Il gesso di Parigi è un minerale di solfato di calcio che viene utilizzato in vari ambiti, dalla costruzione all'arte. Si presenta sotto forma di polvere bianca fine e, quando miscelato con acqua, si trasforma in una pasta liscia che indurisce in tempi rapidi. Questa proprietà di rapida solidificazione lo rende un materiale ideale per la creazione di stampi utilizzati nella fusione.

1. Shell Coating Applying a thin layer of ceramic coating to the mold can improve surface finish and reduce defects. This technique acts as a barrier and provides a smoother surface for the molten metal.

2. Complex Geometries The intricate designs achievable through precision casting are invaluable in modern manufacturing. Producers can create complex geometries that would be difficult or impossible to achieve with traditional fabrication methods.

Dry sand casting differs from its green counterpart primarily in its use of dried molding sand. The molds are baked in an oven to harden the sand, creating a more rigid mold. This method reduces the moisture content and, in turn, the likelihood of defects like gas porosity.

Die casting, on the other hand, involves forcing molten aluminum into hardened steel molds. This method is highly efficient for mass production and delivers parts with excellent dimensional accuracy. Die casting is widely used in automotive components, toys, and hardware due to its ability to produce lightweight yet durable products.
