Abstract
A molding injection pressure Pi with which a parting opening Lm is formed between a movable moldand a fixed moldduring injection-filling and which allows formation of a good molded article is obtained and set in advance. A molding clamping force Pc that allows formation of a good molded article is obtained and set in advance. During production, a mold clamping device Mc is clamped with the molding clamping force Pc, and an injection device Mi to apply the molding injection pressure Pi as a limit pressure Ps is driven to injection-fill a moldwith resin R. A parting opening detectorthat detects the parting opening Lm is provided. During production, reset control is executed to reset the parting opening detectorto zero if reset timing tr set in advance has come at least on condition that given preparation for injection is completed after clamping. The reset timing is set in a range covering a given period Zs before injection start time and the given period Zs after the injection start time.
