PROCÉDÉ DE MOULAGE SOUS PRESSION POUR PRODUIRE DES PIÈCES EN ALLIAGE D'ALUMINIUM

摘要

The present invention provides a casting process for aluminum alloy parts. The process comprises the steps as follows: raising liquid; filling mold; increasing pressure; solidifying consisted of at least two stages of different pressure settings; and relieving pressure. The casting process for aluminum alloy parts provided by the present invention can effectively improve the comprehensive performance and production efficiency of the aluminum alloy parts by changing the pressure during the solidification process of casting the aluminum alloy parts.
