The molten metal is then poured a second time into the "Shell" or 'Casting cluster', and left to cool in a controlled temperature environment, using an autoclave. The shell, previously cleaned, is now coated with another layer of alloying material. To do this, the first layer of metal is melted, while the second one is cooled by cooling water circulating through it.

This process has been used for many years but has been improved by modern technology and has given rise to a new technology called “microfusione". This process works by heating the metal in a controlled temperature environment and then cooling it again in a controlled temperature environment. The cooled metal is then poured into the "Shell" or 'Casting cluster', and left to cool in a controlled temperature environment, using an autoclave.

This process makes sure that no hardening occurs between layers of material. After mixing all layers together again, they are reheated in an autoclave until they reach the melting point of their respective materials; at this point, they are removed from the autoclave and further processing can be carried out on them.
