CENTRIFUGAL CASTING

Centrifugal casting consists in manufacturing pieces by allowing the molten metal to solidify while the mold is rotating; thus, the metal adheres to the mold´s walls with the centrifugal force from the machine.

  • The rotation and pouring speeds of the metal vary according to the alloy used and size of the pieces.
  • Centrifugal casting machines can be horizontal or vertical.

Horizontal machines are preferred for long and thin cylinders, and vertical machines for rings.

CHARACTERISTICS OF CENTRIFUGAL CASTINGS:

    1) The piece is practically free from defects, with a tight closed grain and homogeneous finish.
    2) No metallic impurities or residues on the piece.
    3) Fewer loss of metal when pouring, compared to conventional sand molding.
    4) Better mechanical properties.
    5) High productivity, meaning a lot more pieces can be cast in less time.
    6) It can be used to produce bi-metallic piping with Babbitt.
