PROBLEM TO BE SOLVED: To enable a sprue section resin being fed to the rear section (the root section of a screw) of a heating cylinder to always be favorably engaged with (involved in) the screw in an injection-molding machine system in which the sprue section resin having been taken out from a die is fed to the rear section of the heating cylinder under the shape as it is. SOLUTION: This injection-molding machine system feeds the sprue section resin under the shape as it is to the rear section of the heating cylinder, and reuses the sprue section resin as a material resin. In the injection-molding machine system, a sprue section feeding means which feeds the sprue section resin having been taken out from a die for each molding cycle to the rear section of the heating cylinder with the smaller diameter section of the sprue resin as the head is installed.
