Die Casting vs Gravity Casting: Aluminum Casting Components

Aluminium casting technology offers multiple manufacturing routes, with die casting and gravity casting representing two of the widely adopted methods.

Both processes transform molten aluminum into precise, functional shapes, but they differ significantly in pressure application, mold design, metallurgical outcomes, production speed, and economic suitability.
Die casting typically excels at producing thin-walled, high-volume, and intricately detailed components with good surface finish and dimensional consistency.

Gravity casting—whether permanent mold or sand casting—generally produces parts with lower porosity, better heat-treatable microstructures, and improved mechanical performance for structural or pressure-containing applications.
