (15) moves to a specified, slightly open position, a screw (61) of the injection unit (30) is advanced to start the injection of molten resin. When the screw advances to a specified position, the screw speed is decelerated to a specified speed. In addition, when the screw advances to a predetermined stop position, the screw is stopped and the injection rate of molten resin is simultaneously reduced and the molten resin is kept pressurized until the gate (71) is closed.
