Abstract
Process for the injection molding of a composite article comprising a pair of sections of injection moldable materials, different from each other and integrating along a predetermined welding line, characterized by comprising: the practice, in a mold by injection of said article and for escape of the materials, from a grooved path that starts from the entire length of the linear region of the molding cavity in which said welding line must be located, with which they are determined in that molding cavity a pair of hollow sections corresponding to the respective sections of the article; the practice in the mold of a pair of injection steps for the respective materials to be molded, each of which is opened in the respective hollow section, at a certain distance from said linear region; the simultaneous injection of said materials, in conditions of being molded, into the molding cavity through the respective injection steps, thus forcing the materials to run, in their respective hollow sections, towards each other and both towards said linear region, until they come into mutual contact, still in molding conditions, and, at least, until both materials overflow their sections of the molding cavity and, through and throughout that linear region, reach the escape route grooved, then solidifying the materials in the mold cavity and removing the molded article from the mold.
