Tonnage in die casting refers to the amount of clamping force that is needed to hold the die closed while molten metal is injected into the cavity. This clamping force is essential to prevent the die from opening under the pressure of the injected metal, which can reach several thousand psi. The tonnage required is usually expressed in tons and is determined by various factors, including the size and shape of the part, the type of metal being cast, and the injection pressure.

Additionally, sanding helps to prepare the surface for other finishing processes, such as painting or seasoning in the case of cookware. A well-sanded surface increases the adhesion of coatings, leading to a more durable finish. Furthermore, sanding can enable the designer or artisan to achieve specific textures and patterns that may enhance the piece's visual appeal.

In conclusion, green sand remains a staple in the metal casting industry due to its unique combination of strength, versatility, and cost-effectiveness. With its ability to accommodate various metals and the potential for recycling, green sand casting is a sustainable choice for modern foundries. As technology continues to evolve, it is likely that the applications and benefits of green sand will only grow, solidifying its place as an essential material in metal casting for years to come.
