摘要
The invention relates to a method for making mould cores, wherein green sand is filled into a pressing mould as moulding sand and the green sand is subjected to pre-compression in the pressing mould using a hydraulic press and after the pre-compression is subjected to final compression. In this way, even complicated mould cores can be made perfectly and efficiently from green sand. IMAGE
