ABSTRACT:
While a die cast product is produced by a die casting method, an overheated portion of a low pressure die casting metallic pattern is effectively cooled by circulating a cool air and/or a coolant. Therefore, a solidification period of a molten metal in a cavity is minimized, and a quality of products and a durability of the metallic pattern are improved.
