With consideration of the viscosity of semi-solid aluminum alloy slurry and filling features

the die casting die for semi-solid aluminum alloy standard samples have been designed and manufactured

in which heating apparatus and ingate cross section with different sizes have been considered. Semi-solid die casting was conducted. The results reveal that without heating on semi-solid die casting die

liquid aluminum alloy can not completely fill cavity

resulting in occurrence of many casting defects. With heating on mould

castings exhibit desirable formability. In the range of cross-section

with increasing in ingate cross section

quality of the castings is improved.
