【Abstract】 AbstractBased on a large number of experiments and investigations, this paper discussed the moulding mechanisms and basic rules of vacuum full-mould process and put forward technological principles and main points of the processA simple vacuum full-mould production line suitable for individual or small series production was set up and some production tests were made. Some practical properties of castings made in this line were given in the paper.更多还原
