Abstract
Shaped metal parts are produced on a continuous basis from semi-solid metal preforms. Plurality of cans, each containing a metal preform, are sequentially heated in an induction heating zone to bring the preforms to a semi-solid level. The preforms can be transformed without loss of any metal or heat to a press where they are shaped in a semi-solid state into a metal part. The can can then be removed and recycled.
