We have developed new Semi-Liquid Metal Casting process. The characteristics of this process are as follows. (1) The alloy slurry is formed during cooling from molten state in shot sleeve (Billet less process) (2) The castings show good mechanical properties (high strength and high elongation) (3) Low Oxide film contamination due to planar flow molten metal supply to shot sleeve by electromagnetic pump poring system. (4) The parts we applied are Front Lower Link and Rear Upper Arm for Middle-class automotive (3.0L). In this paper, the outline of the process and several characteristics of the castings are presented. Compared with some other casting methods The castings which made by this process are able to apply T6 heat treatment(the range of solution treatment temperature is 530〜540℃). And they also show good weldability.
