The influences of process parameters and vacuum level in vacuum die
casting technology on the density and mechanical properties of ADC12
alloy die castings were studied. Standard die casting tensile testing
specimens were produced on a 650t cold chamber die casting machine
with different vacuum pressures from 5kPa to 100kPa and different casting
pressures from 66.7MPa to 22.7MPa. Other operating conditions were
kept constant. Density, ultimate tensile strength, yield strength and
elongation were measured. The relationship between operating conditions
and casting properties was discussed and the conclusion was indicated
that vacuum die casting is able to improve the property of castings and
reduce the equipment tonnage while maintaining the property.
