Gravity Die Casting is a permanent mould casting process, where the molten metal is poured from a vessel or ladle into the mould. The mould cavity fills with no force other than gravity, filling can be controlled by tilting the die. Undercuts, and cavities can be incorporated into the component form with the use of sand cores. This process gives a better surface finish than sand casting as well as better mechanical properties, both due to rapid solidification.
Additionally, this process has a higher casting rate than aluminium sand casting, however, the metal moulds are a higher cost than sand. Advantages of this process include the possibility of low gas porosity, and fine grain sizes can be achieved.
Compared to sand casting, this process requires less finishing and fettling and gravity die casting tends to produce a higher quality product. The Gravity die casting production method is generally less cost effective in the manufacture of tooling compared with sand casting.
Gravity die casting is often a manual process, with the molten metal added with the use of a ladle. However, for some high volume applications it is also possible to use an automated ladle to pour the molten metal. The speed and the direction of the filling can also be controlled by tilting the die.
Apart from the method by which the molten metal is poured into the die cavity, and the gravity die material, the casting process is essentially the same as sand casting. It involves four steps:
Gravity die casting is a natural partner to sand casting, and allows us to offer the customer the most cost effective route for casting manufacture.
