Latest Patents
One of Hans Naf's latest patents involves a process and apparatus for manufacturing molded parts from granulated materials. This process utilizes a mold with relatively movable parts that enclose a mold cavity, which is fed with plasticizable material. The method includes directing grains of the plasticizable material into a vertically elongated vestibule, which is connected to the feed of the mold cavity. Hot gases are directed into the lower end of the vestibule and upwardly through the plasticizable material, making it weldable. The weldable material is then directed into the cavity under pressure. The device designed for this process features a feed conduit connected to the cavity, which is situated below the vestibule. The vestibule consists of an upper cylindrical zone, a lower cylindrical zone of smaller diameter, and an intermediate frusto-conical zone that interconnects the two. This innovative design allows for efficient feeding of granular material and circulation of hot gases, enhancing the manufacturing process.
