Abstract: An apparatus for the simultaneous casting of multiple components using a directional solidification process includes; a pouring cup arranged on a centreline, an array of moulds encircling the pouring cup and centre line, an array of feed channels extending from the pouring cup to a top end of each mould, and a heat deflector. The heat deflector comprises a wall arranged between the array of moulds and the centreline extending along the length of the moulds and in thermal contact with the moulds.
