Professor Schwam and Zhu explained that the earliest reports on squeeze casting originated in 1878
Russian literature, the reports suggested pressure should be applied to molten metal while it solidifies
in a mould. The commercial development of squeeze casting began to take place in Europe, North
America and Japan only after 1960. Two types of squeeze casting technology have evolved based on
different approaches to metal metering and metal movement during die filling. These have been named
direct and indirect squeeze casting.
