Gravity Die Casting is a low-pressure method that utilizes the natural force of gravity to poure molten metal into the mould and form the shape. The mould cavity fills with only gravity, sand cores are usually used to incorporate cavities into the component form.
Our gravity casting parts are commonly used for:

About Gravity Castings Work
Gravity Die Casting gives a better surface finish than sand casting as well as better mechanical properties, both due to rapid solidification. Gravity casting is widely used in industry due to its cost-effectiveness.
