Abstract

A liquid catalyst is vaporised and then injected with a compressed gas (air) into a foundry mould in a first period of a working cycle, the subsequent period being used to flush the catalyst throughout the mould using just compressed gas. The compressed gas fed to the mould is heated and vaporisation of the catalyst occurs during a period between injections in a shut-off zone of the apparatus.
