Semisolid Casting of Product with Thin Fins by Using Al-25%Si

Abstract:

Low solid fraction simple rheocasting using Al-25%Si is proposed to cast a product with thin fins. The characteristics of this casting are presented. A conventional die-cast machine was used. The low solid fraction semisolid slurry was made in the sleeve of the die cast machine. Super cooling was used to reduce the casting temperature. The huge latent heat of the Si was utilized because of its excellent flow ability. A model of a heat sink, which was 0.5mm thick, 25mm high with 0.5 mm draft angle, was could be cast by the proposed process.
