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.
