ABSTRACT:
A component, for moulding glassware, is produced by forming a first mould, for moulding a first metal, placing an insert or inserts of a second, reinforcing metal within the first mould, casting the first metal in the first mould about the insert or inserts, and machining the casting to the desired final shape. The first metal may be cast iron, and the second metal may be a nickel cobalt alloy. The first moulds are designed so that the flow path of the first molten metal does not impinge directly on the second metal whereby the insert is prevented from being prematurely melted.
