Abstract

PURPOSE:To obtain molded articles, by detecting the difference in resin pressure between the sprue, gate and cavity in the mold to detect the temperature difference of resin, and by converting the injection pressure to the holding pressure well in the injection and filling stage of an injection molding machine.
