ABSTRACT:
The invention relates to a mould assembly including a plurality of individual moulds. The mould assembly of the present invention is made by separately transfer moulding a starter base 16, a plurality of moulds 12, a downpole 14 and pouring cup 19, providing each with mechanical locking features, such as screw threads, and joining them together into the assembly. Much greater flexibility is thereby achieved in materials and wall thicknesses, which can be different in different parts of the assembly to suit strength and heat transfer requirements, individual bits can be replaced, and the transfer moulding produces a compact homogeneous ceramic structure.
