ABSTRACT:
Shaped metal parts are produced on a continuous basis from a semisolid metal preform. A plurality of freestanding metal preforms are sequentially heated in an induction heating zone to the semisolid level and transferred without substantial deformation or heat loss to a press where they are shaped in a semisolid state into a shaped metal part.
