2. Centrifugal Pumps These pumps use rotational energy to move fluids. While they are generally less precise than positive displacement pumps, advances in technology have led to the development of highly efficient models that can deliver consistent performance in many applications.

At its core, sand casting involves creating a mold from sand, which is then filled with molten metal to create a desired shape. The process begins with the creation of a pattern, usually made of wood or metal, which reflects the final product's dimensions. This pattern is placed in a molding box filled with sand, often combined with a binding agent, to ensure it holds its shape. After the pattern is removed, the cavity left behind serves as the mold for pouring the molten lead.

4. Design Flexibility Compound dies can be designed to accommodate a variety of operations, making it easier to produce complex parts. This flexibility allows manufacturers to adapt to changes in product design without needing extensive retooling.
