  • Patent number: 4967826
    Abstract: A process for producing metal parts in accordance with the principle of squeeze or forge casting wherein a permanent mold (2) is provided having a mold cavity, a seal (4) is placed on an upper edge flange (5) of the mold surrounding the cavity opening (6), liquid metal (9) is introduced into the cavity, an upper die (3) is inserted (7) into the cavity such that the level of the liquid metal is raised until the higher-level cavity created by the seal (4) is filled, the metal is at least partially solidified, and the final shape of the part is produced by pressing (9) in the upper die, with deformation and spreading of the seal. The result is a completely dense workpiece of excellent dimensional stability which has the texture of a forged part and is correspondingly of very high strength.
