As a kind of high forming and high precision liquid forming technology, the method is one of the main directions of near net forming technology in the future. V Casting performance by the general effect as the sand casting process, the strength of aluminum alloy casting needs to be further improved. Nagano, Japan National University of science and technology and Japan ASUZAC Group in the original Compared to the original casting process based on, through the use of containing water in silica sand to make sand casting, aluminum alloy castings of the resulting increase in the tensile strength of casting, aluminum alloy castings of maximum tensile strength The tensile strength of aluminum alloy casting obtained by casting process is increased by about10% Casting technology domestic development present situation casting technology domestic development present situation casting technology domestic development present situation casting technology domestic development present situation Twenty century Seventy In the late 1990s, Cao Wenlong and other first to track the Japanese VTechnique method One thousand nine hundred and eighty-three Year Group Co. Ltd. has pioneered the introduction of new company set The production method of high manganese steel penetration fork, then I owned more than ten companies imported from Japan and Germany Casting equipment and technology In recent years, through the digestion and absorption of foreign advanced technology and experience, the domestic The research and application of casting method has entered a new stage, The application of the method is also more and more extensive.
