s1, filling plastic particles in the injection molding machine, starting the injection molding machine, and preheating the injection molding machine;

s2, starting the injection molding machine, and extruding the residual waste materials in the injection molding machine until the plastic cement is extruded out in a relatively neat manner;

s3, placing the plug power cord which is not subjected to injection molding into the mold, closing the mold, aligning a feed hole of the mold with a discharge hole of the injection molding, and starting an injection molding machine to perform injection molding;

and S4, opening the mold after the injection molding is finished, and obtaining the finished product of the injection molded plug power line.

The above; are merely preferred embodiments of the utility model; the scope of the utility model is not limited thereto; any person skilled in the art is within the technical scope of the present disclosure; the technical scheme and the improved concept of the utility model are equally replaced or changed; are intended to be covered by the scope of the present invention.
