Hungry feed

In the extruder, the feeding section is not markedly worn by resin fed exceeding the melding capacity, because the sub-feeder suppresses feeding excessive resin, i.e., feeds resin just in time. This concept has been applied to the injection molding. The hungry feed of resin prevents the cylinder and screw from being worn and allows the steam generated in the cylinder to be spontaneously discharged to the hopper.
