Abstract
An apparatus for cold injection molding of glass fiber reinforced composite materials. The apparatus includes an injection unit for the composite material, a unit for the mixing of said material, the discharge orifice for the mixed material of which is connected directly with the feeder orifice of the injection unit, and a die or the like for injection of the material into the cavity of the heated mold. The unit is designed so as to discharge a sheet of the elongated material from the orifice of the cavity, in the joining plane of the mold. The dimensions of the sheet are smaller than or equal to those of the piece to be molded. The die and the mold are equipped with guillotine blades to cut the sheet at the end of the injection.
