China's Dominance in Stamped Metal Production

Sand casting is one of the oldest and most widely used casting processes in the manufacturing industry. It involves creating a mold from sand and then pouring molten grey cast iron into the mold cavity. The process begins with the preparation of a mold, which consists of two halves the cope (upper half) and the drag (lower half). The sand is mixed with a binder, usually clay, and water to create a mold that can hold its shape when the molten metal is poured.

High precision casting encompasses several methods, the most common of which are lost-wax casting and investment casting. In lost-wax casting, a pattern made from wax is coated with a ceramic material to create a mold. Once the mold setting is complete, the wax is melted away, leaving an empty cavity. Molten metal is then poured into this cavity and allowed to solidify, resulting in a precise metal replica of the original wax component.
