No, die casting is not a subtractive process. It is an additive manufacturing process where molten metal, such as zinc, aluminum, or magnesium, is injected under high pressure into a mold to form a precise, solid part. The material is added to the mold to create the final shape, rather than removing material from a larger block, as in subtractive processes like machining, milling, or drilling.

In die casting, the mold defines the part’s geometry, and once the metal cools and solidifies, the part is ejected, requiring minimal post-processing (though trimming or surface finishing may be needed). This contrasts with subtractive methods, where material is cut away to achieve the desired shape.
