Abstract

A method of making a metal shape comprising the steps of supplying molten metal into a ceramic shell mould mounted in a container, spinning the container and the shell mould therein about an axis and permitting the metal to solidify in the shell mould and thereafter removing, for example by breaking, the shell mould to expose the metal shape. The ceramic shell moulds made by providing a pattern of flexible elastically deformable material of a required shape and supported on a mandrel, applying at least one coating of hardenable refractory material to said pattern to form a rigid shell and removing the mandrel from supportant relationship with the pattern and subsequently removing the pattern from the shell by elastically deforming the pattern. The pattern is made by moulding said material in a master mould of a required shape and removing the pattern from the master mould, after the pattern has set, by elastically deforming the pattern.
