The process.

Liquid aluminium, often made of brill alloy, is introduced by gravitational force and then left to cool and solidify. A semi-finished product is obtained to be used for surface polishing. This type of casting is particularly suitable for the production of aesthetic parts for anodic oxidation and oxycoloring.
