Aluminum Gravity Die Casting

Aluminum gravity die casting is a manufacturing process where molten aluminum is poured into a preheated steel mold, relying on gravity to fill the cavity. This technique is well-suited for producing medium to large parts with complex geometries and a high degree of dimensional accuracy. Typical specifications for this process include a casting temperature of around 650-750C (1202-1382F), and molds are often preheated to improve metal flow and reduce defects. The process generally allows for thicker walls and larger components compared to pressure die casting, but with a slightly longer cycle time. It offers good surface finish and mechanical properties, making it ideal for parts requiring strength and durability without the need for extensive post-casting machining.
