Abstract
Shaped metal parts are produced on a continuous basis from semi-solid metal preforms. The preforms are supported on pedestals which are surrounded by a ring of material which acts as a heat sink to absorb heat from the liquid portion of the preforms to substantially solidify the liquid portion and prevent the preforms from losing liquid to runoff.
