  • Method of and device for rotary casting
    Patent number: 6715535
    Abstract: A method of casting has a mold assembled on a base plate. The finished mold is rotated by approximately 180° around a horizontal rotational axis. A casting container with an upwardly positioned aperture end, removed from the mold, is filled with melt for one casting operation. The casting container is sealingly coupled by the aperture end to the ingate end of the mold. The mold, together with its contacting casting container, is rotated by approximately 180° around a horizontal axis. Accordingly, the melt reaches the mold, and the casting container is removed from the coupled position away from the mold.

  • Method of and device for controlled quenching light metal castings in a liquid bath
    Publication number: 20010054460
    Abstract: A method of controlled quenching of light metal castings in a liquid bath has castings in the liquid bath subjected, from below, at least temporarily, by a rising flow of gas bubbles. The gas bubbles are generated in situ in a uniformly distributed way at the base of the liquid bath.
