ABSTRACT:
A process for producing a thin die-cast molded article of an aluminum material having a portion having a thickness in the range of 0.4 to 1.2 mm using a mold having a gate having an opening of 0.2 mm or greater and the same as or smaller than the thickness of the portion of the molded article separated from a gate portion, members constituting the gate having been treated by nitrogenation at the surface. The thin die-cast molded article of an aluminum material can be produced efficiently with excellent flow of the melted metal of the aluminum material through the gate portion.
