ABSTRACT:
Shaped metal parts are produced on a continuous basis from a semi-solid metal perform. A plurality of free-standing metal slugs are sequentially heated within an arcuate path defined by a pair of concentrically-positioned solenoid coils to a semi-solid state, such that they may be shaped into a metal part. Means for rotating the slugs during their movement through the arcuate path is also provided.
