    摘要: The invention relates to a shaping tool for the injection molding or injection compression of information carrier disc blanks (11) made of polymethacrylate plastic which is suited as a component of an injection molding or injection compression machine. The shaping tool is comprised of two mold parts (1, 2), whereby one mold part (1) contains a bottom part (8) of a mold with the information data and, together with the second mold part (2), forms a cavity for the one information carrier blank and one sprue bush (4) for a sprue piece (5) in the tool having a concentrically positioned feed orifice (6). In addition, the tool comprises a impact cylinder (9) for shearing the sprue piece (5) and has an ejector pin (10). The invention is characterized in that the injection gap (SP) between the feed orifice (6) of the sprue piece (5) and the information carrier disc blank (11) is less than 0.3 mm. In addition, the cutting gap (SN) between the edge of the impact cylinder (9) and the information carrier disc blank (11) is less than 0.2 mm.

    摘要: (EN) The invention concerns a method for producing a thermoplastic molding material or element, said material or element containing nanometric inorganic particles. In molten state, the thermoplastic is mixed with the nanometric inorganic particles and with a solubilizing agent in a conveyor screw extruder, the pressures and temperatures being adjusted so that the plastic is in melt form and the solubilizing agent in supercritical state. The invention is characterized in that at the output of the extruder, the mixture passes through a slot with a passage less than 20 $g(m)m to penetrate into an expansion zone and the molten material, wherein are incorporated the nanometric inorganic particles, is evacuated, reduced into molding material after cooling or transferred into a molding tool to be molded. The invention also concerns the molding material and the molding elements obtained by this method, as well as the uses thereof.
