PROBLEM TO BE SOLVED: To enhance dimensional stability and appearance of a molded product, and mold a molded product which requires high level precision.SOLUTION: When a specific molding method is used for molding, in which the specific molding method is configured so that a parting open amount Lm being a predetermined gap is generated between a movable mold 2m and stationary mold 2c of a mold 2 in advance during injection filling, and molding injection pressure Pi being injection pressure which allows molding without defect, and molding fastening force Pc being fastening force which allows molding without defect, are determined and set, correction fastening force Pca for correcting the molding fastening force Pc is set in advance, and timing for correcting by the correction fastening force Pca is set based on a threshold to a predetermined monitor physical amount related to the parting open amount Lm. During production, the monitor physical amount is detected, and a degree of the detected physical amount is monitored. When the monitor physical amount reaches a threshold in a period before completion of shrinkage of resin R in the mold 2 since injection filling to the mold 2, the molding fastening force Pc is corrected by the correction fastening force Pca. |
