摘要：A resin flow analysis in a die is performed by CAE or the like to obtain a resinpressure curve at a resin inlet port or a resin pressure curve at a nozzle end portion of amolding machine. Injection (air shot) is performed while a nozzle is separated from a die,so that an injection pressure curve Pa to be detected at this time is obtained. From theinjection pressure curve and the resin pressure curve, an injection pressure commandcurve serving as a molding condition in mass production is obtained. The resin pressurecurve obtained by the resin flow analysis is compensated by the injection pressure curvein an air shot for a time lag and pressure loss caused by the mechanical elements of aninjection molding machine, so that molding conditions in mass production can be easilyobtained. In addition, a pressure loss at the nozzle portion is also obtained, so that aninjection pressure command curve is obtained from the pressure loss, the injectionpressure curve, and the resin pressure curve.
