A method and an apparatus for manufacturing an aluminum die-cast product are provided, wherein an occurrence of shrinkage cavity is eliminated or reduced to a very small amount, and a sound and high-quality aluminum die-cast product having no casting defect can be produced. The method for manufacturing an aluminum die-cast product by performing die casting while a part, in which a casting defect tends to occur due to solidification shrinkage of a melt, which has been pressure-filled in a mold, during a solidification process, is pressurized with a local pressurization pin includes the steps of allowing the local pressurization pin to follow the movement of a solidification interface based on a solidification interface movement speed, which is calculated in advance, of the melt and keeping pushing the local pressurization pin in until the solidification is completed.
