A control method for an injection molding machine includes deciding a position where the speed of a movable platen is to be changed from high speed to low speed. Over the coasting distance, between high speed (equivalent to V4) and low speed (equivalent to V6), the speed changes smoothly past the decided position in accordance with a function of time, F(T)=V4-(V4-V6) (1-e-T). Decreasing speed at a second decided position, just before the movable platen stops, is in accordance with a function of position s, F(s)=s(VMAX-VMIN)/D+VMIN. VMAX is equivalent to the maximum mold closing or opening speed and VMIN is equivalent to the minimum speed at which moving of the movable platen is guaranteed.
