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.

The tactile experience of a smoothly cast iron object often invokes a sensory connection, creating an appreciation not only for the item itself but also for the craftsmanship involved in its creation. Contemporary artists continue to explore sand cast iron, pushing boundaries and challenging conventions, while craftspeople preserve the traditional methods that have defined this medium for centuries.

Green sand iron casting is a widely used method in the metalworking industry, renowned for its efficiency, cost-effectiveness, and versatility. This form of casting involves the use of a mixture of sand, clay, and water, which is called green sand, to create molds for molten iron. The term green refers to the fact that the sand is damp and not yet baked or hardened, distinguishing it from other types of casting processes. This article will explore the various aspects of green sand iron casting, including its composition, advantages, applications, and environmental considerations.
