  • Centrifugal casting method, centrifugal casting device, hollow casting mold and feed trough forming device
    Patent number: 6880615
    Abstract: A centrifugal casting method is provided for the manufacture of hollow molds and applications of this apparatus and method are provided. A centrifugal casting apparatus has a hollow mold (13) suitable for the centrifugal casting. For the manufacture of cast workpieees by the centrifugal casting method a plurality of mold cavities (14) formed by at least one hollow mold (13) are arranged and driven such that the mold cavities (14) rotate about a common axis of rotation (18). At least three mold cavities (14) which rotate in a single plane are provided.

  • Method for production of an oxidation inhibiting titanium casting mould
    Patent number: 6802358
    Abstract: A method for producing a lost mold for titanium casting from a curable embedding compound. The embedding compound contains at least one oxidizable ingredient, such as zirconium. A model of an object to be cast is prepared from a material which can be melted out of the embedding compound. A mold is shaped by embedding the model in the embedding compound. The mold is cured and the embedding compound melted out by heating and holding the mold at a maximum temperature for a period of time. The mold is actively cooled to reduce the cooling time. Preferred embedding compound compositions and time-temperature profiles are disclosed.
