Abstract

Aluminum alloy port cover was manufactured by counter-pressure casting

and filling and solidification were simulated.The results reveal that the simulated results are accordant with the trial product ones.The mechanical properties of the trial-product aluminum alloy port cover with shrinkage porosity（hole） free

which is manufactured by pressure-reduction types counter pressure casting

are greatly improved

where tensile strength and elongation reach 315～325 MPa and 4%～6%

respectively.
