Abstract
A distortion sensor is provided on each of a plurality of tie bars and the extension amount of each tie bar is detected by the distortion sensor thereof, whereby a mold clamping force actually applied to a mold is measured. This measurement specifies the part of the mold that first opens and obtains a minimum mold clamping force that does not open the mold in that part. The minimum mold clamping force thus obtained is the minimum mold clamping force that does not open the mold without being influenced by factors such as the shape and the arrangement of a cavity in the mold and the mold clamping force balance of a mold clamping part of an injection molding machine.
