Abstract

This is a process for making cores whereby green sand is used as the foundry sand and is poured into a compression mould and the green sand is precompressed using a hydraulic press in the compression mould and is finish- compressed after the precompression. Complicated cores can be made exactly and inexpensively in this way from green sand. Figure 1 <IMAGE>
