Apparatus for the injection of a plastic material in a molding process. The apparatus is composed of a cylinder (10) which has a smooth cylindrical anima (12), in which is placed a spindle (14) and in the front end a nozzle (16) is placed with one piece (18) to be coupled to the mold. The spindle is helicidally groooted so that the breasts are greater than the crestas; behind this there is a smooth surface (17) that coupled, as well as the crestas, perfectly to the surface of the cylinder. The material enters an opening in the cylinder (20) and it is advanced and heated through the spindle of the spindle and at the end it is homogenized in temperature and viscosity when passing through the space existing between the spindle and the nozzle.
