Abstract
Efficient in-situ stirring in pressure casting is difficult. Here, the casting die is provided with internal mechanical agitating means which allow homogeneous distribution of the partially solidified phase at temperatures near liquidus and of optionally incorporated reinforcing materials. One form of agitating means is a masher type plate which moves back and forth within the mould.
