Sand Core Making Process For Moulding
Sand Mold
Foundries have started to use printed sand as part of a hybrid moulding process, which is part printed cores and part conventional moulding. Fig. shows a part of a complied mould package in which a 1piece printed core replaced a 10piece core assembly along with a conventional phenolic urethane. In this case, the printed core was 10% less than the combined cost of conventional cores ...
