摘要: An injection rate (cm3/sec) of a screw feeder at the time of starting an injection is the largest and the injection rate (cm3/sec) thereof gradually or sequentially decreases until an end of injection so that a temperature of a melted resin reaching the end portion of a cavity decreases within a range where the melted resin is not solidified.
