<p>PROBLEM TO BE SOLVED: To simplify a molding condition, to facilitate and hasten (streamline) setting work, and to always keep constant molding quality.SOLUTION: Successive trial moldings are performed by using successively-combined paired metal molds M1, M2,,,. When trial molding is performed by using the first paired metal molds M1, a predetermined parting open amount Lm is generated between the paired metal molds M1 when a material to be injected is packed, injection pressure Pi and mold clamping force Pc1 are acquired when a non-defective product is obtained, and the acquired injection pressure Pi is set as a molding condition of injection unit 1i side and the acquired mold clamping force Pc1 is set as an intrinsic molding condition of the first paired metal molds M1. When successive trial moldings are performed by using the second paired metal molds M2,,, the parting open amount Lm is generated between the paired metal molds M2,,, the injection pressure Pi and mold clamping force Pc2,,, are acquired when the non-defective product is obtained, and the acquired mold clamping force Pc2,,, is set as the intrinsic molding condition of the second paired metal molds M2,,, in the same manner as the trial molding is performed by using the first paired metal molds M1.</p> |
